Reproductive Health and Newborn Nursing 13 Flashcards
Humans typically have 23 pairs of chromosomes in their cells, for a total of 46 chromosomes. Among these 23 pairs:
- 22 pairs are autosomes, which are non-sex chromosomes. These autosomes carry genes that are responsible for various traits and functions in the body.
- 1 pair consists of sex chromosomes, which determine an individual’s sex. In males, this pair consists of one X chromosome and one Y chromosome (XY), while in females, it consists of two X chromosomes (XX).
.
A chromosome is a structure found in the nucleus of eukaryotic cells, including human cells, that carries genetic information in the form of genes. Here are the key points from your description:
- Package of Genes: Chromosomes are indeed packages of genes. Genes are segments of DNA that contain instructions for various biological functions and traits. Each chromosome contains many genes arranged along its length.
- Inheritance: Chromosomes play a critical role in inheritance. You inherit one set of chromosomes from each of your parents. These chromosomes contain the genetic information that determines your traits and characteristics. When you have children, you pass on a combination of your chromosomes to them.
- Pairs: Chromosomes come in pairs in most human cells because you inherit one chromosome from each parent for each corresponding chromosome in the pair. This pairing ensures that you have a mix of genetic material from both parents.
- Chromosome Number: Humans typically have 23 pairs of chromosomes, for a total of 46 chromosomes in most cells. This includes 22 pairs of autosomes (non-sex chromosomes) and 1 pair of sex chromosomes (X and Y in males, and two X chromosomes in females).
- Structure: Chromosomes have a distinctive structure with a centromere (a constriction point), two arms (short and long), and specific banding patterns when stained and viewed under a microscope. These banding patterns help identify and distinguish different chromosomes.

Genetic Terminology:
- Genotype refers to the genetic makeup of an individual when discussing a specific gene pair, but it can also be used to refer to an individual’s entire genetic makeup.
- Phenotype represents the observable expression of an individual’s genotype, including physical features, biochemical or molecular traits, or psychological traits.
- Dominant traits are expressed or phenotypically apparent when only one copy of an allele is associated with the trait.
- Recessive traits are expressed only when two copies of the alleles associated with the trait are present.
Karyotype
Chromosomal Analysis for Paternity Testing:
- This type of analysis involves the visual examination and assessment of the number, form, and size of an individual’s chromosomes. It is commonly used in paternity tests to establish biological relationships.
- The analysis typically utilizes white blood cells or fetal cells obtained from amniotic fluid samples.
- Chromosomes are numbered from largest to smallest, designated as 1 to 22, with sex chromosomes indicated as X and Y. This numbering system allows for the identification and comparison of specific chromosomal patterns to determine paternity.

Chromosomal Abnormalities
Chromosomal Abnormalities may be
Inherited (e.g., sickle cell, cystic fibrosis, etc.)
Spontaneous (occurs spontaneously at the time of conception)
Acquired Chromosomal Abnormalities (Environmental): These abnormalities are not related to external environmental factors but rather to changes that occur within the developing fetus’s environment. These changes can be caused by various factors, including exposure to certain substances or infections during pregnancy, which can lead to chromosomal abnormalities in the developing fetus.
Chromosomal Abnormalities 2
Types of Chromosomal Abnormalities:
Abnormalities of Chromosome Number:
- Monosomies: When an individual has only one copy of a particular chromosome instead of the usual two.
- Trisomies: When an individual has an extra copy of a particular chromosome, resulting in three copies instead of the usual two.
- Polyploidy: Involves having multiple sets of chromosomes, which can lead to various abnormalities in the number of chromosomes.
Abnormalities of Chromosome Structure:
- Deletions: Occur when a portion of a chromosome is missing or deleted, leading to insufficient genetic material.
- Inversions: Involve the reversal or flipping of a segment of a chromosome, changing its orientation.
- Translocations: Occur when a segment of a chromosome breaks off and attaches to another chromosome or a different part of the same chromosome.
Sex Chromosome Abnormalities:
- These abnormalities affect the sex chromosomes (X and Y) and can result in ambiguous gender at birth, making it challenging to determine if an individual is male or female.
- For example, an infant may have swollen labia and an enlarged clitoris, resembling a misshapen penis. In some cases, determining the true gender may require waiting until the child can express their gender identity.
Chromosome Abnormality:Number
Deviations in Chromosomal Abnormalities:
- Polyploidy: In this type of deviation, the number of chromosomes is an exact multiple of the haploid number, which means it has more than the usual diploid set of chromosomes (one set from each parent). Polyploidy is typically incompatible with life, and it involves having multiple complete sets of chromosomes.
- Aneuploidy: Aneuploidy is a deviation where the number of chromosomes is not an exact multiple of the haploid set. This can result in either monosomies (having one less chromosome) or trisomies (having one extra chromosome). Trisomies are the most common form of aneuploidy, where there are three copies of a particular chromosome instead of the usual two.
Chromosome Abnormality:Number
Incidence of Trisomy 21 (Down Syndrome):
- The incidence of trisomy 21, where the 21st chromosome has 3 chromosomes instead of 2, varies depending on the stage of pregnancy and the outcome:
- At Birth: The incidence of trisomy 21 in newborns is relatively low, at approximately 0.6%.
- Stillbirths (Greater than 20 Weeks): Trisomy 21 is observed in about 6% of stillbirths that occur after 20 weeks of gestation.
- Spontaneous Abortions (Less than 20 Weeks): Trisomy 21 is much more common in cases of spontaneous abortions that occur before 20 weeks of gestation, with an incidence ranging from 60% to 80%.

Down syndrom increases with age because teh chromosomes as well as the eggs deteriorate and they are less accurate as they get older. This starts at age 35
Characteristics of a Child with Trisomy 21 (Down Syndrome):
Physical and Developmental Features:
- Growth failure, often resulting in shorter stature.
- Intellectual and developmental challenges, commonly categorized as mild to moderate mental retardation.
- A flat back of the head.
- Distinctive facial features, such as abnormal ears, a broad flat face, slanting eyes, and an epicanthic eyefold.
- A short nose and a small, arched palate.
- Short and broad hands with a single palmar crease.
- Many “loops” or dermatoglyphic ridges on the fingertips.
- A big, wrinkled tongue.
- Dental anomalies.
- Congenital heart disease.
- Enlarged colon.
Other Physical Characteristics:
- Unilateral or bilateral absence of one rib.
- Intestinal blockage.
- Umbilical hernia.
- Abnormal pelvis.
- Diminished muscle tone.
- Big toes that are widely spaced.
Chromosomal Abnormality:Structure
Translocation in Chromosomes:
- Translocation is a genetic phenomenon involving the exchange of chromosomal material between two non-homologous chromosomes (chromosomes that are not the same in terms of size or genetic content).
- Translocations can occur in any chromosome, and there are two main types:
- Balanced Translocation: In this type, genes are rearranged between chromosomes, but no genetic material is added or lost. Individuals with balanced translocations typically do not show any physical abnormalities because all genetic material is still present.
- Unbalanced Translocation: In this type, genetic material is either added or subtracted during the translocation process. Unbalanced translocations can result in genetic disorders and physical abnormalities because the amount of genetic material is not correct.
- The causes of translocations can be varied and may include exposure to certain drugs, viruses, or radiation. However, in many cases, the exact cause of a translocation may not be apparent, and it can occur spontaneously during cell division or meiosis.
Chromosomal Abnormality:Structure
Phenotypically normal individuals often have balanced translocations, meaning that they carry rearranged genetic material between chromosomes, but outwardly, they do not exhibit any noticeable physical abnormalities or differences. The reason for their normal appearance is that despite the rearrangement of genetic material, all the essential genes and genetic content are still present and functioning properly.
In these cases, the changes in the genetic material are subtle and typically do not result in any observable effects on the individual’s physical appearance or health. However, it’s essential to note that even though these individuals may appear normal, they can still potentially pass on the balanced translocation to their offspring, which could lead to unbalanced translocations and associated genetic disorders in the next generation.
Genotypically and phenotypically abnormal.
- Genotypically Abnormal: This means there is an imbalance in the genetic material because some genetic material is either missing or extra. This can lead to problems with the individual’s overall genetic makeup.
- Phenotypically Abnormal: The phenotype refers to the physical and observable characteristics of an individual, such as appearance, health, and developmental status. When unbalanced translocations disrupt the normal genetic balance, it can result in physical abnormalities and developmental issues. These can include intellectual disabilities, birth defects, and other health problems, depending on which genes are affected and the extent of the imbalance.
So, unbalanced translocations can indeed lead to significant developmental and health challenges for individuals who have them. The specific effects can vary widely depending on the particular genes involved and the severity of the imbalance.
Autosomal Dominant Inheritance
- Only one copy of the dominant variant allele is required for phenotypic expression.
- When heterozygous, there is a 50% chance of passing the variant allele on to offspring.
- Vertical transmission.
Autosomal Recessive Inheritance
Just look at the punnet square for sickle cell
- Phenotypic expression requires two carriers of the variant allele, specifically, one from each parent (mom and dad).
- Neither of the parents expresses the genetic mutation, but both are carriers.
- Both parents must be heterozygous carriers of the variant allele.
- The offspring have a 25% chance of being affected, a 50% chance of being carriers, and a 25% chance of being unaffected.
- This type of transmission is referred to as “Horizontal Transmission.”

- X-linked inheritance mimics autosomal dominant inheritance but lacks male-to-male transmission due to the fact that males do not pass on an X chromosome to another male; instead, they pass on a Y chromosome.
in X-linked inheritance, males can’t pass the trait to other males because they give their sons a Y chromosome instead of an X. Since the trait is carried on the X chromosome, only females can pass it to both their sons and daughters because they have two X chromosomes (XX), while males have one X and one Y chromosome (XY). This means that if a father has the X-linked trait, he can only pass it on to his daughters, not his sons, because sons get their Y chromosome from their fathers. So, there’s no male-to-male transmission of the trait in X-linked inheritance.
- X-linked recessive inheritance is characterized by the presence of a recessive gene on the X chromosome (X-linked) and is typically considered “weaker” because males have only one X chromosome (XY).
- Most X-linked recessive conditions are passed from a carrier mother to her male offspring.
- Females can also inherit X-linked recessive conditions but are less commonly affected compared to males.
X-linked recessive inheritance is when a certain gene is located on the X chromosome (one of the two types of sex chromosomes) and follows a particular pattern.
In this pattern, the gene is “weaker” or less noticeable because males have only one X chromosome and one Y chromosome (XY), while females have two X chromosomes (XX).
When a mother carries this recessive gene but doesn’t show any signs of the condition herself (she’s a carrier), she can pass it on to her sons. This means her sons have a higher chance of inheriting the condition.
Females can also inherit this gene, but they are less likely to show the condition because they have two X chromosomes, and the presence of a healthy X chromosome can often compensate for the recessive gene on the other X chromosome. So, they are carriers too, but the condition is less common in them compared to males.
X-linked Dominant Inheritance
- Multifactorial inheritance involves the interaction of both genetic and environmental factors in the development of a condition or birth defect.
- For example, conditions like cleft palate or spina bifida can result from a combination of genetic predisposition and environmental influences, such as a deficiency in folic acid during pregnancy.
Environmental Etiology of Human Anomalies
Etiologies
Factors contributing to multifactorial inheritance and birth defects include:
- Environmental factors: Certain regions with high levels of chemicals, often due to industrial activity, can increase the risk of genetic abnormalities.
- Maternal conditions: Conditions such as alcoholism, diabetes, smoking, and poor nutrition during pregnancy can have adverse effects on fetal development, including changes in DNA.
- Infectious agents: Infections like toxoplasmosis, rubella, syphilis, CMV (cytomegalovirus), and varicella (chickenpox) during pregnancy can lead to birth defects in the fetus.
- Mechanical problems: Amniotic band constrictions, where strands of the amniotic sac wrap around fetal limbs or other body parts, can result in the constriction and abnormal growth of the fetus. The exact cause of this condition is not always clear.
- Chemicals, drugs, radiation, and hyperthermia: Exposure to harmful chemicals, certain medications, radiation, and high body temperature (hyperthermia) during pregnancy can increase the risk of birth defects. Cooling measures and medications like acetaminophen (Tylenol) may be used to mitigate hyperthermia’s effects on the developing fetus.

Genetic Evaluation and Counseling
Genetic counseling is a process that individuals or their relatives, who are at risk of inheriting a genetic disorder, can undergo. During this process, they receive information about the nature and consequences of the disorder, the likelihood of developing it, and the available options for managing and planning for their family to prevent, mitigate, or avoid the disorder (Lopes, de Omena Bomfim, & Flória-Santos, 2015).
There are several reasons why an individual should be referred to genetic counseling (see Box 10.2), and the ideal time to seek genetic counseling is before conception. This proactive approach allows for informed decision-making and family planning in cases where there is a known family history of genetic disorders or concerns about potential risks.
The decision tree you’ve provided is a simplified way to help individuals make informed choices about prenatal testing for birth defects. It encourages individuals to consider their personal preferences, values, and priorities when deciding whether or not to pursue prenatal testing and which specific tests might be suitable for their situation. Let’s break down the decision tree:
First Set of Questions:
- “Would knowing that my baby has a birth defect help me prepare for having a baby with special needs?”
- “Would I consider ending my pregnancy if the baby had a birth defect?”
If you answered NO to both questions:
- You may decide not to have any prenatal testing for birth defects. This choice aligns with the preference of some individuals who do not wish to undergo testing if they do not intend to make any changes to the pregnancy based on the results.
If you answered YES to either question:
- You may want to consider having some type of prenatal testing, as you are open to receiving information about the potential presence of birth defects.
Second Set of Questions for Further Decision-Making:
- “Do I want to know whether my pregnancy is at higher risk for certain birth defects?”
- “Do I need more information before deciding to have a diagnostic procedure?”
- “Am I willing to accept a test that might miss these birth defects?”
If you answered YES to these questions:
- You may want to consider having Serum Integrated Screening or Sequential Integrated Screening. These tests can provide information about the likelihood of certain birth defects without a high risk of miscarriage.
If you answered YES to these questions:
- You may want to consider having Chorionic Villus Sampling (CVS) or Amniocentesis. These are diagnostic procedures that can provide more definitive information about the presence of birth defects but come with a small risk of miscarriage.
Ultimately, the decision regarding prenatal testing should be made in consultation with a healthcare provider. They can provide detailed information about the available tests, their risks and benefits, and how the results may impact your pregnancy management and decisions. Additionally, individuals should consider their own values, beliefs, and emotional readiness when making choices about prenatal testing.

Here are the steps involved in the preconception counseling process:
Beginning:
- Initiating the preconception counseling process and making referrals for additional genetic information.
Taking:
- Collecting a comprehensive family history by discussing specific diseases or conditions that may run in the family.
Scheduling:
- Arranging genetic testing as necessary based on the family history and risk factors.
Explaining:
- Providing detailed explanations about the purposes and the potential risks and benefits associated with all screening and diagnostic tests (see Laboratory and Diagnostic Tests 10.1).
Answering:
- Addressing any questions and concerns that individuals or couples may have regarding the counseling process and genetic testing.
Nursing Roles and Responsibilities (cont.)
In the context of genetic counseling, there are several important aspects to consider:
Discussing:
- Engaging in discussions about the costs, benefits, and risks associated with using health insurance for genetic testing.
- Addressing potential risks of discrimination related to genetic information, including employment and insurance discrimination.
Recognizing:
- Recognizing ethical, legal, and social issues that may arise, especially if the individual or couple decides to end their pregnancy based on genetic testing results. These issues can involve complex moral and legal considerations.
Safeguarding:
- Ensuring the privacy and confidentiality of the patient’s health information, following the regulations outlined in the Health Insurance Portability and Accountability Act (HIPAA).
Monitoring:
- Being attentive to the emotional reactions of individuals or couples after they receive genetic information. Sometimes, people may initially say they are okay when they are not, and it’s essential to provide ongoing support and follow-up.
Providing:
- Offering emotional support throughout the counseling process, as individuals and couples may experience stress, anxiety, or grief when dealing with genetic testing and potential outcomes.
Referring:
- Referring individuals or couples to appropriate support groups or mental health professionals if needed. Support groups can provide a valuable outlet for sharing experiences and coping with the emotional aspects of genetic testing and its implications.
Newborn screening is a critical medical procedure conducted shortly after a baby’s birth to check for various genetic abnormalities and medical conditions. The primary goal is to identify any underlying health issues in infants before they are discharged from the hospital. This early screening allows for the prompt diagnosis and intervention of conditions that may not be immediately apparent but could have serious consequences if left untreated. It helps ensure that newborns receive the necessary medical care and support to start their lives on the right foot.

Increase of Infertility throughout the western world especially.
Infertility rates have been on the rise in the Western world, and several factors contribute to this increase. Some of the key factors include:
- Ovarian Dysfunction: When the ovaries do not function properly and do not release eggs, it can lead to difficulties in conceiving. Ovulatory disorders can be a significant cause of infertility.
- Advancing Age: As women age, the quality and quantity of their eggs (oocytes) naturally decrease. This reduced oocyte quality can make it more challenging to achieve pregnancy, especially as women get older.
- Weight Issues: Both being overweight and underweight can affect fertility. Excess body weight can lead to hormonal imbalances, while being underweight can disrupt the menstrual cycle.
- Immune System Disorders: Certain immune system disorders or autoimmune conditions can interfere with fertility by affecting the reproductive organs or the fertilization process.
- Psychological Stress: High levels of stress can negatively impact fertility. Stress can disrupt hormonal balance and interfere with the menstrual cycle.
The intact hypothalamic-pituitary-gonadal (HPG) axis is indeed essential for the normal functioning of the female reproductive system, including the ability to conceive and prepare the body for pregnancy.
- Normal functioning of the intact hypothalamic-pituitary-gonadal axis is essential.
- All these hormones must work correctly for a woman to conceive and prepare her body for pregnancy.
FSH need to work well, the leuthenazing hormone etc…
Increased infertility related to tubal/pelvic pathology:
- STIs (Sexually Transmitted Infections): Certain sexually transmitted infections, such as chlamydia and gonorrhea, can lead to scarring and damage of the fallopian tubes. This can obstruct the pathway for the egg to meet the sperm, making it difficult for fertilization to occur.
- Fibroids: Fibroids are noncancerous growths in the uterus. Depending on their size and location, they can interfere with the uterine lining’s ability to support implantation of a fertilized egg. This can reduce the chances of successful pregnancy.
- Cervical Stenosis: Cervical stenosis refers to a narrowing or blockage of the cervix (the lower part of the uterus). This condition can disrupt the normal passage for sperm to enter the uterus and reach the egg for fertilization, which can result in infertility.
- Endometriosis: Endometriosis is a condition in which tissue similar to the uterine lining grows outside the uterus. This can lead to the formation of adhesions and scar tissue in the pelvic area. Endometriosis can interfere with the proper functioning of the ovaries, fallopian tubes, and uterus, making it more challenging for conception to occur.
Tubal/Pelvic Pathology:
- STIs can cause scarring of the fallopian tubes.
- Fibroids can scar the uterine lining, making it difficult for the fetus to find a suitable place to implant.
- Cervical stenosis can disrupt the normal function of the cervix, preventing sperm from entering.
- Endometriosis involves the growth of uterine lining tissue outside of the uterus.

Detection of Ovulation
Methods for Assessing Ovulation:
Direct Proof:
- Retrieval of an ovum from the uterine tube (invasive procedure)
Indirect Methods:
- Over-the-counter ovulation kits (tests for LH surge) 24-36 hours before ovulation
- Serum progesterone levels (elevated levels indicate ovulation)
- Basal body temperature tracking
- Monitoring cervical mucus changes
- Ultrasound examination of the ovaries
Basal Body Temperature slide 49
- BBT monitoring involves tracking daily body temperature to identify changes in the menstrual cycle.
- During the follicular phase, BBT typically shows a slight decrease in temperature.
- In the luteal phase, BBT usually increases.
- These temperature changes can help pinpoint the timing of ovulation.
- Charting BBT can be a useful tool for tracking and predicting fertility.
Sure! BBT monitoring is a way to keep track of your body temperature every day to help you understand your menstrual cycle better.
Here’s how it works:
- Follicular Phase: At the start of your menstrual cycle, during the follicular phase, your body temperature is a bit lower than usual.
- Luteal Phase: As you move into the luteal phase (after ovulation), your body temperature tends to go up a bit.
- Ovulation: The point when your temperature goes up is usually a sign that you’ve ovulated, which means you’re releasing an egg from your ovaries.
By charting these temperature changes over time, you can figure out when you’re most likely to ovulate. This information is valuable for women who want to get pregnant because they can focus on having sex around the time of ovulation when it’s easiest to conceive. It can also help those who don’t want to get pregnant to avoid fertile days.
So, in simple terms, BBT monitoring helps you keep track of your body temperature to know when you’re most fertile or when your period might come.
The best time for fertilization, also known as the fertile window, is typically centered around the time of ovulation. Ovulation is when a mature egg is released from the ovaries and can be fertilized by sperm. In the menstrual cycle:
- Ovulation: This usually occurs in the middle of the menstrual cycle, roughly around day 14 in a 28-day cycle. However, it can vary from person to person and cycle to cycle.
- Fertile Window: The fertile window includes the days leading up to and immediately following ovulation. Sperm can survive inside the female reproductive tract for up to several days, and the egg is viable for about 12-24 hours after ovulation. So, the fertile window typically spans a few days before ovulation and the day of ovulation itself.
To maximize your chances of fertilization if you’re trying to conceive, it’s recommended to have regular intercourse during this fertile window. Some methods, like BBT monitoring, ovulation predictor kits, and tracking cervical mucus changes, can help you estimate when you’re likely to ovulate and pinpoint your fertile days more accurately.
Remember that individual variations in menstrual cycles can affect the timing of ovulation, so it’s important to track your own cycle to identify your specific fertile days. Additionally, if you’re struggling to conceive, it’s advisable to consult with a healthcare provider for personalized guidance and potential fertility testing.
Assessment of Cervical Mucus
Low Viscosity
High Spinbarkeit test
- Low Viscosity: Viscosity refers to the thickness or stickiness of a substance. In the context of cervical mucus, low viscosity means that the mucus is more fluid and watery in consistency. This type of mucus is typically observed at different times in a woman’s menstrual cycle, and it is associated with increased fertility. It allows sperm to swim more easily through the cervix and into the uterus to reach the egg.
- High Spinbarkeit Test: The Spinbarkeit test, also known as the cervical mucus elasticity test, is a way to assess the stretchiness or elasticity of cervical mucus. During certain times in the menstrual cycle, particularly around ovulation (the release of an egg from the ovary), cervical mucus becomes more stretchy and can be stretched between the fingers without breaking. This characteristic, known as “high Spinbarkeit,” is another sign of increased fertility. It indicates that the cervical mucus is supportive of sperm transport, making it easier for sperm to travel through the cervix and into the reproductive tract.
In summary, these assessments are used to evaluate the quality and characteristics of cervical mucus, providing important information for individuals who are trying to conceive or track their menstrual cycle for various reasons, including family planning. Low viscosity and high Spinbarkeit are both indicators of fertile cervical mucus, which can enhance the chances of successful fertilization.

Ovulation Inducing Rx and Selected Treatment Options for Infertility:
Fertility Drugs:
1. Clomiphene citrate (Clomid)
- A nonsteroidal synthetic antiestrogen used to induce ovulation.
- Typically discontinued after three cycles of use.
- Administered daily for 1 week starting after day 5 of the menstrual cycle.
- Human menopausal gonadotropin (HMG) (Pergonal)
- Induces ovulation by directly stimulating ovarian follicles.
- Similar to Clomid.
Artificial Insemination:
- The insertion of a prepared semen sample into the cervical os or intrauterine cavity.
- Enhances the chances of conception by depositing sperm closer to the egg.
- Can use sperm from the husband or a donor.
- Couples should be aware that the procedure may need to be repeated if not successful initially.
Nursing Considerations:
- Nurses should advise couples on the proper administration and timing of fertility drugs.
- For artificial insemination, nurses should provide guidance on the procedure and manage expectations regarding potential repetition if the first attempt is unsuccessful.
Hormone Analysis for Menstrual Irregularities and Assisted Reproductive Technology (ART):
Prolactin and Thyroid:
- Used to diagnose the cause of irregular or absent menstrual cycles.
- Elevated prolactin levels or thyroid dysfunction can contribute to menstrual irregularities.
Progesterone:
- Necessary to maintain pregnancy.
- A deficiency in progesterone can lead to difficulties in maintaining a pregnancy.
FSH (Follicle-Stimulating Hormone) and Estradiol:
- Utilized when assisted reproductive technology (ART) is employed to predict the ovarian response to stimulants.
- Monitoring these hormone levels helps assess the readiness of the ovaries for fertility treatments and ART procedures.
Hormone analysis is a medical test that checks the levels of certain hormones in the body. Here’s how it’s used for menstrual irregularities and assisted reproductive technology (ART):
Prolactin and Thyroid: These tests help find the reasons for irregular or missing periods. If prolactin levels are too high or if the thyroid isn’t working properly, it can cause problems with your menstrual cycle.
Progesterone: This hormone is needed to keep a pregnancy going. If there’s not enough progesterone, it can make it hard to stay pregnant.
FSH (Follicle-Stimulating Hormone) and Estradiol: These tests are used when people are getting fertility treatments like in vitro fertilization (IVF). They help doctors figure out how the ovaries are responding to the medications used in these treatments. This helps assess if the ovaries are ready for fertility treatments and ART procedures.
In simple terms, hormone analysis checks these hormones to understand why periods might be irregular, why it’s hard to maintain a pregnancy, or to see if the ovaries are ready for fertility treatments. It’s a way for doctors to get important information about your reproductive health.
Prolactin is a hormone produced by the pituitary gland in the brain, and its primary role is to stimulate the production of breast milk in response to breastfeeding. Here’s why high levels of prolactin can lead to irregular or absent menstrual cycles and how it happens:
Inhibits Gonadotropin-Releasing Hormone (GnRH): Prolactin has an inhibitory effect on the release of Gonadotropin-Releasing Hormone (GnRH) from the hypothalamus, another part of the brain. GnRH is a key hormone that helps regulate the menstrual cycle. When prolactin levels are elevated, they can suppress the secretion of GnRH.
Disruption of the Menstrual Cycle: GnRH is responsible for triggering the release of hormones like Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) from the pituitary gland. FSH and LH play essential roles in the menstrual cycle, including the development of ovarian follicles and the release of eggs (ovulation). When there’s less GnRH available due to high prolactin levels, it can disrupt the normal hormonal signals that control menstruation.
Hysterosalpingogram
Hysterosalpingogram (HSG):
- A somewhat invasive procedure used to examine the uterus and fallopian tubes.
- Typically performed around Day 5 of the menstrual cycle, which falls in the late follicular or early proliferative phase.
- It involves the injection of a contrast dye into the uterus and fallopian tubes to evaluate their structure and detect any blockages or abnormalities.
Hysterosalpingogram
Patent fallopian tubes
Hysterosalpingogram (HSG):
- Typically not performed as a routine procedure but rather when something abnormal is visualized with other tests.
- Used to investigate and confirm specific issues if necessary.
Pelvic Laparoscopy it is the last resort:
- Considered a less invasive procedure compared to open surgery.
- Often preferred for its faster recovery time.
- Used for diagnosing and treating various gynecological conditions and abnormalities.
Semen Analysis:
- A critical evaluation of semen to assess its fertility potential.
- It involves several parameters, including:
- Sperm count: To determine the number of sperm present in a given sample.
- Sperm morphology: To assess the shape and structure of sperm.
- Sperm motility: To check if sperm can swim effectively.
- All of these conditions need to meet specific criteria for a higher likelihood of successful pregnancy.
- Approximately 2 million sperm are typically released with each ejaculation, but a significantly lower number can still result in a pregnancy under certain conditions.
