Infertility, Anvoluation, Amenorrhea Flashcards
When is Unexplained Infertility diagnosed?
Once a woman has unsuccessfully been trying to get pregnant for at least one year and has had all the routine infertility evaluations done including assessment of ovulation, a semen analysis, a Hysterosalpingogram (HSG) to evaluate any uterine blockages, blood tests to asess ovarian reserve and potentially a laparoscopic investigation.
When those all come back normal, a woman is diagnosed with unexplained fertility.
Is unexplained infertility an acceptable diagnosis?
No! The problem is that the convo often stops with unexplained infertility. A woman is suggested to go through IVG if she wants to get pregnant or to consider surrogacy or adoptin, but there isn’t any additional conversation about her nutritional status, hormone balance, egg quality, or other areas of her systemic function.
True infertility makes up what percentage of the entire population?
Very small and is often observable, such as structural damage, scar tissue build-up, or other reproductive abnormalities that inhibit ovulation or proper implantation.
Is it true that olvuation always occurs on cycle day 14 or halfway through a woman’s menstrual cycle?
No, but women and even physicians and ferility specialists are taught this incredibly misleading info. This can lead women to inaccurately time their sexual encounters and it also leads to inaccurate test results and poor outcomes on therapies such as artificial insemination.
Can LH tests guarantee when exactly a woman is going to ovulate?
No!
What is one of the biggest factors that can play a role in ovulation variability?
Stress, whether internal, emotional, psychological, or environmental.
From a biopsyhiological perspective, how does stress effect ovulatoin?
In the presence of norepinphrine, which is released by the locus Coeruleus and Amygdala in the brain, as well as the adrenals i response to stress, the hypothalamus and pituitary instruct the ovaries to shut down their follicle development and hormone production, stunting ovulation and contributing to the development of cysts.
What is the longest phase of the menstrual cycle?
The luteal phase, typically between 10-16 days.
Anything longer than BLANK days in the luteal phase is typically a sign of pregnancy?
16 days.
On occasion, some women may experience extremely long luteal phases without being pregnant as a result of BLANK?
Corpus Luteum Cyst.
For some people, early ovulation may result in what?
Prematurely developed ovarian follicle, which may impact the quality of their corpus lteum, having an impact on the quantity of progesterone they are able to produce.
Early ovulation can often be a sign of what?
Estrogen excess (not estrogen dominance0.
In the follicular phase, if estrogen levels are higher than normal due to poor estrogen clearance and/or xenoestrogen exposure, they may dampen BLANK and BLANK, negatively affecting BLANK?
FSH and LH; ovarian follicle development (which requires ample FSH).
In early ovulation, estrogen levels may be at or higher than 200 pg/ml which can trigger the BLANK, initating BLANK and an early ovulation.
the LH surge, initiating luteinization.
In this case, although ovulation may occur and there is potential for fertilization, the corpus luteum may not form properly due to poor ovarian follicle development, resulting in lowered progesterone and an increased risk for miscarriage.
To determine if early ovulation could be negatively impacting your client’s hormonal health you’ll want to take note of what?
When they ovulate in their cycle and observe whether or not they experiene any luteal phase symptoms.
You can also observe their cycle charts and/or BBTs to assess the quality of their temperature rise.
Do they ovulate routinely before cycle day 12 or 13? If so, do they experience any other signs of estrogen excess? How about symptoms of low progesterone such as short luteal phases, PMS, or premenstrual spotting? Do they have a history of miscarriage?
What can indicate poor corpue luteum quality due to premature ovulation?
Slow or sluggish temperature rises or a temperature shift that does not significantly rise above the coverline.
What percentages of infertility cases are due solely to the male factor?
30-50%
When analyzing male fertility, it is common to receive data on what?
- sperm quantity
- motility
- morphology
What is a normal quantity of sperm?
Over 15 million sperm per milliliter
What does motility indicate?
- Quantity of movement
- How fast they swim
- If they swim in a linear line
- If they moe at all
What does morphology indicate?
The sperm’s shape, size, and structure. Abnormally large or small heads, multiple heads, multiple tails, or other abnormalities that can interfere with proper function.
What isn’t commonly tested for sperm quality?
The sperm’s DNA. Sperm analysis may come back normal, yet DNA breaks or mutations in the sperm could still be a contributing factor behind male-factor infertility, genetic complications, and even miscarriage.
What is the most accurate test for assessing sperm DNA quality?
Sperm Chromatin Structure Assay (SCSA)
Wht factors should be looked at if all routine fertility tests come back “normal”?
- Structural abnormalities
- Anovulation
- HP Axis Dysfunction
- Sperm & Egg/Follicle Quality
- Chromosomal and embryonic abnormalities
- Genetic mutations and predispositions
- Chronic stress, heightened inflammation, chronic immune system activation
- Micronutrient Deficiencies
What can lead to structural abnormalities?
- Scar tissue build up in the uterine tubes or uterus (Asherman’s syndrome) or as a consquence of STIs like chlamydia
- MRKH syndrome which a woman is born with an underdeveloped or missing uterus
- Cervical Stenosis which leads to a narrowed or closed cervix
There needs to be a balanced level of BLANK to grow the endometerial lining to the preferred thickness.
Estrogen.
Estrogen excess is associated with the growth of BLANK which may all hinder fertility and pregnancy chances
- Cysts
- Fibroids
- Endometriosis
Where does progesterone get its name?
Pro-gestation! It’s one of the most important hormones when it comes to sustaining a pregnancy.
What does progesterone do?
Slows the pulsation of GnRH from the hypothalamus, telling the ovaries to stop growing follicles and producing estrogen, which inhibits the endometrial lining from becoming too thick.
Also helps to hold the endometrial lining intact so that it doesn’t shed prematurely if an egg does implant.
Why is it important to have a healthy corpus luteum for pregnancy?
Up until the 8-9th week, the corpus luteum is the primary source of progesterone production until the placenta forms and can take over.
Luteal phase deficiency (<10 luteal phase days) due to low BLANK levels can further hinder fertility as it takes roughly 5-6 days for the egg to travel down the uterine tubes into the uterus and 7-10 days for the uterine lining to become receptive to implantation. If the endometrial lining were to shed before that point, it may result in a failed pregnancy.
Low progestrone
Progesterone promotes BLANK, which stimulates the production of thyroid hormone.
Thermogenesis
Adequate BLANK plays a role in maintaining proper body temperature within the luteal phase.
Thyroid hormone
What does adequate thyroid hormone do in maintaining a proper body temp during the luteal phase?
Helps to sustain and “incubate” an embyro once implanted.
Womenw ith hypothyroidism tend to have lower BBTs than average, which may affect proper embyronic development. Due to the lower than optimal body temperatures, many early miscarriages may be linked to undiagnoses hypothyroid conditions.
Thyroid hormone is necessary for proper BLANK hormone production and metabolism.
Steroid. So hypothyroidism may play a role in various sex hormone imbalances that could also impact fertility and conception changes.
Poor egg quality and BLANK health often go hand in hand, as in order to ovulate properly, a woman has to develop a fully funcitonal follicle.
Follicle
Often these issues happen within the preantral stages of follicle development
Can those with SNPS (single nucleotide polymorphisms in MTHFR or other genes support their genetic health and expression through nutrition and lifestyle, often going on to have healthy pregnancies?
Yes
Chronic stress, heightened inflammation, and chronic immune system activation such as with autoimmune disease, impaired intestinal integrity, and insuling resistance may factor into BLANK and BLANK as well as BLANK and BLANK?
Poor egg quality and follicle development as well as unfavorable environment for implantation and embryonic growth.
What is the reason why women with chronic immune system activation, such as autoimmune conditions and gut infections may have a more difficult time conceiving or carrying to term?
During pregnancy, the immune system shifts into being TH2 dominant, which is not associated with inflammation.
This shift plays a role in preventing the immune system from attacking the tissues of the growing fetus.
Progesterone also plays a role in mildly suppressing the immune system, helping to ensure that the body doesn’t reject the newly implanted embryo.
How can micronutrients play an important role in ovulatory health?
- They can either directly support the act of follicle development and ovulation OR
- They can serve as antioxidants, supporting a healthy oxidative environment for ovulation to occur.
Micronutrient deficinecies and/or imbalances may hinder both of these important processes.
How does zinc deficiency impact ovulation and fertility outcomes?
- Zinc helps support FSH production and is necessary for antral follicle development
- Deficiency can result in poor follicle and corpus luteaum health. This can impact the quality and quantity of progesterone, which can impact one’s fertility.
- Zinc helps facilitate embryogenesis and development
- Zinc is necessary for sperm count, density, motility, morphology, and viability, as well as seminal pH.

What is hypochlorhydria?
A deficiency of stomach acid
Zinc absorption can be greatly hindered in the presence of BLANK so if your client experiences digestive disturbances in addition to ovulatory or fertility complications, it is possible they may be deficient in zinc.
Hypochlorhydria
a deficiency of stomach acid
Zinc may not be recommended in high dosages for those who experience low BLANK levels?
Estrogen, as zinc can act as an aromatase inhibitor, potentially lowering estrogen levels further.
What is aromatase?
The enzyme responsible for the convesrion of androgens to estrogen in many tissues, including the goands.
Iron deficiency and anemia issues can lead to poor BLANK?
Poor ovulatory function, as iron is a necessary component of heme and hemoglobin.
