Infertility And Gestational Diabetes Flashcards
Reproductive structures that produce and release female gametes and sex hormones like estrogen and progesterone
Ovaries
Tiny, sac-like structures that each hold a single primary oocyte
Ovarian follicles
The process of egg production
Oogenesis
Hormones involved in the reproductive cycle
GnRH (released by hypothalamus), FSH & LH (released by anterior pituitary)
Male gonads responsible for making sperm and the androgen hormone testosterone
Testicles
Why are the testicles outside of the body?
For proper spermatogenesis (sperm are very sensitive to temperature)
An inability to conceive after one year of regular, unprotected sexual intercourse
Primary infertility
Inability to conceive after carrying a child to viability (at least 20 weeks)
Secondary infertility
Why is a comprehensive history and physical necessary when assessing for infertility?
Because ANY disruption in the process of conception may cause infertility
The nurse should refer for evaluation after _____ of failure to conceive
1 year
The nurse should refer for evaluation after _____ of failure to conceive for HIGH RISK patients
6 months
Maternal age >___ poses a risk for infertility
35
Genetic conditions that may cause a higher risk of infertility
Turner or Down Syndrome
Examples of fertility-lowering diseases
Endometriosis, Polycystic Ovarian Disease
What are the 6 essential components of female fertility?
Favorable cervical mucus, clear passage between cervix and tubes, patent tubes with normal motility, ovulation and release of ova, no obstruction between ovary and tubes, endometrial preparation
Lack of ovulation
Anovulation
Syndrome by which no oocytes are retrieved from the mature follicle after ovulation induction in IVF cycles
Empty follicle syndrome
Syndrome resulting from trauma to the endometrium in which curettage scar tissue bonds together and decreases the volume of the uterine cavity
Asherman’s syndrome
Female CNS/Endocrine factors that can contribute to infertility
Excessive weight loss, thyroid dysfunction, stress, inadequate estrogen/progesterone levels
What are the 4 essential components of male fertility?
Normal semen analysis, unobstructed genital tract, normal genital tract excretions, ejaculate deposited at the cervix
What is often the FIRST diagnostic test for male infertility because it is least invasive?
Semen analysis
How does obesity contribute to male infertility?
Inhibits adequate vaginal penetration
Oligospermia is classified as <___ mil/mL
20
Infections that affect sperm production and maturation factors
Gonorrhea, Chlamydia, Orchitis
Diseases that affect sperm production and maturation factors
Mumps infection after puberty
Examples of trauma that affect sperm production and maturation factors
Vasectomy, riding mountain bikes
Environmental factors that affect sperm production and maturation
Radiation, smoking, alcohol, drug use, malnutrition, stress, constrictive underclothing
Factors that can alter the shape or motility of sperm
Infections (prostatitis, chlamydia), polyspermia, asthenospermia
Loss or reduction of sperm motility
Asthenospermia
Ejaculation into the bladder
Retrograde ejaculation
Initial infertility assessment factors
Ovarian function, cervical mucus, sperm adequacy, tubal patency, pelvic organ condition
Female infertility assessment
Age (35+), history (medical, surgical, obstetric, gynecologic, sexual), occupation/environment risk, nutrition status, substance use
Male infertility assessment
History (medical, surgical, sexual), substance use, occupation/environment risk
Tests/procedures that determine when/if a female is ovulating
Basal body temp. Charts, urine ovulation predictor, endometrial biopsy, transvaginal ultrasound
Patient education for measuring basal body temperature
Take temp each morning before rising
Basal body temperature BEFORE ovulation
Temp drop 0.2 F 24-36 hours before ovulation
Basal body temperature AFTER ovulation
Temp rises 0.5-1.0 F 24-72 hours after ovulation due to progesterone released by the corpus luteum
Urine ovulation predictor identifies
LH surge prior to ovulation
Procedure that checks the endometrial response to hormonal cycle to ensure proper prep for implantation
Endometrial biopsy
What female hormones are analyzed for the diagnosis of infertility?
Prolactin, progesterone, estrogen, FSH, LH, thyroid
Female infertility diagnostic procedure that uses radiopaque dye to visualize fallopian tube patency and flushes debris or adhesions
Hysterosalpingography (HSG)
Nursing consideration for HSG
Assess for iodine/seafood allergy
Radiographic procedure that examines internal structures of the uterus
Hysteroscopy
Female infertility diagnostic for patients with endometriosis consisting of gas insufflation to visual internal organs and remove endometrial deposits while the patient is under general anesthesia
Laparoscopy
Infertility diagnostic in which patients have sex at a particular time followed by analysis of mucus and sperm interaction
Postcoital test
Semen analysis examines
Number, morphology, and motility
Semen analysis sample should be obtained after ___ days of abstinence and ___ separate analysis should be done
3; 2
Infertility diagnostic that assesses for antisperm antibodies and enzymatic defect (which prevents sperm from penetrating ova)
Sperm Penetration Assay (SPA) or Hamster Test
Male infertility diagnostic that visualizes testes transrectally to assess ejaculatory ducts, seminal vesicles, and vas deferens
Ultrasonography
Testicular biopsy checks for
Endocrine issues, blockage, or non-production
Male infertility diagnostic consisting of an X-ray of veins after administration of dye and assesses blood flow to scrotum
Venography
Postcoital mucus examination timing
Before ovulation, 8-12 hours after intercourse
Cervical mucus characteristics before ovulation
Raw egg white
Cervical mucus characteristics after ovulation
Thick, cloudy, pasty
Infertility treatment modalities education
Change in lifestyle (drugs, diabetes control), sexual techniques, timing of sexual intercourse
Infertility medications teaching
Must be taken on a regular schedule
Medication that induces ovulation by stimulating GnRH, LH, and FSH
Clomiphene citrate (Clomid)
Patient education for Clomid
Take for 5 consecutive days, starting with lowest dose
Medication that stimulates follicular development and blocks conversion to estrogen, therefore stimulating FSH and GnRH
Letrozole (Femara)
Patient education for Femara
Take for 5 consecutive days
Clomid and Femara work by
Increasing ovulation
Medication that supports ovulation by managing hyperinsulinemia in patients with PCOS
Metformin
Too much insulin may prevent
Ovulation
Assisted Reproductive Technology that places prepared sperm at cervical OS or in uterus
Intrauterine Insemination (IUI)
Therapeutic donor insemination may be useful for
Chromosomal concerns
Individual that is inseminated with semen and carries fetus until birth
