Infertility

1. Infertility

2. Infertility • The inability to conceive following unprotected sexual intercourse • 1 year (age < 35) or 6 months (age >35) Normally a fertile couple has approximately a 20 % chance of conception in each ovulatory cycle

3. Infertility • Primary infertility • a couple that has never conceived • Secondary infertility • infertility that occurs after previous pregnancy regardless of outcome

4. Requirements for Conception • normally developed reproductive tract in both the male and female partner • normal functioning of an intact hypothalamic-pituitary-gonadal axis supports gametogenesis (the formation of sperm and ova). • timing of intercourse • Unblocked tubes that allow sperm to reach the egg • The sperms ability to penetrate and fertilize the egg • Implantation of the embryo into the hormone-prepared endometrium • Finally a healthy pregnancy

5. Infertility. Statistic • A female factor (ovulatory dysfunction, pelvic factor) is in approximately 50% • A male factor (sperm and semen abnormalities) is in approximately 35% • Unexplained factors and causes (e.g., coital techniques) related to both partners are in approximately 15%

6. Causes for infertility

7. Cause of Female Infertility • CONGENITAL OR DEVELOPMENTAL FACTORS • Abnormal external genitals • Absence of internal reproductive structures • HORMONAL FACTORS • Anovulation-primary • Pituitary or hypothalamic hormone disorder Adrenal gland disorder • Congenital adrenal hyperplasia • Anovulation-secondary • Disruption of hypothalamic-pituitary-ovarian axis Early menopause • Amenorrhea after discontinuing OCP Increased prolactin levels • TUBAL/PERITONEAL FACTORS • Absence of fimbriated end of tube Tubal motility reduced • Absence of a tube Inflammation within the tube Tubal adhesions • UTERINE FACTORS • Developmental anomalies • Endometrial and myometrial tumors • Asherman syndrome (uterine adhesions or scar tissue)

Length of time required to initiate each pregnancy • C. Complication of pregnancy • D. Duration of lactation • 4. Gynecologic: detailed menstrual history • 5. Previous tests and therapy of infertility • 6. Medical: general (chronic&hereditary disease), medication, family problem, sexual development, galactorrhea • 7. Surgical: abdominal or pelvic surgery

21. 1. Follicular development, ovulation, and luteal develop­ment are supportive of pregnancy: • a. Basal body temperature (presumptive evidence ofovulatory cycles) is biphasic, with temperature eleva­tion that persists for 12 to 14 days before menstruation • b. Cervical mucus characteristics change appropriatelyduring phases of menstrual cycle • c. Laparoscopic visualization of pelvic organs verifiesfollicular and luteal development • 2. The luteal phase is supportive of pregnancy: • a. Levels of plasma progesterone are adequate • b. Findings from endometrial biopsy samples are con­sistent with day of cycle • 3. Cervical factors are receptive to sperm during expectedtime of ovulation: • a. Cervical os is open • b. Cervical mucus is clear, watery, abundant, and slip­pery and demonstrates good spinnbarkeit and ar­borization (fern pattern) • c. Cervical examination does not reveal lesions or in­fections • d. Postcoital test findings are satisfactory (adequatenumber of live, motile, normal sperm present in cer­vical mucus) • e. No immunity to sperm demonstrated • 4. The uterus and uterine tubes are supportive of preg­nancy: • a. Uterine and tubal patency are documented by • Spillage of dye into peritoneal cavity • Outlines of uterine and tubal cavities of adequatesize and shape, with no abnormalities • b. Laparoscopic examination verifies normal develop­ment of internal genitals and absence of adhe­sions, infections, endometriosis, and other lesions • 5. The male partner's reproductive structures are normal: • a. No evidence of developmental anomalies of penis,testicular atrophy, or varicocele (varicose veins onthe spermatic vein in the groin) • b. No evidence of infection in prostate, seminal vesi­cles, and urethra • c. Testes are more than 4 cm in largest diameter • 6. Semen is supportive of pregnancy: • a. Sperm (number per milliliter) are adequate in ejacu­late • b. Most sperm show normal morphology • c. Most sperm are motile, forward moving • d. No autoimmunity exists • e. Seminal fluid is normal

22. Abnormalities of Spermatogenesis

23. Normal • Sperm made in seminiferous tubules • Travel to epididymis to mature

24. Normal • Sperm exit through vas deferens • Semen produced in prostate gland, seminal glands, cowpers glands • Sperm only 5% of ejaculation • Sperm can live 5-7 days

25. Semen Analysis (SA) • Obtained by masturbation • Provides immediate information • Quantity • Quality • Density of the sperm • Morphology • Motility • Abstain from coitus 2 to 3 days • Collect all the ejaculate • Analyze within 1 hour • A normal semen analysis excludes • male factor 90% of the time

26. Normal Values for SA Volume Sperm Concentration Motility Viscosity Morphology pH WBC • 2.0 ml or more • 20 million/ml or more • 50% forward progression 25% rapid progression • Liquification in 30-60 min • 30% or more normal forms • 7.2-7.8 • Fewer than 1 million/ml

27. Causes for Abnormal SA Abnormal Count • No sperm • Klinefelter’s syndrome • Sertoli only syndrome • Ductal obstruction • Hypogonadotropic-hypogonadism • Few sperm • Genetic disorder • Endocrinopathies • Varicocele • Exogenous (e.g., Heat)

28. Continues: causes for abnormal SA • Abnormal Morphology • Varicocele • Stress • Infection (mumps) • Abnormal Motility • Immunologic factors • Infection • Defect in sperm structure • Poor liquefaction • Varicocele • Abnormal Volume • No ejaculate • Ductal obstruction • Retrograde ejaculation • Ejaculatory failure • Hypogonadism • Low Volume • Obstruction of ducts • Absence of vas deferens • Absence of seminal vesicle • Partial retrograde ejaculation • Infection

29. Causes for male infertility • 42% varicocele • repair if there is a low count or decreased motility • 22% idiopathic • 14% obstruction • 20% other (genetic abnormalities)

30.

31. Evaluation of Abnormal SA • Repeat semen analysis in 30 days • Physical examination • Testicular size • Varicocele • Laboratory tests • Testosterone level • FSH (spermatogenesis- Sertoli cells) • LH (testosterone- Leydig cells) • Referral to urology

32. Evaluation of Ovulation

33. Female Reproductive System • Ovaries • Two organs that produce eggs • Size of almond • 30,000-40,000 eggs • Eggs can live for 12-24 hours

34. Menstruation • Ovulation occurs 13-14 times per year • Menstrual cycles on average are Q 28 days with ovulation around day 14 • Luteal phase • dominated by the secretion of progesterone • released by the corpus luteum • Progesterone causes • Thickening of the endocervical mucus • Increases the basal body temperature (0.6° F) • Involution of the corpus luteum causes a fall in progesterone and the onset of menses

36. Ovulation • A history of regular menstruation suggests regular ovulation • The majority of ovulatory women experience • fullness of the breasts • decreased vaginal secretions • abdominal bloating • Absence of PMS symptoms may suggest anovulation • mild peripheral edema • slight weight gain • depression

38. Diagnostic studies to confirm Ovulation • Basal body temperature • Inexpensive • Accurate • Endometrial biopsy • Expensive • Static information • Serum progesterone • After ovulation rises • Can be measured • Urinary ovulation-detection kits • Measures changes in urinary LH • Predicts ovulation but does not confirm it

39. Basal Body Temperature • Excellent screening tool for ovulation • Biphasic shift occurs in 90% of ovulating women • Temperature • drops at the time of menses • rises two days after the lutenizing hormone (LH) surge • Ovum released one day prior to the first rise • Temperature elevation of more than 16 days suggests pregnancy

41. Serum Progesterone • Progesterone starts rising with the LH surge • drawn between day 21-24 • Mid-luteal phase • >10 ng/ml suggests ovulation

42. Salivary Estrogen: TCI Ovulation Tester- 92% accurate

43. Add Saliva Sample

46. Non-Ovulatory Saliva Pattern
