Transcript

  • 1. Fertility &Infertility
  • 2. Group Members Matee Ullah Shabana Qureshi Saddam Imtiaz Wilson Chaman Sajjid Yasin
  • 3. Objectives• Significance of topic• Define fertility and infertility• Requirements for Conception• Primary and Secondary infertility• Causes for infertility• Diagnosis and management of infertility• Summarization
  • 4. Significance:It has been estimated that 15-20% of couples attempting to achieve pregnancy are unable to do so. A male factor is contributory in more than 50% of couples presenting for fertility evaluation.The significance of this presentation is to make aware first the healthcare providers, so that they may able to educate the couples.
  • 5. Fertility:-Ability to conceive
  • 6. Infertility• The inability to conceive following unprotected sexual intercourse for two year. • Affects 15% of reproductive couples • 6.1 million couples • Men and women equally affected
  • 7. Requirements for Conception• Production of healthy egg and sperm• Unblocked tubes that allow sperm to reach the egg• The sperms ability to penetrate and fertilize the egg• Implantation of the embryo into the uterus• Finally a healthy pregnancy
  • 8. Infertility• Reproductive age for women• Generally 15-44 years of age• 20% of women have their first child after age 30• 1/3 of couples over 35 have fertility problems • Ovulation decreases • Health of the egg declines• With the proper treatment 85% of infertile couples can expect to have a child
  • 9. Infertility• Primary infertility • a couple that has never conceived• Secondary infertility • infertility that occurs after previous pregnancy regardless of outcome
  • 10. Causes for infertility• Male • Female • Abnormal sperm count, • Age morphology or motility • Stress • Low testosterone level • Over/underweight • Life style factor • Tobacco (drugs, smoking, heat) • STD’s • Infection-GUT • Health problems • Obstruction • Testicular cancer • Cryptorchidism • Radiation/Chemotherapy • Age • Vericocele • Hydrocele • Hypospadias
  • 11. Causes of Infertility• Unexplained (10%-20%)• Anovulation (10-20%)• Anatomic defects of the female genital tract (30%)• Abnormal spermatogenesis (40%)
  • 12. Evaluation of the Infertile couple• History and Physical exam• Semen analysis• Thyroid and prolactin evaluation• Determination of ovulation • Basal body temperature record • Serum progesterone • Ovarian reserve testing• Hysterosalpingogram
  • 13. Hysterosalpingogram• An X-ray that evaluates the internal female genital tract • architecture and integrity of the system• Performed between the 7th and 11th day of the cycle• Diagnostic accuracy of 70%
  • 14. Abnormalities of Spermatogenesis
  • 15. Male Factor• 40% of the cause for infertility• Sperm is constantly produced by the germinal epithelium of the testicle• Sperm production is thermoregulated• 1 F less than body temperature• Both men and women can produce anti-sperm antibodies which interfere with the penetration of the cervical mucus
  • 16. Semen Analysis (SA)• Obtained by masturbation• Provides immediate information• Quantity• Quality• Density of the sperm• Abstain from coitus 2 to 3 days• Collect all the ejaculate• Analyze within 1 hour
  • 17. Normal Values for SAVolume – 2.0 ml or moreSperm Concentration – 20 million/ml or moreMotility – 75%Viscosity – Liquification in 30-60 minMorphology – 30% or more normalpH formsWBC – 7.2-7.8 – Fewer than 1 million/ml
  • 18. Evaluation of Ovulation
  • 19. Menstruation • Ovulation occurs 13-14 times per year • Menstrual cycles on average are 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
  • 20. 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
  • 21. Diagnostic studies to confirmOvulation • Basal body temperature • Serum progesterone • Inexpensive • After ovulation rises • Accurate • Can be measured • Endometrial biopsy • Urinary ovulation-detection kits • Expensive • Measures changes in • Static information urinary LH • Predicts ovulation but does not confirm it
  • 22. Anovulation
  • 23. Anovulation Symptoms Evaluation* • Irregular menstrual • Follicle stimulating cycles hormone • Amenorrhea • Lutenizing hormone • Hirsuitism • Thyroid stimulating hormone • Acne • Prolactin • Galactorrhea • Total testosterone • Increased vaginal secretions*Order the appropriate tests based on the clinical indications
  • 24. Sperm transport, Fertilization, &Implantation • The female genital tract is not just a conduit • facilitates sperm transport • cervical mucus traps the coagulated ejaculate • the fallopian tube picks up the egg • Fertilization must occur in the proximal portion of the tube • the fertilized oocyte cleaves and forms a zygote • enters the endometrial cavity at 3 to 5 days • Implants into the secretory endometrium for growth and development
  • 25. Treatment of the Infertile Couple
  • 26. Inadequate Spermatogenesis• Eliminate alterations of thermoregulation• Clomiphene citrate is occasionally used for induction of spermatogenesis • 20% success• In vitro fertilization may facilitate fertilization• Artificial insemination with donor sperm is often successful
  • 27. Anovulation• Restore ovulation• Administer ovulation inducing agents• Clomiphene citrate• Antiestrogen • Combines and blocks estrogen receptors at the hypothalamus and pituitary causing a negative feedback • Increases FSH production • stimulates the ovary to make follicles
  • 28. Superovulatory Medications• Gonadotropins- FSH (e.g. pergonal) can be administered intramuscularly • This is usually given under the guidance of someone who specializes in infertility• This therapy is expensive and patients need to be followed closely• Adverse effects • Hyperstimulation of the ovaries • Multiple gestation
  • 29. Emotional and Educational Needs• Disease of couples, not individuals• Feelings of guilt• Where to go for information?• Options• Feelings of frustration and anger• Support groups
  • 30. WHO WILL SUMMARIZE
  • 31. Summary• Infertility is common problem• Infertility is a disease of couples• Infertility should be evaluated after one year of unprotected intercourse.• History and Physical examination usually will help to identify the etiology.• If patients fail the initial therapies then the proper referral should be made to a reproductive specialist.
