Fertility Facts Definition:unprotected sex for one year, not pregnant Frequency: 1 out of 6 couples in the US Responsibility: 35% female infertility 35% male 20% both 10% unknown Maternal Age USA 20-24 4.1% 30-34 9.4% 25-29 5.5% 35-39 19.7% 85% treated successfully Increase 1970-now-Why?
Ovulation disorders Tube/uterus blockage Cervix Endometriosis Other Sperm count and defects Erectile or ejaculation deficiency What can cause infertility?Unexplained-18%Female Male Intrinsic vs. Extrinsic, Environmental
More detail on female infertility • Ovulatory failure-polycystic ovarian syndrome (high androgen/estrogenlevels), resistant ovarian syndrome, gonadal dysgenesis • Impaired gamete/zygote transport-pelvic inflammatory disease, endometriosis • Implantation defects-progesterone low • Spontaneous abortion-chromosome abnormality
More detail on male infertility • Cryptorchidism-Why? • Chromosome disorders-gonadal dysgenesis • Obstructions • Gonadotropin deficiency Result in:Low sperm count, sperm of poor quality
Female Infertility Tests • For ovulation • Basal body temperature • Ovulation kit (LH surge) • Other hormone tests (steroids) • Post ovulatory block • Laparoscopy-fiber optic look • Hysterosalpingogram-dye • Post-coital /cervical mucous and sperm • Sperm antibodies • Endometrial biopsy
Laparoscopy Can find adhesions, structural abnormality, etc
Hysterosalpingogram Blocked tubes
Male Infertility Tests • Sperm count/motility • > 20 million sperm/ml • Check motility and morphology • >50% motile • >30% structurally normal • If low check LH and androgen levels • Testicular biopsy
Older, low tech treatments • Drug treatment for ovulation block • Intrauterine insemination • Tubal surgery • High tech Assisted Reproduction Technologies • IVF-in vitro fert and embryo transfer • GIFT-gamete intrafallopian tube transfer • ZIFT-zygote intrafallopian tube transfer • Intracytoplasmic sperm injection
First test-tube baby
Assisted Reproductive Technology • Estimate 1/100 births now • Around 40,000/year • Costs between $7,000 to 15,000 per attempt
Basic Steps in IVF • Ovary stimulation • Egg retrieval • Sperm retrieval-wash sperm • Fertilization • Embryo transfer • Progesterone
Start with more than 1 egg • Drugs used for ovary stimulation • Clomiphene (clomid)-anti-estrogen • hMG (pergonal)-menopausal gonadotropin (FSH and LH) • FSH-(metrodin) • GnRH • GnRH agonists (lupron)-FSH/LH first promoted, then inhibited • hCG-acts like LH In a single cycle, could take clomid, pergonal, hCG shot, then progesterone
Why transfer more than one embryo? • Increase the pregnancy rate • Leads to increased risk of multiple pregnancies • In future- Test embryos before transfer sHLA-G measure of embryo health
Modifications if tube not blocked Gametes mixed for GIFT
Additional twists • Surrogacy • Gestational • Egg donor plus gestational • Egg donor plus sperm donor plus gestational • Frozen embryos • Egg donors • Frozen eggs • Cloning
IVF Success Rates Stage Number of Women Cycle initiation 100 Ovulation 95 Oocyte retrieval 90 Fertilization 85 Embryo Transfer 70 Pregnancy 24 Birth 18
Risks of ART? • To woman • Overstimulation of ovary syndrome • Multiple pregnancies • Risk of ovarian cancer (clomid, pergonal) • To baby • ICSI associated with problems (XYY)
Discussion questions-what treatment(s) would you select given the following: • Male with low sperm count • 30 year-old female not ovulating • 40 year-old female not ovulating • Undiagnosed infertility
