Infertility 1 in 8 couples affected Definition: Failure to conceive after 1 year of regular, unprotected intercourse Earlier evaluation is recommended if: Women >35 years old Irregular menses History of Pelvic Inflammatory Disease Endometriosis Men with risk factors (e.g. testicular surgery, abnormal semen analysis)

Critical Factors Affecting Fertility Oocytes Sperm Uterus Fallopian Tubes
Critical Factors Affecting Fertility Oocytes – FSH / Estradiol Ovarian Reserve Age – Quality FSH – Quantity Ovulatory Dysfunction Midluteal Progesterone – Ovulation TSH & Prolactin Sperm Uterus Fallopian Tubes
Evaluation of Ovulation Basal BodyTemperature – Poor Sensitivity Urinary LH kits start 2-3 days before surge is expected ovulation is 24-48 hrs later Midluteal Progesterone > 3 ng/ml shows evidence of ovulation > 10 ng/ml shows evidence of “good” ovulation 1 wk before menses is best
Oocyte Attrition 20 weeks in utero – 6 to 7 million Birth – 1 million Menarche – 300,000 to 400,000 37yr – 25,000 Menopause – 1,000
Ovarian Reserve is the number and quality of eggs in the ovaries
Quantification of Ovarian Reserve Age FSH Inhibin B, AMH Basal antral follicle count Ovarian volume Clomid challenge test FSH stimulation test Serum U/S Response to Stimulation
Age and Female Fertility Peak fertility age 20-24 Decreases some until age 30-32 Declines rapidly after 435

Critical Factors Affecting Fertility Oocytes Sperm – Semen Analysis Volume Concentration Motility Morphology Uterus Fallopian Tubes
Microscopic evaluation Semen Analysis The gross examination Microscopic evaluation Appearance (opaque) Volume (2-6 mL) Viscosity (liquefaction, 1 hr) pH value (7-8) Count ( 20 million/mL) Motility (>50%) Morphology ( 30 % normal) (World Health Organization Criteria) Other Tests • Sperm Chromatin Structure Assay / TUNEL • Sperm DNA Decondensation • Sperm Penetration Tests • Postcoital Test
Semen Analysis Should be ordered in any couple who presents for infertility Repeat if abnormal Ideally there should be more than 10 million Normal Motile Sperm 5-20 million – insemination indicated <1 million – ICSI indicated
Sperm Attrition
Additional Male Evaluation FSH, LH Testosterone Prolactin, TSH Karyotype Y Chromosome Microdeletion Urology referral – evaluation for varicocele (ultrasound) Freeze viable sperm if undergoing a diagnostic biopsy
Critical Factors Affecting Fertility Oocytes Sperm Uterus – HSG or SHG Fibroids Polyps Synechiae Fallopian Tubes
Uterine Evaluation Ultrasound Sonohysterogram (saline ultrasound) Hysterosalpingogram MRI Hysteroscopy
Ultrasound Evaluates uterus, adnexa and occasionally the fallopian tubes May be helpful in diagnosing uterine abnormalities
Sonohystogram (SHG) Concurrent saline distention of the uterine cavity and vaginal ultrasonography
Hysterosalpingogram (HSG)
Hysteroscopy Allows direct evaluation the uterine cavity Concurrently diagnose and treat
Critical Factors Affecting Fertility Oocytes Sperm Uterus Fallopian Tubes – HSG Patent vs. Occluded Proximal vs. Distal Occlusion Potential therapeutic effect
Hysterosalpingogram (HSG)
MRI In Lieu of Surgery In Preparation for Surgery Non-surgically evaluate the uterus to differentiate between various forms of congenital anomalies In Preparation for Surgery To map fibroids prior to surgery Help diagnose adenomyosis
Laparoscopy Allows direct visualization of the pelvic anatomy. Can evaluate endometriosis, adhesions, uterine abnormalities or ovarian masses Chromotubation use of a dilute solution of blue dye instilled through the cervix can demonstrate tubal patency or distal tubal occlusive disease. Surgically correct the disease process
Laparoscopy
Laparoscopy Peritubal Adhesions Lysis of Adhesions and Chromotubation
Laparoscopy Resection of Hydrosalpinx
Treatment - Oocytes Controlled Ovarian Hyperstimulation Long Protocol Antagonist Microdose Flare Ovulation Induction Clomid hMG or FSH Clomid + FSH
Treatment - Sperm Intrauterine Insemination (IUI) – place the washed sperm at the top of the uterus near the opening of the fallopian tubes Intracytoplasmic Sperm Injection (ICSI) – directly inject each sperm into each egg
Treatment - Uterus Hormonal – estrogen supplementation to increase endometrial thickness Surgical – remove polyps, fibroids, scar tissue, septum, etc.
Treatment – Fallopian Tubes Surgical – correct tubal disease, endometriosis, scar tissue OI & IUI – if unilateral tubal obstruction IVF – for bilateral tubal disease
Unexplained Infertility Normal Semen analysis, evidence of ovulation, normal uterus, tubes are open Surgery-Laparoscopy-to exclude endometriosis/adhesions Consider the addition of hysteroscopy Stepwise empiric treatment of OI & IUI and IVF
When to Use Assisted Reproductive Technology (ART) Neither fallopian tube is patent Severe endometriosis Severe male factor infertility Unexplained infertility After medical treatment has failed For genetic indications-PGD

Embryo transfer Embryos are inserted into the uterus Embryo
Preimplantation Genetic Diagnosis a procedure that allows embryos to be tested for genetic disorders before they enter the uterus and before pregnancy has begun Thornhill et al, JMD 2002
