Structures infertility workup with ovarian reserve testing, semen analysis, and treatment algorithms. Use when evaluating infertility, ordering fertility workup, or managing reproductive planning.
Structures infertility workup with ovarian reserve testing, semen analysis, tubal assessment, and stepped treatment algorithms per ASRM and ACOG Practice Bulletin No. 217.
Why This Skill Exists
Infertility — defined as failure to conceive after 12 months of unprotected intercourse (or 6 months if female partner is ≥ 35) — affects approximately 12–15% of couples. The American Society for Reproductive Medicine (ASRM) recommends a systematic, simultaneous evaluation of both partners, as male factor contributes to approximately 40–50% of infertility cases (sole male factor ~20%, combined male + female ~20–30%). Delays in evaluation lead to age-related decline in ovarian reserve, diminishing treatment success.
ACOG Practice Bulletin No. 217 (Infertility Workup for the Women's Health Specialist) outlines the standard evaluation components. This skill ensures a complete, concurrent evaluation of ovulatory function, tubal patency, uterine anatomy, ovarian reserve, and male factor — then maps findings to the appropriate treatment tier.
Checkpoint A: Pre-Draft Intake (Mandatory)
Duration of infertility — months of unprotected intercourse? Primary (never conceived) or secondary (prior pregnancy)? (Default: from history)
相關技能
Female partner age — critical for prognosis and urgency of evaluation. (Default: from demographics)
Coital frequency and timing — intercourse frequency and relationship to ovulation? Use of ovulation prediction kits? (Default: from history)
Menstrual history — cycle length, regularity, signs of ovulatory dysfunction (oligomenorrhea, amenorrhea)? (Default: from menstrual calendar)
Obstetric and gynecologic history — prior pregnancies (with any partner), ectopic, PID, endometriosis, uterine surgery? (Default: from history)
Male partner history — prior paternity, testicular surgery, varicocele, medications, toxin exposure, ejaculatory dysfunction? (Default: from male partner history)
Medical comorbidities — thyroid disease, PCOS, hyperprolactinemia, DM, eating disorders, excessive exercise? (Default: from problem list)
Social factors — tobacco, alcohol, marijuana, occupation, environmental exposures? (Default: from social history)
Evaluate both partners simultaneously — do not complete the full female workup before ordering a semen analysis; male factor is present in 40–50% of cases.
Age drives urgency — women ≥ 35 should be referred after 6 months; women ≥ 40 warrant immediate evaluation.
Letrozole is first-line for PCOS ovulation induction — the NICHD PPCOS II trial demonstrated higher live birth rates with letrozole vs. clomiphene.
Do not skip ovarian reserve testing — even in young patients, diminished reserve changes the treatment approach and timeline.
Document the AFC method — report bilateral antral follicle count with probe frequency and technique for reproducibility.
Recognize when to refer — bilateral tubal occlusion, severe male factor, diminished ovarian reserve, and age ≥ 38 with > 6 months of failed first-line treatment should be referred to a reproductive endocrinologist.
Counsel on realistic expectations — per-cycle success rates for IUI are 10–20%, and IVF success rates are age-dependent (age < 35: ~50% live birth per transfer; age 40–42: ~15%).
Address lifestyle factors — BMI optimization (ideal 19–25), smoking cessation, alcohol limitation, and caffeine < 200 mg/day all impact fertility.
