# Managing Fertility Evaluations 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) 1. **Duration of infertility** — months of unprotected intercourse? Primary (never conceived) or secondary (prior pregnancy)? (Default: from history) 2. **Female partner age** — critical for prognosis and urgency of evaluation. (Default: from demographics) 3. **Coital frequency and timing** — intercourse frequency and relationship to ovulation? Use of ovulation prediction kits? (Default: from history) 4. **Menstrual history** — cycle length, regularity, signs of ovulatory dysfunction (oligomenorrhea, amenorrhea)? (Default: from menstrual calendar) 5. **Obstetric and gynecologic history** — prior pregnancies (with any partner), ectopic, PID, endometriosis, uterine surgery? (Default: from history) 6. **Male partner history** — prior paternity, testicular surgery, varicocele, medications, toxin exposure, ejaculatory dysfunction? (Default: from male partner history) 7. **Medical comorbidities** — thyroid disease, PCOS, hyperprolactinemia, DM, eating disorders, excessive exercise? (Default: from problem list) 8. **Social factors** — tobacco, alcohol, marijuana, occupation, environmental exposures? (Default: from social history) ### Documents to Request - Prior fertility evaluation results (both partners) - Semen analysis report(s) - HSG or SHG reports - Ovarian reserve testing (AMH, day-3 FSH/estradiol, antral follicle count) - Thyroid function tests - Prolactin level - Prior operative reports (laparoscopy, hysteroscopy, tubal surgery) - Genetic testing results (karyotype, FMR1, carrier screening) - Partner medical records if available --- ## Step 1: Ovulatory Assessment Ovulatory dysfunction accounts for approximately 25–30% of female infertility. | Assessment Method | Timing | Interpretation | |---|---|---| | Menstrual history | Ongoing | Regular 24–35 day cycles strongly suggest ovulation | | Basal body temperature (BBT) | Daily | Biphasic pattern (0.2–0.5°C rise) confirms ovulation retrospectively | | Urine LH surge (OPK) | Mid-cycle | Positive predicts ovulation in ~24–36 hours | | Mid-luteal progesterone | Day 21 (or 7 days post-expected ovulation) | > 3 ng/mL confirms ovulation | | Endometrial biopsy | Luteal phase | No longer routinely recommended for dating; useful if endometrial pathology suspected | ### Ovulatory Dysfunction Workup | Condition | Testing | Findings | |---|---|---| | PCOS | Rotterdam criteria: 2 of 3 — oligo/anovulation, clinical/biochemical hyperandrogenism, polycystic ovarian morphology on US | Elevated free testosterone, DHEA-S; LH:FSH ratio > 2:1 (supportive but not required) | | Hypothalamic amenorrhea | FSH, LH, estradiol | Low/normal FSH, low LH, low estradiol | | Hyperprolactinemia | Prolactin | > 25 ng/mL — repeat; if persistent, consider MRI pituitary | | Thyroid dysfunction | TSH | Abnormal TSH → treat before fertility intervention | | Premature ovarian insufficiency | FSH, AMH, estradiol | FSH > 40 IU/L (× 2 samples), low AMH, low estradiol | --- ## Step 2: Ovarian Reserve Assessment Ovarian reserve predicts the quantity (not quality) of remaining oocytes and guides treatment intensity. | Test | Timing | Normal Values | Interpretation | |---|---|---|---| | **AMH** (anti-Müllerian hormone) | Any cycle day | 1.0–3.5 ng/mL | < 1.0 = diminished reserve; > 3.5 = possible PCOS | | **Day 3 FSH** | Cycle day 2–4 | < 10 IU/L | > 10 = diminished reserve; > 15 = poor prognosis | | **Day 3 estradiol** | Cycle day 2–4 | < 80 pg/mL | Elevated E2 with normal FSH may mask diminished reserve | | **Antral follicle count (AFC)** | Cycle day 2–5 (TVUS) | 10–20 total | < 5–7 = diminished reserve; > 20 = high responder / PCOS risk | Combine AMH + AFC for the most accurate reserve assessment. Document results with age-adjusted interpretation. --- ## Step 3: Tubal and Uterine Evaluation | Test | What It Assesses | Findings | |---|---|---| | **Hysterosalpingogram (HSG)** | Tubal patency, uterine cavity contour | Bilateral spill = patent tubes; filling defects = polyps/fibroids/synechiae; proximal vs. distal tubal occlusion | | **Saline infusion sonohysterogram (SIS)** | Uterine cavity detail | Polyps, submucosal fibroids, Asherman syndrome | | **Hysteroscopy** | Direct cavity visualization | Gold standard for intracavitary pathology — see and treat | | **Laparoscopy with chromopertubation** | Tubal patency + peritoneal disease | Reserve for suspected endometriosis, PID, or equivocal HSG | Uterine anomalies affecting fertility: - **Septate uterus** — most common anomaly associated with pregnancy loss; hysteroscopic septum resection improves outcomes - **Unicornuate uterus** — reduced cavity volume, associated with preterm delivery - **Asherman syndrome** — intrauterine adhesions from prior instrumentation; hysteroscopic lysis --- ## Step 4: Male Factor Evaluation Semen analysis is the cornerstone of male factor assessment. Per WHO 6th edition (2021) reference values: | Parameter | Lower Reference Limit (5th percentile) | |---|---| | Volume | ≥ 1.4 mL | | Sperm concentration | ≥ 16 million/mL | | Total sperm count | ≥ 39 million per ejaculate | | Progressive motility | ≥ 30% | | Total motility | ≥ 42% | | Normal morphology (strict Kruger) | ≥ 4% | - Abnormal semen analysis → repeat in 4–12 weeks (values fluctuate) - Persistently abnormal → urology referral for evaluation (hormonal — FSH, testosterone, prolactin; physical exam — varicocele; genetic — Y-microdeletion, karyotype if severe oligospermia < 5 million/mL) - Azoospermia → obstructive vs. non-obstructive classification; refer to reproductive urologist --- ## Step 5: Treatment Algorithm | Diagnosis | First-Line Treatment | Second-Line | Third-Line | |---|---|---|---| | **Ovulatory dysfunction (PCOS)** | Letrozole 2.5–7.5 mg CD 3–7 (superior to clomiphene per NICHD trial) | Clomiphene 50–150 mg CD 5–9; gonadotropins | IVF | | **Unexplained infertility** | Timed intercourse × 3–6 cycles → letrozole/clomiphene + IUI × 3 | Gonadotropins + IUI (up to 3 cycles) | IVF | | **Tubal factor (bilateral occlusion)** | IVF (bypass tubal disease) | Tubal surgery (selected cases with mild distal disease) | — | | **Male factor (mild-moderate)** | IUI with sperm wash (requires ≥ 5–10 million TMSC) | IVF | IVF-ICSI | | **Male factor (severe / azoospermia)** | IVF-ICSI with TESE/micro-TESE if needed | Donor sperm | — | | **Diminished ovarian reserve** | Aggressive stimulation → IVF | Donor oocytes | — | | **Endometriosis** | Surgical excision + spontaneous attempt × 6 months | IUI with controlled stimulation | IVF | --- ## Checkpoint B: Post-Draft Alignment (Mandatory) 1. **Are both partners evaluated** — ovulatory function, tubal patency, ovarian reserve, and semen analysis all addressed? 2. **Is ovarian reserve documented** with age-adjusted interpretation? 3. **Is the treatment recommendation matched** to the specific diagnosis? 4. **Are time-sensitive factors addressed** — female age, duration of infertility, and declining reserve? 5. **Is the referral to reproductive endocrinology documented** when indicated (e.g., bilateral tubal disease, DOR, severe male factor)? --- ## Quality Audit - [ ] Duration and type (primary vs. secondary) of infertility documented - [ ] Female partner age documented with prognostic implications noted - [ ] Ovulatory assessment completed (menstrual history + mid-luteal progesterone or OPK) - [ ] Ovarian reserve testing documented (AMH + AFC or day-3 FSH/E2) - [ ] TSH and prolactin documented - [ ] HSG or SIS performed and results documented - [ ] Semen analysis performed with WHO 6th edition reference values applied - [ ] Abnormal semen analysis repeated and/or urology referral documented - [ ] Uterine cavity evaluation completed - [ ] PCOS evaluation documented using Rotterdam criteria (if oligoovulation present) - [ ] Treatment plan documented with tier-appropriate recommendation - [ ] Genetic screening offered (carrier screening per ACOG, karyotype if indicated) - [ ] Pre-conception counseling documented (folate, weight optimization, substance cessation) - [ ] Timeline for treatment escalation documented --- ## Guidelines 1. **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. 2. **Age drives urgency** — women ≥ 35 should be referred after 6 months; women ≥ 40 warrant immediate evaluation. 3. **Letrozole is first-line for PCOS ovulation induction** — the NICHD PPCOS II trial demonstrated higher live birth rates with letrozole vs. clomiphene. 4. **Do not skip ovarian reserve testing** — even in young patients, diminished reserve changes the treatment approach and timeline. 5. **Document the AFC method** — report bilateral antral follicle count with probe frequency and technique for reproducibility. 6. **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. 7. **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%). 8. **Address lifestyle factors** — BMI optimization (ideal 19–25), smoking cessation, alcohol limitation, and caffeine < 200 mg/day all impact fertility.
