Evaluating the Infertile Couple: A Structured First-Visit Workup for General Practice
Quick Answer A structured infertility workup at the first visit evaluates both partners simultaneously — not the woman first and the man if she’s “normal.” Male factor accounts for approximately 40–50% of infertility presentations. The core first-visit assessment covers: female — menstrual history, ovulation status (LH surge, Day 21 progesterone, ultrasound), ovarian reserve (AMH or Day 2-3 FSH), and uterine/tubal cavity assessment; male — structured semen analysis interpreted against WHO 2021 reference values. Investigations can typically be initiated before a formal specialist referral is made. Referral thresholds vary by duration of infertility, female age, and findings — this article covers each in a structured format. Most Indian clinical content on infertility focuses exclusively on the woman. Investigations are ordered for her, imaging is done for her, and the history is taken almost entirely about her cycles. The male partner receives a semen analysis only if her evaluation comes back normal — or sometimes not at all if she has an identifiable diagnosis like PCOS or fibroids. This approach is clinically wrong in approximately half of all infertility presentations. Male factor contributes to infertility in 40–50% of couples — either as the sole cause or in combination with a female factor. A workup that doesn’t evaluate the male partner at the first visit is missing the cause of infertility in every other case. This article sets out a structured first-visit infertility workup that evaluates both partners systematically, covers the key investigations, sets realistic referral thresholds, and includes the commonly missed elements of a complete assessment.

This 12-month threshold applies to women under 35 years of age. For women aged 35 or older, the threshold for investigation shortens to 6 months — because ovarian reserve declines with age and delay reduces the available treatment window. Some presentations justify earlier investigation regardless of duration: Known or suspected ovulatory dysfunction (oligomenorrhoea, amenorrhoea) Known or suspected tubal factor (previous PID, ectopic pregnancy, pelvic surgery) Known uterine pathology (fibroids, previous uterine surgery, Asherman’s syndrome) Known or suspected male factor (previous testicular surgery, mumps orchitis, azoospermia) Female age ≥38 — do not wait 6 months, investigate immediately The female partner workup History — what to cover systematically A structured infertility history covers: duration of infertility and whether this is primary or secondary; menstrual cycle pattern (cycle length, regularity, flow, dysmenorrhoea); previous pregnancies and their outcomes; contraceptive history (including IUD use and duration); previous gynaecological procedures (D&C, hysteroscopy, laparoscopy, Caesarean section); symptoms of ovulatory dysfunction (intermenstrual spotting, cycle irregularity, galactorrhoea); and symptoms of PCOS, thyroid disease, or hyperprolactinaemia. Ovulation assessment Regular cycles of 25–35 days occurring consistently are a reasonable clinical indicator of ovulation in most women — but not a guarantee. Formal ovulation assessment options: Method Timing Interpretation Limitation Mid-luteal progesterone Day 21 in 28-day cycle; 7 days before expected period in irregular cycles ≥5 ng/mL suggests ovulation; ≥10 ng/mL more reliable indicator Timing errors common if cycle irregular LH surge (urine OPK) Starting from Day 10–12 in typical cycle Surge detected 24–36 hours before ovulation False positives in PCOS (multiple LH peaks) Follicular tracking ultrasound Serial scans from Day 8–10 Dominant follicle development and collapse confirms ovulation Requires multiple visits; resource-intensive in primary care Day 2-3 FSH/LH Day 2–4 of cycle Elevated FSH indicates diminished ovarian reserve; high LH:FSH ratio suggests PCOS Single-cycle snapshot; inter-cycle variability exists Ovarian reserve assessment Ovarian reserve testing estimates the remaining primordial follicle pool and predicts ovarian response to stimulation. Two primary tests: AMH (Anti-Müllerian Hormone): Can be measured on any day of the cycle. AMH ≥1.0 ng/mL generally indicates adequate ovarian reserve; AMH <1.0 ng/mL suggests diminished reserve. AMH <0.5–0.7 ng/mL (laboratory-specific thresholds vary) indicates severely diminished reserve requiring earlier specialist referral. Antral Follicle Count (AFC): Transvaginal ultrasound on Day 2–4 counting follicles 2–10 mm in each ovary. Total AFC <5–7 suggests diminished reserve; AFC >20 raises OHSS risk in stimulation cycles. AFC is operator-dependent and may not be feasible in a general practice setting. Uterine and tubal assessment Baseline pelvic ultrasound: Assess uterine size, shape, and myometrium (fibroids, adenomyosis features), endometrial thickness and pattern in relation to cycle phase, and ovarian morphology (AFC, PCO pattern, ovarian cysts). This is the first-line uterine assessment tool available in most OBGYN practices. Tubal patency: A blocked or damaged tube is a significant fertility factor that a basic pelvic ultrasound will not reveal. Standard options: HyCoSy (Hysterosalpingo-Contrast Sonography): Ultrasound-based tubal assessment using contrast agent. Acceptable sensitivity for tubal patency; avoids radiation; requires operator experience. HSG (Hysterosalpingogram): Fluoroscopic or digital X-ray with contrast — provides uterine cavity outline and tubal patency. Standard referral-level investigation where laparoscopy is not the first step. Note: false positive rates for tubal spasm exist — confirm before proceeding to surgical treatment. Diagnostic laparoscopy: Gold standard for tubal and peritoneal assessment — direct visualisation of tubes, peritoneum, and endometriosis. Reserved for cases where pelvic pathology is clinically suspected or HSG is inconclusive. Endocrine investigations: Day 2-3 FSH, LH, E2, prolactin, TSH, and AMH as discussed. Add testosterone, DHEAS, and 17-OHP where PCOS or androgen excess is suspected. The male partner workup The male partner evaluation must happen at the first visit — not as a fallback after female investigations. The reason is not merely philosophical: male factor is present in up to 50% of infertile
