A 23-year-old woman accompanied by her mother-in-law comes to the infertility clinic. She has been having regular intercourse for 6 months but is not able to conceive. What is the next best step?

Explanation

## Correct Answer: A. Reassure and review the couple after 6 months Infertility is defined as failure to conceive after 12 months of regular unprotected intercourse in women <35 years, or after 6 months in women ≥35 years. This 23-year-old has had only 6 months of regular intercourse—she does not yet meet the diagnostic threshold for infertility. The gold standard first step is reassurance and expectant management with review after 6 months (total 12 months). This approach is cost-effective, avoids unnecessary investigations, and respects the natural fertility window; approximately 80–90% of couples conceive within 12 months. Immediate invasive investigations (laparoscopy, hysteroscopy) or partner evaluation are premature and not aligned with WHO/ICMR guidelines for infertility workup. The presence of the mother-in-law may reflect social pressure in the Indian context, but clinical management must follow evidence-based timelines, not family expectations. Reassurance addresses anxiety and improves compliance with follow-up. ## Why the other options are wrong **B. Hysterolaparoscopy** — Hysterolaparoscopy is an invasive diagnostic procedure reserved for confirmed infertility (after 12 months of unprotected intercourse) or when specific pathology is suspected (endometriosis, adhesions, tubal disease). At 6 months, this is premature, exposes the patient to surgical risks, and is not cost-effective. NBE may trap students who confuse 'infertility workup' with 'immediate investigation' rather than understanding the diagnostic timeline. **C. Semen analysis for husband** — Semen analysis is indicated only after the couple has been trying for 12 months (or 6 months if woman is ≥35 years). At 6 months in a 23-year-old, male factor evaluation is premature. This option may trap students who assume 'infertility clinic visit' means 'start full workup,' but the diagnostic criteria have not yet been met. **D. Diagnostic hysteroscopy** — Diagnostic hysteroscopy is used to evaluate intrauterine pathology (polyps, fibroids, septate uterus, adhesions) in women with confirmed infertility or recurrent pregnancy loss. It is not a first-line screening tool and is contraindicated before the 12-month diagnostic threshold is reached. This option represents over-investigation and is not justified at 6 months of trying. ## High-Yield Facts - **Infertility definition**: failure to conceive after 12 months of regular unprotected intercourse in women <35 years; 6 months in women ≥35 years. - **First step in infertility workup**: reassurance, counselling, and expectant management with review after 6 months (to reach 12-month threshold). - **Fecundability rate**: ~80–90% of couples conceive within 12 months of regular intercourse; 50% within 3 months. - **Invasive investigations (laparoscopy, hysteroscopy)** are reserved for confirmed infertility or suspected specific pathology, not for initial presentation. - **Semen analysis** is the first male factor investigation but is ordered only after the diagnostic threshold is met. - **Social pressure** (mother-in-law presence) does not alter the evidence-based diagnostic timeline in Indian clinical practice. ## Mnemonics **12-6 Rule for Infertility Diagnosis** 12 months for women <35 years; 6 months for women ≥35 years. Only after meeting this threshold do you proceed to investigations. **FIRST STEP = Reassurance, not Investigation** When a couple presents before the diagnostic threshold, the reflex is reassurance + expectant management + review, not laparoscopy or semen analysis. ## NBE Trap NBE pairs 'infertility clinic visit' with 'immediate investigation' to trap students who confuse clinical presentation with diagnostic criteria. The key discriminator is the 6-month timeline—this patient has not yet met the 12-month threshold for diagnosis, so reassurance and review is the only justified step. ## Clinical Pearl In Indian practice, family pressure (especially from in-laws) often drives premature investigations and unnecessary procedures. A skilled clinician reassures the couple, explains the natural fertility window, and avoids over-medicalization—this builds trust and reduces anxiety-driven demand for invasive tests. _Reference: DC Dutta's Textbook of Obstetrics (7th ed.), Ch. 13 (Infertility); ICMR Guidelines on Infertility Management_
