Causes of Infertility — Prelims Strategy

Prelims Strategy

To effectively tackle NEET questions on 'Causes of Infertility', a multi-pronged strategy is essential. Firstly, master the definitions of key terms like primary/secondary infertility, azoospermia, oligospermia, anovulation, etc.

Secondly, categorize causes clearly into male, female, combined, and unexplained factors. For each category, list the specific conditions and their primary mechanisms. For example, for male factors, remember varicocele (heat effect), genetic defects (Klinefelter), and ejaculatory issues.

For female factors, focus on ovulatory disorders (PCOS, POI), tubal factors (PID, endometriosis), and uterine factors (fibroids, Asherman's).

When encountering numerical problems (less common here but possible for hormonal levels), ensure you know normal ranges. For conceptual questions, pay close attention to keywords in the question stem, such as 'irregular periods,' 'hirsutism,' 'scrotal swelling,' or 'blocked tubes,' as these are direct clues to specific conditions.

Practice identifying the most likely cause from a given set of symptoms. For trap options, understand why they are incorrect – often they describe a different condition or a secondary effect rather than the primary cause.

Regularly revise the hormonal axes (hypothalamic-pituitary-gonadal) for both sexes, as disruptions are a frequent source of questions. Finally, practice MCQs that require differentiating between similar-sounding conditions to solidify your understanding.
