OBG · Infertility: semen analysis

Sample item

In an infertility evaluation, why should an abnormal semen analysis generally be repeated before drawing conclusions?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Semen parameters show substantial biologic variability

Semen quality can vary with illness, abstinence interval, and collection conditions. Repeating an abnormal result helps confirm whether a clinically meaningful male-factor abnormality is present.

Option by option

  • A. It prevents pregnancy

    Testing has no contraceptive effect.

  • B. A single test always diagnoses azoospermia permanently

    One result should not automatically be considered permanent or definitive.

  • C. Semen parameters show substantial biologic variability (correct)

    Correct. Variability means one result may not represent usual semen quality.

  • D. Repeat testing changes ovarian reserve

    Semen testing does not alter ovarian reserve.
