OBG · Infertility

Sample item

A couple has been trying to conceive for 18 months. The woman has regular cycles. What is the first investigation to arrange for the male partner?

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

The answer and the reasoning

A. Semen analysis

Semen analysis is simple, inexpensive, non-invasive and assesses count, motility and morphology, and a male factor contributes in a large share of infertile couples. More invasive tests are used only if it is abnormal.

Option by option

  • A. Semen analysis (correct)

    Correct. It is the standard first test of male fertility.

  • B. Testicular biopsy

    Biopsy is invasive and reserved for azoospermia work-up after initial tests.

  • C. Karyotyping

    Karyotyping is used for severe oligospermia or azoospermia, not as an initial screen.

  • D. Scrotal ultrasound only

    Ultrasound can find varicocele but does not measure sperm function or number.
