Which test assesses male factor fertility in infertility evaluation?

• A. Semen analysis.
• B. LH surge test.
• C. Hysterosalpingography.
• D. TSH level.

Answer: (A)

The key idea is that male factor fertility is assessed most directly by examining semen quality. A semen analysis looks at the semen you ejaculate and provides concrete details about the sperm: how many there are (count), how well they move (motility), and what proportion have a normal shape (morphology), along with volume and other basic parameters. These sperm-focused measurements reveal common problems like low sperm concentration, poor movement, or abnormal forms, which are frequent causes of infertility in couples.

This test is the best choice because it directly evaluates the male side of fertilization potential. The other options don’t assess male fertility: the LH surge test tracks ovulation in the female partner, hysterosalpingography checks whether the fallopian tubes and uterine cavity are open, and a thyroid-stimulating hormone level looks at thyroid function that can influence overall fertility but doesn’t tell you about the male’s semen quality. Semen analysis remains the standard first step in evaluating male fertility since it provides actionable information about the likelihood of achieving fertilization.
