A couple has been investigated for infertility. The husband's semen analysis shows total progressive motility 28% (normal ≥ 32%), total motile count adequate, morphology 3% (Kruger strict criteria, normal ≥ 4%). This pattern is BEST described as:
- A Oligoasthenozoospermia
- B Asthenoteratozoospermia ✓
- C Isolated teratozoospermia
- D Oligoteratozoospermia
Correct answer: B. Asthenoteratozoospermia
Explanation
WHO 2021 fifth edition reference values are: progressive motility ≥ 42% (total motility ≥ 32%), morphology ≥ 4% (Kruger strict). This man has reduced progressive motility (asthenozoospermia) and reduced morphology (teratozoospermia) with normal count — hence asthenoteratozoospermia. Oligozoospermia refers to reduced total sperm count (< 16 million/mL or < 39 million per ejaculate). Options B and D incorrectly imply low count.
