Which of the following is a common disorder of the male reproductive system?

• A. Oligospermia
• B. Hemophilia
• C. Hypertension
• D. Migraine

Answer: (A)

Low sperm count, or oligospermia, is a common disorder affecting male fertility, making it the best fit for a question about male reproductive system problems. It means there are fewer sperm in semen, typically below about 15 million sperm per milliliter, which reduces the chances of fertilization. Many factors can contribute, including hormonal imbalances, testicular issues, varicocele, infections, heat exposure, smoking, heavy alcohol use, and certain medications; addressing the underlying cause is the primary approach, with lifestyle changes or assisted reproductive techniques as needed. The other options do not pertain to the male reproductive system: a bleeding disorder, a cardiovascular condition, and a neurological condition are not specific to male fertility.
