Which factor is listed as a potential contributor to limited sperm count?

• A. Chronic infections
• B. Regular exercise
• C. Balanced diet
• D. Adequate hydration

Answer: (A)

Chronic infections can contribute to a limited sperm count because they drive ongoing inflammation of the male reproductive tract, which can damage the tissues involved in sperm production and transport. Infections can cause scarring or obstruction of the ducts, and fever associated with illness temporarily suppresses spermatogenesis, reducing the number of sperm produced. Immune responses and inflammatory mediators during chronic infection can also disrupt normal sperm development and maturation, leading to oligospermia over time.

Regular exercise, a balanced diet, and adequate hydration tend to support reproductive health by improving overall physiology, testosterone balance, circulation, and semen quality. While extreme conditions of exercise or severe dehydration can transiently affect semen parameters, these factors are not typically listed as contributors to a chronically limited sperm count.
