Question

Infertility in human males is sometimes due to the failure of the spermatids to develop into mature sperm. This failure to mature is due to

• A. Blocked seminiferous tubules
• B. Lowered testosterone levels
• C. Inflammation of the epididymis
• D. All of these

Answer 1

The correct option is D All of these

The seminiferous tubules function to produce sperm , maintain sperm and store them . Testosterone stimulates the sperm production . The epididymis is a tube at the back of the testicle that stores & carries sperm . Therefore , any kind of damage to any of these 3 can affect the sperm product , hence the fertility of man .

So the correct option is 'All of these' .
