Explanation:

The vertebrate reproductive systems consists mainly of gonads and associated reproductive ducts and glands. In the male reproductive system, the gonads are the testes which produces spermatozoa or sperms. The two testes are present in the lower part of the abdomen which descends into a sac outside the body, called the scrotum at puberty. Production of sperms and male sex hormone, testosterone occurs in the testes at puberty. EPIDIDYMIS is a long coiled tube, about 6m long) that lies outside each testis. It functions to store sperm produced from the testes.

One of the accessory glands associated with the sperm ducts is the PROSTATE GLAND. They add secretions known as seminal fluid to the sperm which aid it's mobility, provide nutrients and protects it by neutralising the acidity produced by any urine present in the urethra.
