Name the different parts of male reproductive system in man.

The male reproductive system in humans comprises several interconnected structures working together to produce, store, and deliver sperms. The primary organs include a pair of testes (singular: testis) housed in an external sac called the scrotum, which maintains optimal temperature for sperm production. Each testis connects to a coiled tube called the epididymis where sperms mature and are temporarily stored. From the epididymis, sperms travel through a muscular tube called the vas deferens (sperm duct) during ejaculation.

Supporting these main structures are several accessory glands that contribute secretions to create semen. The seminal vesicles produce a nutrient-rich fluid containing fructose to energize sperms, while the prostate gland secretes an alkaline fluid that protects sperms in the acidic environment of the female reproductive tract. Additionally, Cowper's glands (bulbourethral glands) release a lubricating fluid. All these components—sperm cells and glandular secretions—combine in the urethra, a common passage running through the penis that serves as the final conduit for semen expulsion during reproduction. This integrated system ensures not only sperm production but also creates the optimal chemical environment for sperm survival and successful fertilization.
