Write about different parts of the male reproductive system of human beings.

The male reproductive system of human beings consists of a pair of testes, sperm ducts, urethra, penis and accessory glands. Each of them is briefly described below:

1. Testes — Testes are located outside the abdomen in a sac-like structure called scrotum. They are the primary reproductive organs of the male reproductive system. They produce the male gametes called sperms.
2. Sperm Ducts — The sperms produced in the testes, travel through the sperm duct or vas deferens to reach the urethra.
3. Accessory Glands — As the sperms pass through the sperm duct, secretions from the accessory glands are mixed with them. This mixture is called semen.
4. Urethra — It is a tube through which urine and semen passes.
5. Penis — Through penis, sperms are discharged and deposited into the vagina of the female body. In males, the penis is the organ used both for the discharge of the urine and the sperms.
