Anatomy of the male reproductive system

male reproductive system

Epididymis is a tube-like structure which connects the testis and the vas deferens. The sperms are stored and matured in the epididymis.

Prostate is a gland that lies just below the urinary bladder and surrounds the upper part of the urethra. It produces a milky white fluid that forms a part of the semen.

Scrotum is the pouch of skin which hangs below the penis and holds the two testes.

Semen is the fluid ejaculated out during sexual arousal. It contains sperms produced by the testes, seminal fluid which is produced by the seminal vesicles and which contains sugars to provide the sperms with energy and a milky white fluid from the prostate gland.

Seminal vesicles
Seminal vesicles are glands that lie below the prostate. They produce seminal fluid which is rich in fructose. This fructose provides nutrition to the sperms.

Sperms are the male reproductive cells. They are produced in the testes. They are carried in fluid called semen. Sperms are capable of fertilising an egg cell to form a zygote.

Testes (singular - testis) are the male gonads. They are situated in the scrotum. The cells of the testis produce sperms and the male hormone, testosterone.

Urethra is the tube in the penis that passes urine and semen out of the body.

Vas deferens
The two vas deferens (plural - vasa deferentia) are thin tubes which carry sperms from the testes to the urethra. Vas deferens is also known as sperm duct. Each vas deferens is about 45 cms long.
