Human Male Reproductive System:

Its structure: Testes, Epididymis, Vas deferens, Urethra.

Testis: are located outside of the body cavity in a pouch

called the scrotum, and produce sperms.

Epididymis: a structure located on top of each testis where

sperm mature and are stored.

Urethra: the tube that carries both semen and urine outside

of the body through the penis.

Seminal vesicles: contribute over half of the semen and

secrete sugar into the fluid, which provides energy, other

nutrients, proteins and enzymes for the sperm.

• Male hormone (testosterone): made in the testes, a

steroid hormone that is necessary for the production of

sperm. It also influences the development of male

secondary sex characteristics
