Like women, the male reproductive organs are both internal and external to the pelvic area. They produce and release semen during sexual intercourse to fertilise the ovum. Sperm is produced in the testes, kept in the seminal vesicles and then at ejaculation carried in semen through the vas deferens and the erect penis.

Male external organs include the penis and scrotum. Internal sexual organs include the testes, epididymis, vas deferens, seminal vesicles, prostate gland, cowper's/bulbo urethral glands and urethra.

The scrotum protects the epididymis, vas deferens and testicles.
It also regulates the temperature of the testicles keeping them at a lower body temperature necessary for the production of sperm. The accessory glands of the prostate, urethra and seminal vesicles produce fluid to nourish and support sperm and lubricate the system.
