Physiology of the Male Reproductive System

Physiological changes occur to male genitalia during sexual arousal.

Sperm are the male "seeds," germ cells, or gametes.

Male gametes (sperm cells) are haploid cells produced via spermatogenesis.

Semen is a fluid produced by the seminal vesicles.

The male reproductive system is regulated by the production, stimulation, and feedback of specific hormones.
