The male reproductive system refers to the anatomical structures and physiological processes in the male body that are responsible for the production, maturation, storage, and release of sperm, as well as the secretion of male sex hormones. It includes both external and internal components.
Externally, the male reproductive system consists of the penis and scrotum. The penis is a muscular organ that serves as the conduit for urine and semen, while the scrotum is a pouch-like structure that houses the testicles, which are the primary male sex organs.
Internally, the male reproductive system comprises the seminal vesicles, prostate gland, Cowper's glands, vas deferens, epididymis, and testes. The testes are responsible for the production of sperm cells through a process called spermatogenesis, as well as the secretion of testosterone, the primary male sex hormone. The epididymis acts as a site for sperm maturation and storage, while the vas deferens carries mature sperm from the epididymis to the urethra.
During sexual arousal, the male reproductive system undergoes various physiological changes. The erectile tissues in the penis fill with blood, leading to an erection, while the glands secrete seminal fluid to nourish and transport sperm during ejaculation. Sperm is released from the urethra to facilitate fertilization of an egg during sexual intercourse.
