The male reproductive system is composed of several specialized organs and structures that work together to produce, mature, and transport spermatozoa, as well as produce semen.1

The primary organs and structures include:

Testes: The male gonads responsible for producing sperm and androgens. They are housed in the scrotum, which regulates their temperature.12
Sperm Canal: A series of ducts that transport sperm, consisting of the epididymis, the ductus deferens, and the ejaculatory ducts.5
Accessory Glands: These provide secretions that form the bulk of seminal fluid:
- Seminal vesicles: Produce a thick, alkaline secretion.3
- Prostate gland: Adds fluid to the semen and surrounds the urethra.3
- Bulbourethral glands: Also known as Cowper glands, these secrete a lubricating fluid.3
Penis: The external organ that contains the urethra, serving as the exit point for semen and urine.12
