reproductive system - male

Each testis (plural, testes) are shown here with the overlying skin removed (red circles).

The testes contain tightly coiled seminiferous tubules, where sperm production takes place.

As with the ovaries, the testes serve a second function - to produce sex hormones like testosterone.

To get to the urethra, sperm travels from the testes and epididymides (sing., epididymis) to the ductus deferentia (sing., deferens). Glands (e.g., prostate, seminal vesicles) add fluid to the sperm as it travels from the testes to the urethra.
