📘Easy summary
Testes (in scrotum, cooler temperature): seminiferous tubules make sperms; interstitial (Leydig) cells make testosterone. Epididymis: stores and matures sperms. Vas deferens: carries sperms to urethra. Accessory glands — seminal vesicles, prostate, Cowper's — add fluids forming semen (nutrition, mobility). Urethra and penis deliver semen. Sperm: head with nucleus and acrosome (enzymes to penetrate egg), middle piece with mitochondria (energy), tail (swimming).
