Pathway of sperm, animation

Référence de la vidéo 11936046
Pathway of sperm. Animation showing the path of sperm, the male gamete (sex cell), from the testes to ejaculation. Sperm are produced within the testes (purple) in seminiferous tubules (flashing red). From here they move to the epididymis (yellow coils around testis) where they mature. When the penis becomes erect (not seen), mature sperm move from the epididymis to the vas deferens (yellow tubes). Secretions are added to the sperm from the seminal vesicles (green) to form seminal fluid. This then passes through the prostate gland (pink) where fluid is added to form semen. The semen travels down the urethra, leaving the penis at ejaculation.
