Sperm mature in the ____.

A) vas deferens
B) epididymis
C) prostate
D) testis
E) urethra

Sperm cells maturation occurs in the epididymis, which is a coiled tube attached to the back of each testis. The vas deferens is responsible for transporting sperm from the epididymis to the urethra during ejaculation. The prostate gland secretes a fluid that helps to nourish and protect the sperm as they travel through the reproductive tract. The urethra serves as a common pathway for both urine and ejaculate. The testis is responsible for the production of sperm.
