Concept: The epididymis is the part of the male reproductive system where sperm mature and are temporarily stored.
Explanation: The testes produce sperm and the male hormone testosterone.
The scrotum holds and protects the testes.
The epididymis is a coiled tube attached to each testis that stores sperm temporarily until ejaculation.
The sperm duct, or vas deferens, carries sperm from the epididymis to the penis during ejaculation.
The prostate gland secretes seminal fluid that nourishes and activates sperms.
This fluid mixes with sperms to form semen.
So, the part that stores sperms temporarily is the epididymis.
