THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Sperm production in the testes takes place in coiled structures called seminiferous tubules. Along the top of each testicle is the epididymis. This is a cordlike structure where the sperm mature and are stored. The release process starts when the penis fills with blood and becomes erect.

Detailed explanation-2: -Before sperm are able to “swim, ‘’ they must mature in the epididymis. The mature sperm are then stored in the epididymis until ejaculation occurs. Ejaculation is the process in which semen is propelled by peristalsis in the vas deferens and ejaculatory ducts from the urethra in the penis.

Detailed explanation-3: -Next to each testicle, the epididymis is a tube where sperm is stored. From here, sperm are transported to the vas deferens.

Detailed explanation-4: -The rete testis connect to a structure called the epididymis. When sperm leaves the testicles it is immature and immotile, meaning it cannot yet ‘swim’ to reach an egg. Sperm remain in the epididymis for 18-24 hours before they develop the ability to swim.
