GENERAL HISTOLOGY

Detailed explanation-1: -Sperm are stored in the proximal portion of the ductus deferens, near the epididymis, and peristaltic movements propel the sperm through the tube. The proximal portion of the ductus deferens is a component of the spermatic cord, which contains vascular and neural structures that supply the testes.

Detailed explanation-2: -Smooth muscle tissue in the walls of the ductus deferens contracts in waves of peristalsis to slowly move sperm along its length.

Detailed explanation-3: -When the erect penis is stimulated, muscles around the reproductive organs contract and force the semen through the duct system and urethra. Semen is pushed out of the male’s body through his urethra-this process is called ejaculation. Each time a guy ejaculates, it can contain up to 500 million sperm.

Detailed explanation-4: -When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder.

Detailed explanation-5: -Hence the correct sequence of transport of sperms is: Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus.
