MICROANATOMY

Detailed explanation-1: -Ejaculation occurs when peristalsis of the muscle layers of the vas deferens and other accessory structures propel sperm from the epididymes, where mature sperm are stored. The muscle contractions force the sperm through the vas deferens and the ejaculatory ducts, and then out of the penis through the urethra.

Detailed explanation-2: -Ductus deferens (vas deferens) is a thick walled, fibromuscular tube that is continuous with the epididymis. Peristaltic movements propel sperm through the duct.

Detailed explanation-3: -The ductus deferens only functions during ejaculation. Ejaculation is an autonomic reflex that propels sperm from the epididymis to the outside of the body. During ejaculation, sperm are propelled by peristalsis of smooth muscle in the ductus deferens from the tail of the epididymis to the ejaculatory duct.
