MICROANATOMY

Detailed explanation-1: -Mature sperm begin their journey by travelling from the epididymis to the vas deferens, which propels sperm forward with smooth muscle contractions. The sperm arrive first at the ampulla just above the prostate gland. Here, secretions from the seminal vesicle located next to the ampulla are added.

Detailed explanation-2: -When ejaculation occurs, sperm are forcefully expelled from the tail of the epididymis into the vas deferens. Sperm then travel through the vas deferens through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder.

Detailed explanation-3: -Sperm are stored in the proximal portion of the ductus deferens, near the epididymis, and peristaltic movements propel the sperm through the tube.

Detailed explanation-4: -Sperm Maturation The spermatids grow a tail and lose excess cytoplasm from the head. When a sperm is mature, the tail can rotate like a pr opell er, so the sperm can propel itself forward. Mitochondria in the connecting piece produce the energy (ATP) needed for movement.
