Trace the pathway of sperm from their production to their exit from the body during ejaculation
What will be an ideal response?
Sperm are formed in the seminiferous tubules of the testes. Sperm are matured in the epididymis where they gain the ability to swim. During ejaculation, peristaltic waves squeeze sperm from the epididymis to the ductus deferens. The ductus deferens enters the pelvic cavity and travels to the posterior side of the urinary bladder where it empties into an ejaculatory duct. Each ejaculatory duct travels through the prostate to merge with the urethra. Ejaculation carries the sperm through the prostatic urethra, membranous urethra, and spongy (penile) urethra to exit the body.
