Sperm release pathway. Overview. The key male reproductive organs include the testes, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. The testes are composed of coiled structures called seminiferous tubules, which are the sites of sperm production.
Vas deferens is cut, preventing sperm from entering the urethra and thus preventing fertilization. Sperm are still produced in the testis and the volume of semen is not significantly reduced (sperm contribute very little to the volume of semen) The condition benign prostatic hypertrophy, in which the prostate is enlarged, often results in urinary retention-the inability to completely empty the bladder.
