Sperm Release Pathway
Description
Male reproductive components are the testes, urethra, vas deferens, prostate, seminal vesicles, and penis. The testes are made up of seminiferous tubules, coiled structures where sperm production occurs. Sperm migrate to the epididymis, on top of the seminiferous tubules, where they mature and are stored. When the penis fills with blood and becomes erect, with sufficient stimulation an ejaculatory process begins. The mature sperm travel from the epididymis through the vas deferens, a muscular tube that propels sperm forward with smooth muscle contractions. The sperm arrive at the ampulla where secretions from the seminal vesicles are added. From the ampulla, seminal fluid is propelled forward through the ejaculatory ducts toward the urethra, first passing the prostate where a milky fluid is added to form semen. Finally, the semen is ejected, or ejaculated, through the far end of the urethra.
