00:00Sperm are produced and released by the male reproductive organs.
00:08The testes are where sperm are produced.
00:13The testes are linked to the rest of the male reproductive organs by the vas deferens,
00:18which extends over the base of the pelvic bone, or ileum,
00:23and wraps around to the ampulla, seminal vesicle, and prostate.
00:28The urethra then runs from the bladder through the penis.
00:35Sperm production in the testes takes place in coiled structures called seminiferous tubules.
00:43Along the top of each testicle is the epidemius.
00:48This is a cord-like structure where the sperm mature and are stored.
00:53The release process starts when the penis fills with blood and becomes a wreck.
01:00Continuing to stimulate the penis will cause an ejaculation.
01:04Mature sperm begin their journey by traveling from the epidemis to the vas deferens,
01:10which propels sperm forward with smooth muscle contractions.
01:14The sperm arrive first at the ampulla, just above the prostate gland.
01:21Here, secretions from the seminal vesicle, located next to the ampulla, are added.
01:27Next, the seminal fluid is propelled forward through the ejaculatory ducts toward the urethra.
01:34As it passes the prostate gland, a milky fluid is added to make semen.
01:41Finally, the semen is ejaculated from the penis through the urethra.
