Where is ejaculate produced

During sexual intercourse, semen moves through a series of ducts to deliver the semen directly into the female reproductive system. The testes or testicles are the male gonads and sit below the penis within a sac called the scrotum. They are cm long, 2. The testes generate sperm, the male sex cells, as well as testosterone and other sex hormones. The production of sperm is constant and occurs within numerous lobules in each testis. First, structures called seminiferous tubules generate stem cells.

These cells, the spermatogonia, divide into spermatocytes, and then divide further to become spermatids. The process is called spermatogenesis. Spermatids move from the testis to the epididymis and mature into sperm. The epididymis, vas deferens, ejaculatory ducts, and urethra form a four-part transportation system. The epididymis sits directly on top of each testis.

Sperm from the testis mature as they move through the coiled duct of the epididymis. During sexual intercourse and ejaculation, they are expelled into the vas deferens. The vas deferens pushes the sperm up over the bladder and down toward the prostate gland. There, the vas deferens joins the ends of the seminal vesicles accessory reproductive glands to form the ejaculatory ducts. The ejaculatory ducts receive seminal fluid from the vesicles, pass through the prostate, and move semen into the urethra.

Continuing to stimulate the penis will cause an ejaculation. 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. Next, the seminal fluid is propelled forward through the ejaculatory ducts toward the urethra. As it passes the prostate gland, a milky fluid is added to make semen.

Seminal Vesicles The seminal vesicles are a pair of coiled glands located below the bladder and next to the vas deferens. Prostate Gland The prostate gland is located beneath the bladder and in front of the rectum.
