THE REPRODUCTIVE SYSTEM: THE TESTES
Posted under Men's Health-Erectile Dysfunction by adminThe testes are a man’s reproductive organs. There are two of them, each less than two inches long and about an inch wide. Each testis lies protected in the scrotum, attached like a pocket watch on a chain to a spermatic cord, which, among other things, is responsible for supplying blood to the testis.
The testes are divided into hundreds of minuscule compartments, each of which contains at least one pair of threadlike, highly convoluted tubules. If these tubules were straightened out, each would stretch to two feet in length. These tiny tubules are joined, like plumbing pipes, to straighter tubes that are the body’s factories for sperm; the sperm-making process, called spermatogenesis, happens here. The testes are also the main source of the male hormone testosterone, which is responsible for fertility and for secondary sexual characteristics such as post-pubertal body hair and deepening of the voice.
Inside the scrotum are the testes, a man’s reproductive organs. Sperm are made here, in hundreds of threadlike, convoluted tubules. The tubules in each testis converge like a series of streams at the mouth of a river to form the head of the epididymis—a twisting, winding “greenhouse” where sperm mature and are stored until orgasm. During orgasm, two-thirds of ejaculated sperm are rocketed from the tail of the epididymis during a series of powerful muscle contractions.
The epididymis melts into still another tube, called the vas deferens—a hard, muscular cord, designed to pump sperm to the prostatic segment of the urethra. The vas deferens eventually meets with the duct of the seminal vesicle to form the ejaculatory duct.
