Document Summary

Testes and the associated epididymis are contained within the scrotum. The epididymis is a component of the male reproductive duct system (epididymis, ductus deferens, ejaculatory duct, urethra) Consists of blind-ended coiled tubules (seminiferous tubules) producing sperm. Between the seminiferous tubules are interstitial cells, which synthesize testosterone, needed for sperm production and maturation. Made up of a series of coiled tubes through which the sperm pass prior to ejaculation immature sperm leaving the testis spend about 20 days in the epididymis, during which they mature and acquire motility. The epididymis and vas deferens are the main sites of sperm storage. Sperm leaving the vas deferens enter the ejaculatory duct, which passes through the prostate gland. The ejaculatory duct (ed) leads into the urethra, which passes through the penis. The urethra in men begins at the urinary bladder; the ed fuses with the urethra in the prostate gland. 2 glands contribute to the formation of semen/ejaculate:

CHOOSE ALL THAT APPLY!!! Review your Lecture note packet on the Male Reproductive Anatomy. Read the following statements - and select all statements that are FALSE (hint: there are 4 FALSE answers in this question!)

		Testes - The 2 major functions of the testes are the produce spermatozoa and produce androgen hormones (testosterone)
		Testes - The nurse cells or sustentacular cells produce testosterone
		Epididymis - The epididymis has 3 regions - a head, body and a tail.
		Ductus (vas) Deferens - The extended portion of the ductus (vas) deferens as it nears the prostate gland is called the spermatic cord.
		Ejaculatory Duct - the ejaculatory duct passes through the prostate gland.
		Male Reproductive Glands - The prostate gland produces the majority of the volume of semen fluid.
		Male Reproductive Glands - The seminal vesicle produces fluids that help nourish the sperm, stimulates smooth muscle contraction and forms a temporary clost in the female's vagina.
		Male Reproductive Glands - The bulbourethral glands secrete a thick, alkaline mucus that helps neutralize any urinary acids that may harm the spermatozoa.
		Spermatozoa - The middle piece of the spermatozoa contains mitochondria and geneteic material in it.
		Spermatozoa - The head of the spermatozoa contains an acrosomal cap that contains enzymes that help during fertilization.

Identify the organ that corresponds with each of the following functions-1) Organ that allows the male to pass urine and semen leave the from his body; organ that enters the female's body during sexual intercourse.-2) Passage way through which urine and semen leave the penis.-3) Glands that produce sperm and the male sex hormone (testosterone)-4) Muscular sac where urine is stored.-5) Pouch of skin that holds the testes and controls temperature for sperm production.-6) The head or end of the penis: filled with highly sensitive nerve endings; particularly sensitive to stimulation.-7) Passageway for the sperm- 8) Coiled tube system in which sperm mature. A) Scrotum B) Urethra C) Bladder C) Vas deferens D) penis E) Testis F) Epididymis G) Seminal vesicle H) Prostate gland I) Cowper's gland J) Glans penis
