Document Summary

Testes = where sperm is produces (have coiled tubes seminiferous tubules) Vas deferens = delivers sperm to urethra, scrotum & penis. Immature sperm spends 20days in epididymis where they mature. Epididymis & vas deferens main site for sperm storage. Contribute to production of semen: prostate gland: produces fluid to activate sperm, seminal vesicle: activates & nourishes sperm, bulbourethral gland: produces mucus to cleanse urethra (also seen in foreplay) Epididymis > vas deferens > ejaculatory duct > pass thru prostate gland > urethra. Sperm is ejaculate that contains sperm & nutritive fluid. Seminal fluid has sugar that gives sperm cells energy & has antibacterial substances that aid sperm mobility. During development testes leave body & turn into scrotum for protection. Testes have lower temp aiding in sperm maturation. Urethra made of erectile tissue that fills w blood when aroused. Blood flow cause by vasodilation of penis vessels.

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.
