Document Summary

The seminal vesicles, which lie posterior to the urinary bladder, produce about 60% of the added fluid. Another 30% or so comes from the prostate gland whose alkaline secretions help neutralize the acidity of the urethra and vagina. Hypertrophy makes urination difficult since the gland completely surrounds the urethra. Prostate cancer represents slightly less than 1/3 of the cancers in men. The bulbourethral (cowper"s) glands lie at the base of the penis. Their secretions are also somewhat alkaline and help neutralize acidity in the urethra and vagina. Sperm plus other products of testes and accessory glands. Semen is the combination of sperm plus the products of the testes and accessory glands. Alkaline secretions neutralize the ph within the urethra and vagina. Formation of sperm spermatogenesis involves both meiotic cell division and maturation of the sperm in a process called spermiogenesis.

Overall, what is the function of the male accessory glands, andwhat are these?

		The bulbourethral glands, seminal vesicles and prostate producesemen which transports, nourishes, and protects sperm.
		The sertoli cells and the seminiferous tubules produce numerouscytokines that direct the development of sperm
		The testes produce cytokines that direct the development ofsperm and stimulates the production and release of testosterone bythe anterior pituitary
		The anterior and posterior pituitary release gonadotropins whichincrease the rate of spermatocyte maturation and stimulate theproduction of semen on a circadian cycle

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.
