Document Summary

Introduction: reproduction is the most important characteristic of animal and plant (living) kingdom. Deferens), accessory glands (seminal vesicles, prostate, bulbourethral glands) and penis: function: elaboration of sex hormones and formation and delivery of male gametes into female reproductive tract. The testis complex organ composed of different tissues and cell types: primary function: production of spermatozoa, the male gamete, also produce androgens, particularly testosterone, by interstitial (leydig cells). The androgens don"t act on the germ cells themselves, they maintain the sertoli cells, which are required for spermatogenesis. Androgens promote: embryo development of male fetus, initiation and maintenance of spermatozoa production, development of accessory organs and 2o sex characteristics, secretion of accessory glands. Each tubule is separated by a stroma (interstitium)which contains interstitial (leydig) cells, blood and lymphatics: excretory ducts: Intratesticular: rete testis, ductus efferentes (cross the tunica albuginea @ mediastinum of testis: extratesticular: epididymis (has three portions), vas deferens. Cluster of leydig cells in loose ct b/w seminiferous tubules.

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.
