(2) Seminiferous tubules: Located in the testes, help produce sperm; size of a football field if stretched out; very tightly coiled (2) Epididymis: Coiled tube, connects each testicle to its vas deferens, helps store sperm, until they are ready for transport; surrounds testicles. Takes 70 days to mature to sperm cell, stored in epididymus. (2) Vas deferens: Transport sperm from the epididymis in anticipation of ejaculation, tube connecting from epididymis to ejaculatory duct (2) Seminal vesicles: Little tiny things near the prostate and ejaculatory duct, propel the sperm forward by flexing a muscle. 70% of semen mixture (1) Prostate gland: Function of the prostate is to secrete a slightly alkaline fluid, milky or white in appearance, usually consists 30% of the volume of semen to help neutralize the acidity of the vagina. (2) Cowper’s Glands: located on each side of the urethra right below the prostate gland. Alkaline; helps to lubricate the flow of semen and buffer acidity of the urethra; clear droplet that can form when aroused. Can occasionally contain live sperm cells. Semen: Alkaline mixture from cowpers, prostate and seminal vesicle to help sperm swim through acidic vagina Testosterone: Hormone which governs male sex drive and physique; what changes female to male in development; can measure levels through blood (2) Corpora cavernosa: cavernous bodies: Two large round pieces of tissue which inflate with blood to make the penis erect; also with clitoris
