Document Summary

Spermiogenesis: differentiation of spermatid to sperm (spermatozoon) No cell division in this process, this process is transformational, not proliferative. Testicles are outside main pelvic cavity (must be regulated, no constant temperature) Muscular regulation: change distance of testicles from body (closer vs. further) Cremaster muscle elevates (contracts = elevates, detracts = go down) Vascular regulation: network, pampiniform venous plexus (cools arterial blood) Blood vessels, veins returning to the body (colder temperature) spread out and wrap themselves around arteries entering the network, which cools the blood by absorbing heat out of arterial blood (warms up veins, cools down arteries) to optimal temperatures. It begins with a stem cell (spermatogonium). It"s not alone in its efforts, depends on other help, which regulates processes. Sertoli cells: direct regulators of the process. Secrete growth factors that stimulate proliferation and differentiation (in response to testosterone and fsh) Release androgen-binding protein (abp) in response to fsh.
