what is the sperm testes barrier
cellular barrier around the seminiferous tubule that prevents immune system from reaching the testes as to not kill the sperm
what is the germ cell in spermatogenesis
spermatogonium
what is the function os sertoli cells
facilitate spermogenisis (development of spermatogonium to spermatozoa)
name the different cells in the stages of spermogenisis ascending up the seminiferous tubule.

primary spermatocyte
secondary spermatocyte
spermatids
spermatozoa
what occurs during cytoplasmic remodelling
sperm develops for spermination (release)
ie: chromatin condenses
flagellum + headpiece forms
acrosome forms
cytoplasm sheds
what stimulates testosterone production
luteinising hormone to leydig cells
what triggers spermatogenisis
testosterone +
Follicle stimulating hormone to sertoli cells
what inhibits the production of FSH
inhibin - released due to the secretion of FSH for negative feedback
