Document Summary
Reproductive endocrinology: differences in reproductive endocrinology in males/females is quantitative and not qualitative. Control of reproductive function: similar chain of signals function in males & females, gonadotropin releasing hormone (gnrh) Maturation of spermatozoa: two cell types critical for maturation of spermatozoa: Sertoli cells located outside seminiferous tubules located within seminiferous tubules: synthesize androgens in response to. Involved with sperm maturation process; envelop germ cells throughout development: synthesize androgen binding. Protein (abp) & inhibin in response to fsh. Gnrh, lh and fsh release: hypothalamic-pituitary-seminiferous-tubules axis: non steroidal inhibin secreted by. Sertoli cells inhibits only fsh release: contrarily to females, no (+) feedback control in males. *as follicle matures from primary to secondary, cells from ovarian stroma surrounding follicle differentiate and become steroid producing cells known as theca cells (theca interna: theca interna and granulosa cells collaborate for synthesis of higher amounts of estrogen. Luteinization: luteinization takes place after ovulation, as ruptured follicle is transformed into.
