Potentiates the activity of testosterone on spermatogenic cells
Androgen-binding protein
The testes
Are enclosed in protected by the scrotum
in females, exerts feedback inhibition on the hypothalamus and anterior pituitary
B)Estrogen E)Inhibin G)Progesterone
Hormones that directly regulate the ovarian cycle
C)FSH F)LH

Spermatogenesis
Is the sequence of events that lead to the formation of sperm
