In the male, the principal sex hormones are the androgens, of which testosterone is the most important. The androgens are steroid hormones produced mainly by the Leydig cells(interstitial cells located near the seminiferous tubules) of the Testes. Testosterone and other androgens are directly responsible for the primary and secondary sex characteristics of the male. In addition to specific sexual behaivor and sex drive the androgens also increase general agressiveness, and are respnsible for vocal behaivor such as singing in birds and calling in frogs. With the hormonal control of the male system the Gonadotropin-releasing hormone (GnRH) from the hypothalamus stimulate the anterior pituitary to secrete two gonadotropic hormones with different effects on the testes. One hormone is luteinizing hormone (LH) which acts on the Leydig cells which produce androgens mainly testosterone. The other hormone is follicle stimulating hormone (FSH) which acts on Sertoli cells that nourish developing sperm cells this in turn will produce sperm.

hormones
Function of inhibin hormones in males?
Inhibin regulates sperm production
Sperm is not antigen why?
The reason why sperm is not an antigen is because it does not stimulate antibody production. An antigen typically occurs in blood plasma.
Why do hormones affect some organs but not others?
Because hormones have specific hormone binding sites to act
Two hormones that stimulate white blood cells production are?
interlukins, and (csf) colony stimulating factor
What is secreted by the anterior pituitary to stimulate sperm cell production?
It is probably Follicle stimulating hormone.
