So in males, the follicle stimulating hormone stimulates the surtole cells to provide nutrients to the developing sperm cells. Now, as time progresses, what our surtole cells can do is they can basically release a glycoprotein hormone into our surrounding area, into our bloodstream known as Inhibit. And what Inhibit does is it goes into our bloodstream and it travels to our interior pituitary gland and it basically inhibits via a negative feedback loop, it inhibits the release of our follicle stimulating hormone from the interior pituitary gland. So to review what we just discussed, let's take a look at the following flow chart. So let's begin with our hypothalamus. So the hypothalamus produces a hormone known as GnRH, the gonadotropin releasing hormone which then travels to the anterior pituitary gland through the hypothesial portal system.
