Now, the other important types of cell that we have to know is our Ladic cell. This is also known as the intrastitial cell and these Ladic cells are shown in green. So we have the lady cells, we have these hertoli cells and we also have these red structures which are the capillaries that bring not only nutrients and oxygen but also important types of hormones to our testes, to our Simoniferous tubules of the testes. So in our discussion on the hypothalamus and the anterior pituitary gland, we said that the hypothalamus produces and releases a hormone known as GnRH, which stands for gonadotropin releasing hormone. And this hormone stimulates the interior pituitary gland to release two important types of hormones. We have the follicle stimulating hormone FSH and lee nizing hormone also known as LH.
