As with the ovaries, we see that the testes are influenced by hormonal secretions from the anterior pituitary gland. Luteinizing hormone, LH, stimulates testosterone production and follicle-stimulating hormone, FSH, is the anterior pituitary hormone that stimulates production of sperm.he gonads are the organs that make sex hormones and reproductive cells. We do see that sex hormones are produced by the adrenal cortex; however, the secretion of sex hormones from the adrenal cortex is minimal compared to the amount produced by the gonads.
