![]() FSH and LH then stimulate the testis to produce testosterone. When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. Hormone (FSH) and gonadotropin-releasing hormone (GnRH). Adrenalin hormone is released mainly through the activation of nerves connected to the adrenal glands, which trigger the secretion of adrenalin hormone and thus increase the levels of adrenaline in the blood. Hormones involved are luteinizing hormone (LH), follicle-stimulating Pituitary, and testicular endocrine glands.
