Explanation:
Detailed explanation-1: -LH is transported in the blood stream to the testes, where it stimulates Leydig cells to produce testosterone: this can act as an androgen (via interaction with androgen receptors) but can also be aromatized to produce estrogens.
Detailed explanation-2: -Luteinizing hormone (LH) stimulates testosterone production. If too much testosterone is produced, the hypothalamus alerts the pituitary gland to make less LH, which tells the testes to decrease testosterone levels.
Detailed explanation-3: -Testosterone and FSH(Follicle Stimulating Hormone) from the pituitary gland then act together on the seminiferous tubules (sperm-producing tubes) in the testes to make sperm.
