Also known as: FSH and LH, LH and FSH, Luteinizing Hormone (LH) and Follicle-stimulating Hormone (FSH).

The amounts of FSH and other hormones (luteinizing hormone, progesterone, and estrogen) are measured in both a man and a woman to determine infertility. The FSH level may help determine whether male or female sex organs (testicles or ovaries) are properly functioning.
