How is it used
Follicle-stimulating hormone (FSH) is a hormone which is associated with reproduction, ovulation in women and sperm production in men. FSH levels are tested along with luteinizing hormone (LH), testosterone, estradiol or progesterone. FSH levels help to evaluate infertility, improper functioning of the ovaries or testicles, diagnose pituitary or hypothalamus disorders. FSH levels are also helpful to evaluate menstrual irregularities, confirm menopause. In men, FSH levels are used to evaluate low sperm count and In children to investigate delayed or early puberty.
