Special instructions

Luteinising Hormone (LH) is produced by the pituitary gland and is important for male and female fertility. In women it governs the menstrual cycle, peaking before ovulation. In men it stimulates the production of testosterone.

During the menstrual cycle high levels of LH at mid-cycle triggers the release of the egg from the ovary. LH also stimulates the ovaries to produce other hormones such as oestradiol and progesterone. During the menopause, LH concentrations rise.

LH is often tested along with other tests such as FSH, oestradiol and progesterone in the investigation of infertility in both men and women. LH levels are also useful in the investigation of irregular periods and to help evaluate the function of the pituitary gland, which regulates the hormones that control the reproductive system.
