DESCRIPTIONLuteinizing hormone (LH) is a hormone released in both men and women by the anterior pituitary gland in the brain. Production of LH is controlled by the reproductive system, the pituitary gland, and the hypothalamus. Levels of LH in women fluctuate over time. In women, LH levels naturally increase in the middle of the menstrual cycle, causing ovulation. They also increase during menopause. In men, LH stimulates production of the hormone testosterone. Levels of LH remain fairly constant in men.
LH levels are useful in the investigation of menstrual irregularities and to aid in the diagnosis of pituitary disorders or diseases involving the ovaries or testes. LH may also be ordered when a boy or girl does not appear to be entering puberty at an appropriate age (either too late or too soon). Irregular timing of puberty may be an indication of a more serious problem involving the hypothalamus, the pituitary gland, the gonads (ovaries or testes), or other systems. The measurement of LH may differentiate between benign symptoms and true disease.
An abnormally high level of LH in the blood may indicate:
An abnormally low level of LH in the blood may indicate hypopituitarism or Kallmann syndrome.
POLICYMeasurement of luteinizing hormone is considered medically necessary to distinguish between pituitary, hypothalamus, and gonad disorders in males with hypogonadism or hypergonadism.
Measurement of luteinizing hormone is considered medically necessary to distinguish between pituitary, hypothalamus, and gonad disorders in females with symptoms of ovarian dysfunction.
Measurement of luteinizing hormone is considered not medically necessary when performed for screening purposes in asymptomatic patients (absence of signs, symptoms, or disease).
