An LH (luteinizing hormone) blood test measures the level of a hormone made by the pituitary gland that helps control the reproductive system. It is ordered to evaluate fertility, menstrual problems, puberty timing, or pituitary function.

What it measures

  • Luteinizing hormone (LH) — The main hormone measured; it triggers ovulation in women and testosterone production in men.
  • Follicle-stimulating hormone (FSH) — Often checked alongside LH because the two work together in reproduction.
  • Estradiol — A form of estrogen sometimes measured with LH in women.
  • Testosterone — A male hormone sometimes measured with LH in men.
  • Progesterone — Sometimes checked to confirm whether ovulation has occurred.

Who it is for

A clinician such as a primary care doctor, gynecologist, urologist, or endocrinologist typically orders this test. It may also be ordered as part of a fertility evaluation.

Preparation

No fasting is usually required. Timing can matter, so follow your clinician's instructions about which day of your cycle to test, if applicable.

Results and what they mean

Results are reported as a number with a reference range that varies by age, sex, and menstrual cycle phase. A clinician interprets your result alongside symptoms and other tests. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
