The LH test measures the level of luteinising hormone, a hormone produced by the pituitary gland. LH plays a crucial role in the reproductive system by triggering ovulation in females and stimulating testosterone production in males.

Elevated LH levels can be associated with polycystic ovary syndrome (PCOS), ovarian failure, or menopause.

Low LH levels may indicate hypothalamic dysfunction or conditions like anorexia nervosa or excessive exercise.
