What level of LH indicates menopause?
During and after menopause, a woman's luteinizing hormone levels rise significantly due to the cessation of ovarian function and the subsequent loss of negative feedback on the pituitary gland. While normal pre-menopausal levels fluctuate across the menstrual cycle between approximately 5 and 25 International Units per liter, post-menopausal luteinizing hormone blood concentrations typically surge and remain elevated within a higher reference range of roughly 14 to over 58 International Units per liter, serving as a reliable biochemical indicator of ovarian senescence.
