LH levels are normally low during childhood and in women, high after menopause. Since LH is secreted as pulses, it is necessary to follow its concentration over a sufficient period of time to get proper information about its blood level. During reproductive years, typical levels are between 1 and 20 IU/L. Physiologic high LH levels are seen ...
