FSH testing in perimenopause: what it means
FSH rises as ovarian reserve falls, but perimenopausal levels swing week to week. Two elevated values >30 IU/L, 4\u20136 weeks apart, in a symptomatic woman over 45 confirm the transition \u2014 but they aren't required.
Key points
- Two elevated FSH values 4–6 weeks apart
- Interpret alongside symptoms, cycle history
- Skip in women on hormonal contraception
