InterpretationPRIMARY OVARIAN FAILURE: FSH >30 IU/L with LH often equally raised. Increased LH alone is not indicative. Other considerations with raised levels of LH include the mid cycle surge and PCO. LOW/UNDETECTABLE GONADOTROPHINS: May be normal but secondary hypogonadism due to hypothalamic/pituitary disorders must be considered. Also consider the possibility of raised oestrogens e.g oral contraceptives, oestrogen producing tumours.
