Clinical Significance
Androsterone is one of the androgens, produced both from adrenals and gonads. Androsterone can be reversibly converted to 3 alpha androstenediol. An elevated level of androsterone has cholesterol lowering effect. High levels of androsterone are frequently seen in female patients with acne with or without hirsuitism. Hirsute females without acne show normal levels of androsterone. Elevated levels of androsterone are shown in hyperthyroid patients. Lower levels of androsterone are seen in patients with myxedema and in cancer patients.
