METHODS: Amenorrhea patients with elevated FSH: Primary amenorrhea 18 cases, secondary amenorrhea 171 cases and age matched controls with normal menstruation, 180 cases. The descriptive parameters were: estrogen, alkaline phosphatase, urinary excretion of calcium to creatine ratio, cortical bone mineral density at the right radius measured by single photon absorptiometry and trabecular bone mineral density at the lumbar vertebra body measured by quantitative computerized tomography. RESULTS: Average E(2) levels in amenorrhea patients is under 150 pmol/L with significantly higher alkaline phosphatase and urine calcium to creatine ratio values than the normal menstruation group. Cortical bone mineral density in the secondary amenorrhea group (655 +/- 69 mg/cm(2)) was significantly lower than that of the normal menstruation group (677 +/- 56 mg/cm(2), P展开更多
