Abstract

A 37-year-old woman was admitted for chief complaints about primary amenorrhea and multiple bone pains. She was raised phenotypically female but her chromosomal study was no-rmal male karyotype(46 XY). On pelvic examination, she showed relatively normal female ex-ternal genitalia except short blind-ending vagina. There were also no uterus and tubes in operation field. Even though rare disorder, she was diagnosed male pseudohermaphroditism due to 17-beta -hydroxysteroid dehydrogenase deficiency. This disorder is the most common enzyme defect in biosynthesis of testosterone and involves the last step. The serum level of sex steroid: test osterone, estradiol were decreased and FSH, LH were increased. Androstenedione was increased and we could obtain that Androstenedione / Testosterone ratio was increased. Because of 17-beta-HSD deficiency, estrogen was not converted to estradiol, and so estradiol was markedly decreased. Same as above, we experienced a case of male pseudohermaphroditism due to 17-beta-hydroxysteroid dehydrogenase deficiency with multiple osteoporosis. So we report this case with a brief review of literatures.
