定义
无睾症是一种罕见的 46 XY 性腺发育障碍,其特征是先天性完全无睾丸组织,而患者的表型和核型均为正常男性。此外,小阴茎是无睾症患者的常见症状。典型的激素特征是促性腺激素(尤其是 FSH(卵泡刺激素))基础水平升高,睾酮浓度低,血浆睾酮对 hCG(人绒毛膜促性腺激素)给药反应不明显。GnRH(促性腺激素释放激素)刺激试验引起 FSH 和 LH(黄体生成素)水平长期升高。
A rare 46,XY disorder of gonadal development characterized by congenital complete absence of testicular tissue in an individual with an otherwise male phenotype and normal karyotype. In addition, a small penis is a frequent finding in anorchid patients. Typical hormonal characteristics are elevated basal levels of gonadotropins (especially FSH (follicle-stimulating hormone), low concentration of testosterone, and lack of increase of plasma testosterone in response to hCG (human chorionic gonadotropin) administration. The GnRH (gonadotropin-releasing hormone) stimulation test induces a prolonged increase in FSH and LH (luteinizing hormone) levels.
