低促性腺激素性性腺功能减退症(HH)是一种由于促性腺激素释放激素或促性腺激素缺乏,导致性腺功能减退的遗传异质性疾病。先天性HH又称为特发性低促性腺激素性性腺功能减退症(IHH)。IHH合并嗅觉障碍者称为Kallmann综合征,无嗅觉障碍者称为n IHH[1]。在男性患者中常表现为小阴茎或小睾丸、阴毛和(或)腋毛缺如、少精或无精症、不育等[2]。目前有研究表明,低促性腺激素性性腺
Hypogonadotropic hypogonadism (HH) is a hereditary heterogeneous disease that results in hypogonadism as a result of gonadotropin-releasing hormone or gonadotropin deficiency. Congenital HH, also known as idiopathic hypogonadotropic hypogonadism (IHH). IHH combined with olfactory disorders are called Kallmann syndrome, and those without olfactory disorders are called n IHH [1]. In male patients often showed small penis or small testis, pubic hair and (or) armpit absence, such as oligospermia or azoospermia, infertility [2]. There are studies show that low gonadotropin gonadal
