抑制素B与男性生殖的研究进展

抑制素B是直接由睾丸分泌的二聚体糖蛋白激素,对多种外源性激素起反应。血清抑制素B水平受年龄、睾丸体积、青春期发生时间、标本采集时间、不同人群等多种因素影响。抑制素B能直接反映睾丸的精子发生,可作为临床评价男性生育力的重要指标。抑制素B的检测在男性不育病因诊断和监测放、化疗对男性生精功能的损伤及儿童隐睾症、精索静脉曲张治疗疗效评估方面有其应用价值。在辅助生殖技术中,抑制素B的检测对睾丸精子抽吸的结果有预测作用。

Advances in Researches on Inhibin B and Male Reproduction

Inhibin B, a dimeric glycoprotein, is directly secreted by the testis and responses to a diversity of exogenic hormones. Serum inhibin B levels will be influenced by different factors, such as age, testis volume, the time of puberty, the time of sample collection, varied groups of people and so on. Inhibin B is directly relevant to spermatogenesis of the testis and can be viewed as a valuable marker to assess male fertility. The determination of serum inhibin B has an applicable value in diagnosing the etiology of male infertility, assessing the damage to spermatogenesis in men after radiotherapy or chemiotherapy, and evaluating therapeutic effect on cryptorchidism and varicocele. Moreover, as far as assisted reproductive technology is concerned, the investigation of serum inhibin B has a predictive value in testicular sperm extraction. Natl J Androl,2005,11(4):299-302
