作者在引言中指出:精索静脉曲张是引起男性不育最常见的原因之一,健康年轻或成年男性的发病率为5%到23%不等,占所有不育男性的20%到40%。自从Mcleod检查一组200名患者发现95%的患者的精子形态异常后,已充分证实受精索静脉曲张影响病人的精液异常。许多作者已报道这种患者的精液中有典型的大量的锥形精子和不定型及不成熟的精子。许多研究者报道:精索静脉结扎后53%到92%的病例的精液质量得到改善和20%到55%的病例的妊娠率提高。最近,Comhaire注意到:精索静脉回流(亚临床型精索静脉曲张)而不是存在可触及的膨胀的蔓状丛,即可引起Sertoli细胞的功能障碍,导致少精子及活动力降低并且异常精子数目增加。Gonzaler等和Boucher等也报
In the introduction, the authors point out that varicocele is one of the most common causes of male infertility, with the incidence of healthy young or adult males ranging from 5% to 23%, accounting for 20% to 40% of all infertile men . Sperm abnormalities have been well documented in patients affected by varicoceles since a set of 200 patients with Mcleod’s findings of sperm morphology abnormalities in 95% of patients. Many authors have reported that this patient’s seminal fluid is typically large in number of conical sperm and unsorted and immature sperm. Many investigators report that semen quality is improved in 53% to 92% of cases after varicocelectomy and in pregnancies in 20% to 55% of cases. Recently, Comhaire noticed that instead of having palpable expanded bullae, spermatic venous reflux (subclinical varicocele) can cause dysfunction of Sertoli cells resulting in reduced sperm and motility and abnormal sperm The number increased.
