Fertil Steril. 1992 Jun;57(6):1289-93.
To assess the role of varicocele in male infertility.
Data analysis of a large population of couples who were systematically investigated for infertility.
Couples were recruited in 34 World Health Organization collaborating centers in 24 countries.
Nine thousand thirty-four men presenting as partner of infertile couples.
None.
Physical findings, semen characteristics, coincidental pathology, and spontaneous pregnancies.
Varicocele was found in 25.4% of men with abnormal semen, compared with 11.7% of men with normal semen. It was accompanied by decreased testicular volume, impaired sperm quality, and decline of Leydig cell secretion. Spontaneous pregnancies were as frequent in couples in whom the men did or did not have varicocele.
Varicocele is clearly associated with impairment of testicular function and infertility.
评估精索静脉曲张在男性不育中的作用。
对大量因不育而接受系统调查的夫妇的数据进行分析。
在24个国家的34个世界卫生组织合作中心招募夫妇。
9034名作为不育夫妇一方的男性。
无。
体格检查结果、精液特征、合并病变及自然受孕情况。
精液异常的男性中25.4%患有精索静脉曲张，而精液正常的男性中这一比例为11.7%。精索静脉曲张伴有睾丸体积减小、精子质量受损和睾丸间质细胞分泌功能下降。男性患有或未患有精索静脉曲张的夫妇自然受孕几率相同。
精索静脉曲张显然与睾丸功能损害和不育有关。
