Plasma testosterone, luteinizing hormone (L.H.) and follicle stimulating (F.S.H.) were measured before operation in 39 males, aged 26 to 53 years with 2 to 5 children, seeking vasectomy for contraceptive purposes. These measurements were repeated at 3 and 12 months after vasectomy. Levels of L.H. at 12 months were significantly higher than pre-vasectomy levels, suggesting some degree of decreased Leydig cell function. However, testosterone and F.S.H. levels were similar at the three sampling times. Continuing yearly measurements for at least 5 years are planned.
对39名年龄在26至53岁、育有2至5个孩子、因避孕目的寻求输精管结扎术的男性，在手术前测量了血浆睾酮、促黄体生成素（LH）和促卵泡生成素（FSH）。在输精管结扎术后3个月和12个月重复进行这些测量。术后12个月时LH水平显著高于输精管结扎术前的水平，提示睾丸间质细胞功能有一定程度的减退。然而，睾酮和FSH水平在三个采样时间点相似。计划至少连续5年每年进行测量。
