输精管吻合术成功后妊娠率为12～60%,解剖上成功的吻合不一定使男子生育力恢复,对解剖上成功的吻合术后生育力低下的免疫学作用认识正在逐步提高。本文作者运用直接和间接免疫珠抗精子抗体试验对作输精管吻合术男子的免疫学状况进行了前瞻性研究。 55例作吻合术的男子的平均年龄40岁(30～55岁);输精管阻断时间平均10年(1～19年)。手术当天取血,在-120℃下保存与术后3～6个月取血的31例作间接试验;术后至少4个月后,取31例吻合术者的精液作直接试验。另外,对几种关系到输精管吻合能否顺利成功的因素,如有无精子肉芽肿,从输精管结扎术至吻合术时的间隔和管腔液中有无精子也作了评价。
Vaginal tube anastomosis after the success of pregnancy rate of 12 to 60%, anatomical success of the anastomosis may not be restored to the man fertility, anatomically successful anastomosis fertility immune function is gradually recognized. The authors conducted a prospective study of the immunological status of men with vas deferens anastomosis using both direct and indirect immunoglobulin antisperm antibody tests. The average age of 55 men who were anastomosed was 40 years (range, 30-55 years). Vasectomies were blocked for an average of 10 years (range, 1 to 19 years). Blood was collected on the day of surgery, and 31 cases were preserved at -120 ℃ and were taken from 3 to 6 months after operation. After the operation for at least 4 months, semen from 31 anastomosis patients were directly tested. In addition, several factors related to the success of vas deferens anastomosis, such as the presence or absence of sperm granuloma, vasectomy from anastomosis to the interval and the presence or absence of sperm in the lumen was also evaluated.
