The 5-cm long endpiece of a soft Nelaton's catheter, ch 6-8, splinted with a rigid polyethylene cannula, proved to be a suitable instrument for intrauterine homologous inseminations. Sixty couples were treated; indications for intrauterine insemination were subfertile semen, poor postcoital test, antisperm antibodies in male or female, and unexplained infertility of more than 5 years. Seventeen pregnancies occurred, that is 28%. The best results were obtained in the group with unexplained infertility and in the group with poor postcoital tests, combined with a good result of the in vitro sperm penetration tests. Complications of the inseminations were rare. The method did not elicit sperm agglutinins in the female; however, if sperm agglutinins were already present in the female, the titre level increased after the intrauterine inseminations.
用一根6-8号的柔软内拉通导管，其5厘米长的末端用硬聚乙烯套管加以支撑，结果证明这是一种适用于宫内同源人工授精的器械。对60对夫妇进行了治疗；宫内授精的指征包括精液不育、性交后试验结果不佳、男性或女性存在抗精子抗体以及不明原因的不孕超过5年。共发生了17例妊娠，即妊娠率为28%。在不明原因不孕组以及性交后试验结果不佳且体外精子穿透试验结果良好的组中取得了最佳效果。人工授精的并发症很少见。该方法在女性体内不会引发精子凝集素；然而，如果女性体内已经存在精子凝集素，那么宫内授精后其滴度水平会升高。
