作者用家兔研究了含铜宫内节育器或塑料宫内节育器对卵运输、分裂以及着床的影响。静脉麻醉下开腹,在双角子宫的一角,自子宫输卵管连接下5毫米处,用手术刀切开约1毫米长,插入宫内节育器并用缝线结扎固定。在对侧子宫角同样切开1毫米,放入宫内节育器后又立即取出作为假手术组。对照组为无手术处置的正常交配家兔。放置宫内节育器后第10天开始实验,在交配后的24、 48、 72 The authors used rabbits to study the effects of copper-containing IUDs or plastic IUDs on egg transport, division, and implantation. Open the abdomen under intravenous anesthesia, in the horns of the uterine horn, 5 mm below the uterine tubal junction, cut approximately 1 mm long with a scalpel, insert the IUD and ligate with the suture. In the contralateral uterine horn the same cut 1 mm, into the IUD and immediately removed as a sham group. The control group was normal matched rabbits without surgical treatment. The first 10 days after the IUD placement began the experiment, 24, 48, 72 after mating
