Abstract
A comparative study was made of four intrauterine contraceptive devices: the Nova-T, MLCu250 Short, MLCu375, and the Gyne T. An endometrial biopsy was performed on the 25th day of the menstrual cycle. The tissue obtained was analyzed to determine estrogen and progesterone receptor concentration. After two years of IUD use, both estrogen and progesterone receptors decreased proportionally to the increased amount of copper in the IUD.
摘要
对四种宫内节育器进行了一项对比研究
Nova-T、MLCu250 Short、MLCu375和Gyne T。在月经周期的第25天进行子宫内膜活检。对获取的组织进行分析以确定雌激素和孕激素受体浓度。使用宫内节育器两年后，雌激素和孕激素受体均随着宫内节育器中铜含量的增加而成比例下降。
