Abstract

Introduction

The data from the National Register of Activity in Assisted Human Reproduction (RNA – Register SEF), for artificial insemination during 2016 and 2017 are presented.

Material and methods

The data for conjugal and donor artificial insemination (AI-C and AI-D respectively) collected by the RNA – Register SEF during 2016 and 2017 were analysed and compared with data obtained in previous years. Participation was mandatory for Spanish assisted reproduction centres and annual aggregate data was collected by centre and in situ monitoring was carried out at random on data provided by more than 15% of the participating centres. A total of 36,463 cycles were analysed in 2016 (24,130 AI-C cycles and 12,333 AI-D cycles) and 34,964 cycles in 2017 (22,199 AI-C and 12,765 AI-D cycles).

Results

No significant differences were observed in the overall gestation rate per cycle, either for AI-C (2016: 13.0%; 2017: 12.6%) or for AI-D (2016: 20.4%; 2017: 19.6%). In 2016, 10.4% of the pregnancies obtained through AI-C were multiple pregnancies. Similar figures (10.7%) were obtained in 2017. Similar results were observed in AI-D, where the multiple gestation rate was 11.8% in 2016 and 9.9% in 2017. In pregnancies obtained with AI-C, 18.5% resulted in miscarriage in 2016, and 18.9% in 2017. With the donor technique, 17.2% resulted in miscarriage in 2016 and 17.7% in 2017.

Conclusions

Despite a slight increase in the number of participating centres, a decrease is observed in the use of AI-C, but this trend does not occur with AI-D.

国家活动登记-西班牙生育协会登记的人工授精结果(配偶和捐赠者)。2016年和2017年

介绍了2016年和2017年人工授精国家辅助人类生殖活动登记册(RNA - Register SEF)的数据。材料与方法分析2016年和2017年RNA - Register SEF采集的夫妻人工授精和供体人工授精(AI-C和AI-D)数据，并与往年数据进行比较。西班牙辅助生殖中心的参与是强制性的，各中心每年收集汇总数据，并随机对超过15%的参与中心提供的数据进行现场监测。2016年共分析了36,463个周期(24,130个AI-C周期和12,333个AI-D周期)，2017年分析了34,964个周期(22199个AI-C周期和12,765个AI-D周期)。结果AI-C的每周期总妊娠率(2016年:13.0%;2017年:12.6%)或AI-D(2016年:20.4%;2017年:19.6%)。2016年，通过人工智能- c获得的妊娠中有10.4%为多胎妊娠。2017年也获得了类似的数字(10.7%)。AI-D的结果类似，2016年多胎妊娠率为11.8%，2017年为多胎妊娠率为9.9%。在人工智能- c妊娠中，2016年流产率为18.5%，2017年为18.9%。使用供体技术，2016年和2017年流产的比例分别为17.2%和17.7%。尽管参与中心的数量略有增加，但人工智能- c的使用有所减少，但人工智能- d没有出现这种趋势。
