Registro de inseminación artificial de la Sociedad Española de Fertilidad de los años 2012 y 2013

Introduction

The indications for intrauterine insemination using the partner's sperm (IUI-H) are currently the subject of debate. To follow the progress of the implantation and efficacy in daily practice is key to defining its current role within the human assisted reproduction techniques.

Material and methods

This descriptive study presents data from the IUI-H and intrauterine insemination by donor sperm (IUI-D) Register compiled by the Spanish Fertility Society (SEF) from the years 2012 and 2013. These data were compared with those of the previous 6 years. The SEF register is voluntary and collects data aggregated per clinic, monitoring more than 20% of these clinics in situ. Less than half (42.4%) of the clinics registered with the Spanish Health Ministry participated in the 2012 SEF registers, with 50.3% in 2013. A total of 28,596 cycles were analysed during 2012 (21,561 IUI-H cycles and 7,035 IUI-D cycles), with 29,550 being analysed during 2013 (22,025 IUI-H cycles and 7,525 IUI-D cycles).

Results

The overall pregnancy rates per cycle were similar to those obtained during previous years for IUI-H (2012: 12.4%; 2013: 12.6%) and for IUI-D (2012: 20.1%; 2013: 21%). In 2012 11.3% (303) were multiple pregnancies with IUI-H and 11.6% in 2013. The IUI-D multiple pregnancy rate was 13.2% in 2012 and 11.5% in 2013. Miscarriages occurred in 22% of the IUI-H pregnancies with a known outcome in 2012, and in 20.9% of the 2013 pregnancies. With IUI-D these values were 22.7% in 2012 and 21.8% in 2013.

Conclusions

IUI is a fully consolidated technique, with stable results in recent years, although this technique results in high number of multiple pregnancies in our country.
