Abstract
Introduction
This report shows the IVF/ICSI Registry activity of the Spanish Society of Fertility during 2012 and 2013.
Material and methods
Descriptive study of the data registered from 113 Spanish clinics during 2012, and 130 during 2013. An analysis was performed on IVF/ICSI cycles with own eggs (35,430 in 2012, and 38,591 in 2013), IVF/ICSI cycles from egg donation (7,605 in 2012 and 8,320 in 2013), frozen embryo replacement cycles (11,736 in 2012 and 14,255 in 2013), pre-implantation genetic diagnosis/screening cycles (2,744 in 2012 and 2,890 in 2013), and cryopreserved oocytes cycles (6,452 in 2012 and 8,056 in 2013).
Results
A total of 9,750 clinical pregnancies were reported in 2012 with IVF and own eggs treatment, and 9,775 in 2013 (37.9% and 37.3% pregnancy rate per embryo transfer, respectively), leading to 23.9% of multiple pregnancies in 2012 and 22.9% in 2013. By egg donation cycles, 4,569 pregnancies were obtained (53.3%) from a total of 8,571 fresh embryo transfers in 2012, and 4,607 (55.9%) from 8.238 in 2013, leading to 31,1% of multiple pregnancies in 2012 and 30,1% in 2013. In 2012, 568 (20.7%) pregnancies were obtained from 2,744 egg collections for PGD treatment, and 484 (16.7%) from 2,890 in 2013. The number of cycles performed with vitrified own eggs was 1,949 in 2012 and 2,899 in 2013.
Conclusions
Multiple pregnancy rates are still high. The data shows a significant increase of the number of cycles with cryopreserved oocytes. A high percentage of pregnancies are unknown, lacking data on their follow-up.
