Once again, reproductive medicine slows demographic decline in Spain

According to the NSI, there were 23,879 fewer babies born in 2018 than in 2017, and 9,532 fewer babies born in 2019 than in 2018. Every year since 1999, Spain’s demographics are the lowest. These rates would be even lower without the births resulting from the Assisted Reproduction techniques.

According to the statistical data of the National Registry of Activity-2018 SEF Registry that was recently published by the Ministry of Health and the Spanish Society of Fertility, in the year 2018 a total of 149,337 cycles of IVF and 34,100 AI’s were carried out, resulting in the birth of 37,094 babies, which represent 9% of the births in our country.

"This ever-growing rate shows the impact that reproductive medicine advances have had on Spain’s birth rate while also demonstrating the importance of sharing these statistics at conferences such as these,” explained Registry Coordinator Fernando Prados during the workshop that took place online this year.

Fewer multiple births and better embryo selection

In the 2018 statistics report regarding the total number of practiced techniques carried out in the 319 Spanish reproduction centers that perform treatments, multiple births have fallen to 13%, therefore placing Spain below the European average for 2017.

Preimplantation Genetic Diagnosis (PGD) is the treatment that has experienced the greatest growth with respect to the previous report and those of the past five years. In 2018, a total of 12,533 cycles of genetic analysis of embryos were initiated. This number surpasses the figures from the previous five years.

"Embryo selection is the key to reproductive success. If we identify the best embryo, the one with the most possibilities, we will achieve pregnancy sooner and one will be enough. The registry’s statistical data regarding the reduced number of multiple births and the increase in PGD’s tell us that the medical community is performing its duties, and the patients are becoming more aware of the importance of following the specialists’ recommendations,” explains Dr. Fabio Cruz of IVI Valencia.

Also rising in number are the amount of cryopreserved embryo transfers. There are many studies shared by research groups advising about the importance of correctly preparing the uterine endometrium before the transfer. This could be very advantageous for the embryo cryopreservation process.

“The registry results demonstrate the overall confidence in this approach, indicating that 26% of all embryo transfers in 2018 were performed after embryo thawing. At IVI we are pioneers in embryo and oocyte vitrification. Because of our investment in research and technology since 2008, the results we obtain with cryopreserved embryos and oocytes are comparable to the same procedures using fresh embryos and oocytes,” concludes Dr. Cruz.
