Current status of assisted reproduction in Latin America and the world.
 
"We invite all centres of REDLARA and new centres performing Assisted Reproduction procedures to report their data corresponding to the year 2015.
For further information, please contact: info@redlara.com or registro@redlara.com"
 
This Register reports 18.598 procedures of assisted reproduction performed in 102 centres accredited or affiliated to RED. From the 11 countries that perform these procedures, Brazil contributes with 49.3% of the procedures, followed by Argentine and Mexico with 19.8% and 9.7%, respectively. Each of the other countries contributes with less than 6% of the procedures.

During the year 2001, 13.971 follicular aspirations were performed, which generates 12.777 embryo transfers. From these procedures, 71.5% corresponds to ICSI, with or without Assisted Hatching, 28.1% to IVF and 0.4% to GIFT + others.

Taking IVF and ICSI as a set, the global pregnancy and birth rates by aspiration were 28.0% and 21.8%, respectively. The birth rate by aspiration is the highest got in Latin America.

From the total of the embryo transfers in IVF and ICSI, in 12% 1 embryo was transferred and in 19% 2 embryos. In 28% of the procedures, 3 embryos were transferred and in 41% 4 embryos or more. The media of embryos transfer, as in the year 2000, kept in 3.2 embryos.

The multiple gestation rate was 29.8% (22.1% twins, 7.7% triplets). This percentage is similar to the 30.2% (22.8% twins, 7.4% triplets) reported in the year 2000.

From the IVF and ICSI procedures performed during the year 2001, we got 3615 liveborn babies; 1856 unique (51.3%), 1236 twins (34.2%), 459 triplets (12.7%) and 64 quadruplets (1.8%). Thus, 48.7% of the living newborn child resulted from a multiple gestation.

The premature (= 36 weeks of gestation) and extreme premature (= 31 weeks of gestation) was 15.5% and 2.8%, respectively, for unique births, 55.5% and 9.5% for twins, 89.6% and 20.1% for triplets.

The perinatal mortality was 1.7% for unique births, 7.1% for twins, 9.1% for triplets and 50% for quadruplets or more.

76.8% of the embryos were cryopreserved in 48-72 hours, 18% in pronucleus stage and 5.2% in blastocyst stage. 1657 embryo transfers were performed with a birth rate of 12.9%.

On the other hand, the birth rate by transfer in oocyte donation with fresh embryos was 27.1%, decreasing to 13.2% when the embryos transferred were cryopreserved.

There is no doubt the most severe complication is the multiple gestation and its perinatal result. As the large centers (> 500 cycles) as the small ones (= 100 cycles) transfer an excessive number of embryos. It is urgent to incorporate strategies to facilitate the implementation of programmes with transfer of 01 or maximum 2 embryos in Latin America.
