Assisted reproductive techniques in Latin America: the Latin American Registry, 2013

Abstract Multinational data on assisted reproduction techniques undertaken in 2013 were collected from 158 institutions in 15 Latin American countries. Individualized cycle-based data included 57,456 initiated cycles. Treatments included autologous IVF and intracytoplasmic sperm injection (ICSI), fr...

Description
Summary:Abstract Multinational data on assisted reproduction techniques undertaken in 2013 were collected from 158 institutions in 15 Latin American countries. Individualized cycle-based data included 57,456 initiated cycles. Treatments included autologous IVF and intracytoplasmic sperm injection (ICSI), frozen embryo transfers, oocyte donations. In autologous reproduction, 29.22% of women were younger than 35 years, 40.1% were 35–39 years and 30.6% were 40 years or older. Overall delivery rate per oocyte retrieval was 20.6% for ICSI and 25.4% for IVF. Multiple births included 20.7% for twins and 1.1% for triplets and over. In oocyte donations, twins reached 30% and triplets 1.4%. In singletons, pre-term births were 7.5%: 36.58% in twins and 65.52% in triplets. The relative risk for prematurity was 4.9 (95% CI 4.5 to 5.3) in twins and 8.7 (95% CI 7.6 to 10.0) in triplets and above. Perinatal mortality was 29.4 per 1000 in singletons, 39.9 per 1000 in twins and 71.6 per 1000 in high order multiples. Elective single embryo transfer represented only 2% of cycles, with delivery rate of 39.1% in women aged 34 years or less. Given the effect of multiple births and prematurity, it is mandatory to reduce the number of embryos transferred in the region.
