Assisted reproductive technologies (ART) in Latin America: The Latin American Registry, 2011

Abstract

Background: This 23rd report represents the results of ART procedures performed during 2011 by 145 centers from 12 countries in Latin America. This is the second time the data was individually collected in a case-by-case modality. Methods: All centers reported their ART procedures electronically and their data was accepted after consistency checks were performed and an accreditation team certi-28,065 initiated fresh homologous ART cycles consisting of 4,089 in vitro fertilization (IVF) cycles; 23,976 Intra cytoplasmic sperm injection (ICSI); 6,909 frozen embryo transfers (FET) and 6,258 oocyte donations (OD), plus 14 cases of GIFT, which are not described in this report. Results: Thirty eight percent of ET in IVF/ICSI cycles were performed in women age 35-39 years, while 25% included in ICSI and IVF cycles were 20.7% and 23.9%, respectively. The multiple delivery rate in IVF/ICSI cycles grouped togeembryos were transferred, neither the CPR nor the propor-transferred. In OD cycles, twin and triplet deliveries were 28.5% and 1.6%, respectively. In FET cycles, twin and triplet deliveries were 17.8% and 1.4%, respectively. Multiple delidelivery and perinatal mortality. In cases of elective transfers, the DR was 19.8% with eSET and 35.8% with eDET.
