Resumen

SCHWARZE M, Juan E et al. Registro chileno de técnicas de reproducción asistida, 2011. Rev. chil. obstet. ginecol. [online]. 2014, vol.79, n.4, pp.340-346. ISSN 0717-7526.  http://dx.doi.org/10.4067/S0717-75262014000400014.

We present the Chilean Registry of Assisted Reproductive Technologies performed in 2011. For the first time this registry is performed on a case-by-case basis. Seven centres reported 1,918 cycles: 161 in vitro fertilisation cases (IVF), 1,366 intracytoplasmatic sperm injection cases (ICSI), 325 cryiopreserved embryo transfers, and 158 oocyte donation cycles. The delivery rate per oocyte pick up for IVF and ICSI cycles was 18.6% and 22.0%, respectively. The delivery rate per embryo transfers for cryopreserved embryo transfer and oocyte donation were 21.5% and 41.9%, respectively. The mean age of woman undergoing IVF/ICSI was 35.7 years (min 22 max 48 years); 38% of initiated cycles were performed in women aged ≤34 years. As in previous years, the mean number of embryos transferred declined slightly, reaching 2.1. The multiple delivery rate was 24%: 23% twin and 1% triplet and higher. In conclusion the delivery rate in IVF/ICSI cycles remains stable. Thanks to cryopreservation and posterior embryo transfer, the rate of triplet-delivery continues to diminish. However, the rate of twin delivery has not diminished, and remains a challenge.
