In recent years, the demand for assisted reproduction procedures has increased considerably. Everything seems to indicate that this trend will continue along this same path, which forces professionals in the reproductive area to be up to date with the latest advances in technology and personnel preparation, with the sole purpose of offering patients better pregnancy rates. The current goal of assisted reproduction is to achieve pregnancy and that it comes to an end after the first transfer of a single embryo. This is a great challenge, since it implies the joint effort to ensure that the majority of our patients achieve the desired healthy baby at home. Therefore, for a few years we assumed this commitment and understood that the only way to achieve this goal was to use all the available tools that technology can offer us in the reproductive field.

Background: Preimplantation genetic screening (PGS) using comparative genomics hybridization  (aCGH) and single nucleotide polymorphism (SNP) technology has become a useful tool in assisted reproduction by improving clinical outcomes. Both techniques identify aneuploidies and chromosomal rearrangement. However, SNPs with Parental Support (Natera Inc.) give extra information of the aneuploidy origin either from the sperm or the oocyte. Objectives: To determine single aneuplodies rate in human embryos obtained by assisted reproduction using single nucleotide polymorphism microarray. Design: Retrospective study. Setting: Grupo PRANOR, Sede Monterrico, and Genomics Peru, Lima, Peru. Biologic material: Human embryos. Interventions: From 2011 to 2013, 105 patients underwent IVF/ICSI with SNPs and Parental Support. In total, 429 embryos were analyzed and records were reviewed. Main outcome mea...
