Time-Lapse Embryo culture: A better understanding of embryo development and clinical application.

Conventional embryo assessment is performed by removing embryos from incubators at least once a day. However, it is static and limited to specific time points, reducing the amount of information that could potentially be obtained. Fortunately, the time-lapse system is a powerful technology that enables to observe embryo development progression by image acquisition at recurrent time intervals, without interfering in the culture conditions.

What advice should we give our patients to preserve their fertility and avoid needing oocyte donation in the future? - A Social Fertility Preservation program.

Objective: To describe our fertility preservation program focusing on the number of oocytes vitrified by age.

Methods: From January 2015 to December 2016, 686 oocyte vitrification cycles were performed in our units for the social fertility preservation program. In total, 288 were donors who donated their oocytes for our oocyte-banking program, and 398 were patients who underwent elective fertility preservation.

The number of biopsied trophectoderm cells may affect pregnancy outcomes.

Objective: To study if the number of trophectoderm (TE) biopsied cells has an impact on implantation rates.

Design: A retrospective cohort study in a single-center study.

Setting: In vitro fertilization center.

A healthy HLA-matched baby born by using a combination of aCGH and Karyomapping: the first latin american case.

PGD for HLA typing is a procedure that can be performed when an affected child requires a transplant to treat a non-hereditary disorder related to the hematopoietic and/or immune system. Hematopoietic stem cell transplantation from an HLA-identical donor provides the best treatment option. Three conventional ovarian stimulation procedures for IVF were performed in a couple with a 10-year-old child diagnosed with T-cell acute lymphoblastic leukemia of high risk.
