Morphokinetic parameters as auxiliary criteria for selection of blastocysts cultivated in a time-lapse monitoring system.

Objective: To describe embryonic profile up to blastocyst stage in a time-lapse system.

Methods: A retrospective, longitudinal, analytical study of patients submitted to in vitro fertilization. The embryos were grouped according to the degree of expansion, internal cell mass and trophectoderm classification, the morphokinetic parameters were associated with the time periods stated in each evolution phase.

Evaluation of growth hormone co-treatment in in vitro fertilization in patients responding better to the GnRH antagonist short protocol.

Objective: The present study aims at evaluating the results obtained after in vitro fertilization in bad responders, using controlled ovarian hyperstimulation together with the use of gonadotrophin releasing hormone (GnRH) antagonist (cetrorelix acetate) in a short protocol.

Methods: This is an analytical, longitudinal, retrospective and controlled study involving patients who underwent in vitro fertilization (IVF) procedures in the assisted reproduction program of the Reproferty clinic, in the municipality of São José dos Campos/SP, from January 2012 to December 2016. We collected the data obtained from the medical records of patients considered to have undergone controlled ovarian hyperstimulation using GnRH antagonist (cetrorelix acetate) and Growth Hormone (GH) in a short cycle protocol.
