Multifactorial analysis of predictors of in vitro fertilization efficiency at the stage of embryo implantation

Objective: to identify the factors favoring successful implantation of embryos in IVF and ET. Material and methods. Using binary logistic regression method, the obtained data of 317 IVF/ICSI and ET cycles, implemented in accordance with current standards, were analyzed. Results. In the comparison groups, formed depending on the presence or absence of implantation in IVF/ICSI and ET, significant differences were revealed in regard to reduction indices of ovarian reserve, the total number of oocytes retrieved, number of M2 oocytes retrieved, number of fertilized oocytes, total number of obtained embryos, blastocysts, the number of high quality embryos, number of embryos transferred, the time of embryos transfer into the uterine cavity. Using binary logistic regression method, positive (anteroposterior uterus size, the number of high quality embryos, extended embryos cultivation up to 5 days) and negative (patient's age, diminished ovarian reserve, arcuate uterus) predictors of embryo implantation stage in IVF/ICSI and ET programs were defined.
