O-078 Predictive factors of autologous Oocyte Post-warming Survival rate

AbstractStudy questionAre there any clinical or paraclinical predictive factors of Oocyte Post-warming Survival (OPS) rate?Summary answerWoman age, Body mass Index, estradiol level on triggering day and estradiol/oocyte ratio are critical predicting factors that should be considered before performing oocyte vitrification.What is known alreadySince the development and the validation of oocyte vitrification, we vitrify oocytes in different medical situations for patients who benefit ICSI. Although the OPS rate in our centre is satisfying, occasionally, it happens to be lower. OPS is dependent on quality of oocyte as demonstrated by the difference of OPS in oocyte donation/autologous cycles. The present study questions the existence of clinical and paraclinical factors predicting in OPS. In order to tackle this issue, we have assessed several parameters related to the woman and to her response to hormonal treatment known to influence oocyte quality in relation to OPSStudy design, size, durationA retrospective observational study of 786 autologous oocyte vitrification cycles was performed from October 2011 to July 2018 in 5 situations: cycles where only a part of mature collected oocytes were vitrified [1] Partial oocyte vitrification program(n  = 605), [2] Patients opposed to embryo cryopreservation(n = 2) and oocyte freeze-all cycles for the following reasons [3] Uncontrolled Ovarian hyperstimulation( = 89), [4] Unfavorable uterine environment/receptivity(n = 71) an...
