In this retrospective cohort study, infertile patients undergoing fresh IVF cycles between January 2006 and December 2016 at the Reproductive Medicine Center in Tongji Hospital were included. A total of 42,468 cycles were conducted. Propensity score matching was carried out to match the baseline characteristics, and participants were assigned to the PLGC group and control group. The main outcomes were pregnancy rate and live birth rate. Patient characteristics and clinical outcomes were compared before and after matching. In general, the fate of oocytes in the PLGC group was much worse than those in the control group after matching, including metaphase II rate, two-pronuclei rate, available embryo rate, blastocyst formation rate, high-quality blastocyst rate, pregnancy rate, implantation rate and live birth rate. Among those potential risk factors, gonadotrophin duration, oeerone elevation can reduce the occurrence of premature luteinization. Why are women who face poor prognoses for success in assisted reproductive technology (ART) treatment choosing to pursue procedures using their own eggs, despite receiving information that their chances of success are very low. Cross-sectional study based on an anonymous questionnaire distributed to women aged between 43 and 45 years, undergoing ART using their own oocytes, at six public outpatient fertility clinics and three public in-hospital IVF units in Israel between 2015 and 2016. The main outcome measure was personal estimation of chance to achieve a live birth after the current ART treatment cycle and the cumulative estimated rate after all the treatment cycles the patient intended to undergo. Response rate was 70.0%, with 91 participants of mean age 43.8 ± 0.7 years. Participants estimated their delivery rates after the next ART trea
