Abstract :Aim: The aim of this study was to investigate the effects of the number of oocytes retrieved and rate of mature oocytes on IVF outcomes in single fresh embryo transfer. Materials and Medhods: Two main groups were formed regarding number of oocytes retrieved and mature oocyte rate. According to the number of oocytes retrieved in 561 IVF cycles, 0-5 insert ignore into journalissuearticles values(n=175); oocytes were determined as group 1, 6-10 insert ignore into journalissuearticles values(n=214); oocytes as group 2, 11-15 insert ignore into journalissuearticles values(n=121); oocytes as group 3 and 16 or more oocytes as group 4 insert ignore into journalissuearticles values(n=51);. Regarding mature oocyte insert ignore into journalissuearticles values(metaphase II, MII oocyte); rate, three groups were formed: group 1A insert ignore into journalissuearticles values(n=338); 76-100% mature oocytes, group 2A insert ignore into journalissuearticles values(n=150); 75-50% mature oocytes, and group 3A insert ignore into journalissuearticles values(n=73); less than 50% mature oocytes. Results: The number of oocytes retrieved was negatively correlated fertilization rate, whereas Β-hCG positivity and clinical pregnancy rates were observed to be better in the 6-10 oocytes group. The mean age, basal LH, and ovulation trigger day E2 levels, and fertilization rate were differed significantly between three groups of mature oocyte rate. Conclusion: In conclusion, MII oocyte rates in the cohort, regardless of the number of oocytes retrieved, did not affect IVF outcomes.
