| Abstract: | Objective To investigate the real correlation between embryo density and developmental outcome of cleavage embryos on day 3 by adjusting covariates.Methods Data of 1196 embryos from 206 couples undergoing in vitro fertilization and embryo transfer(IVF-ET)treatment were retrospectively analyzed.Embryos were hypoxia-cultivated in a fixed30μl microdrop in culture dishes.Embryo quality on day 3 was evaluated and proportion of good quality cleavage embryos on day 3 was used as the endpoint.Maternal age,paternal age,antral follicles,level of anti-mullerian hormone(AMH),type of infertility,controlled ovarian stimulation(COS)protocol,length of stimulation,number of retrieved oocytes,and type of insemination were chosen as covariates.Results A total of 1196 embryos were included and analyzed.Three embryo densities were routinely used:30μl/embryo[1 embryo/(30μl·drop)],15μl/embryo[2 embryos/(30μl·drop)]and 10μl/embryo[3 embryos/(30μl·drop)].The number of embryos assigned into these three groups were 434,646 and 116 embryos separately.The average proportion of good quality embryos on day 3 in 10μl/embryo group were lower than that in both 15 and 30μl/embryo group(29.31%vs 40.25%,P<0.05;29.31%vs 42.17%,P<0.05),and it was comparable between groups of 15 and 30μl/embryo(40.25%vs 42.17%,P>0.05).In the regression analysis,without adjusting any covariables,the good quality embryos rate on day 3 of the 10μl/embryo group was 43%lower than that of the 30μl/embryo group(0.57,95%CI 0.32,1.03),and there was no statistical difference(P>0.05).In the minimum-adjusted model 2(adjusted the level of AMH and type of insemination),proportion of good quality embryos on day 3 in group of 10μl/embryo significantly decreased by 51%(0.49,95%CI 0.27,0.90,P<0.05)compared with that in group of 30μl/embryo.Conclusion In a 30μl microdrop,compared with individual cul turing,group culturing with the density of 10μl/embryo did not benefit the development of the cleavage embryos and 30μl/embryo was the optimal embryo density. |
