Abstract
Objective To compare the application effect of vitrificative thawing and slow thawing in thawing transfer of programmed frozen embryos.Methods A total of 150 infertile patients who underwent thawed embryo transfer in the Department of Reproductive Medicine,Beijing Haidian District Maternal and Child Health Hospital from February 2021 to October 2023 were selected as the research objects.They were divided into control group(75 cases,slow thawing)and observation group(75 cases,vitrificative thawing)by random number table method.The embryonic development,resuscitation,transfer,and clinical pregnancy rate were compared between the two groups.Results The index of embryonic development situation was compared,there was no statistically significant difference between the two groups(P>0.05).The recovery integrity rate and recovery availability rate of the observation group were higher than those of the control group,and the differences were statistically significant(P<0.05).There was no significant difference in the number of transplantation and the number of transferred embryos between the two groups(P>0.05).The clinical pregnancy rate in the observation group was 58.67%(44/75),higher than that in the control group 41.33%(31/75)(P<0.05).Conclusion The application of vitrificative thawing in the thawing transfer of programmed frozen embryos can improve the rate of embryo recovery and clinical pregnancy.关键词
