Abstract:
Objective To investigate the influence of infertility duration on the outcomes of frozen-thawed embryo transfer(FET)in women under 30 years old.Methods A retrospective analysis was conducted on 540 FET cycles at reproductive center.The cycles were categorized into clinical pregnancy and non-clinical pregnancy groups based on the occurrence of clinical pregnancy.Furthermore,patients were stratified into four groups based on infertility duration:Group A(1-2 years),Group B(3-4 years),Group C(5-6 years),and Group D(7-8 years).Differences in baseline characteristics and clinical pregnancy outcomes among the groups were analyzed.Results Baseline characteristics showed statistical significance only in age differences among the groups(P＜0.05),with no other significant differences.The clinical pregnancy rate(33.93％)and embryo implantation rate(25％)in group C were the lowest,but only the difference in clinical pregnancy rate was statistically significant(P＜0.05).Early miscarriage rates did not show significant differences among the four groups.Conclusion Infertility duration has a discernible impact significant impact on clinical pregnancy rate of FET in women under 30 years old.However,the effect does not linearly increase with longer infertility duration.
