摘要
Abstract
Objective To investigate the influential factors of clinical pregnancy outcomes of women receiving natural cycle frozen-thawed embryo transfer. Methods Non-conditional Logistic regression analysis was conducted on the clinical data of 282 cases receiving natural cycle frozen-thawed embryo transfer during the period of January 2011 to December 2013 in Nanjing Maternal and Child Health Hospital. Results Patient’ s age, ovulation ( happened within 24 hours after hCG intramuscular injection ) and embryo at different stage were correlated with pregnancy outcomes (partial regression coefficient was -0. 052, 0. 446 and -0. 081, respectively, all P <0. 05). Duration of infertility, endometrial thickness and the number of embryo transplantation had no relation with clinical pregnancy outcomes (all P>0. 05). Cases whose ovulation happened within 24 hours after hCG intramuscular injection got higher clinical pregnancy rate than that of the cases without hCG injection and those whose follicles discharged within 48 hours after hCG injection (χ2 value was 3. 880 and 4. 660, respectively, both P<0. 05). Besides, blastocysts were easier to grow compared with embryos at cleavage stage. Conclusion Age, the timing of ovulation and embryo at developmental stages are the key influential factors of natural cycle frozen-thawed embryo transfer.关键词
