Abstract

We retrospectively assessed IVF outcomes in 611 patients 648 cycles who underwent blastocyst frozen embryo transfer FET between January 2007 and December 2009 All embryos had been cryopreserved by a vitrification method following a previous IVF cycle Patients were prepared for transfer by using either the natural cycle n = 310/Group 1 the natural cycle with ovulation induction employing human chorionic gonadotropin n = 134/Group 2 or a hormonally manipulated artificial cycle with estrogen and progesterone supplementation n = 204/Group 3Multivariate logistic regression analysis showed a significant difference in clinical pregnancy rate between Groups 3 304 and 1 419 odds ratio OR 0567 95 confidence interval CI 0379–0847 P = 0006 whereas the difference between Groups 2 and 1 was not significant 418 vs 419 OR 0683 95 CI 0435–1073 P = 0098 Other significant variables affecting clinical pregnancy rate were the number of embryos transferred the grade of transferred embryos and maximal endometrial thickness
