Comparison of implantation and pregnancy rate of cleavage and blastocyst embryos transfer in women infertility
Keywords:
Cleavage Stage Embryo, Blastocyst Stage Embryo, Implantation Rate, Pregnancy RateAbstract
This study aimed to comparison of implantation and pregnancy rate of cleavage and blastocyst embryos transfer in women infertility.
The retrospective study is performed in implantation and pregnancy rate in women infertility by fresh embryo transfer (fresh-ET) and frozen embryo transfer (FET) of women under 35 years and equal or upto 35 years old during 1 January 2010 - 31 December 2014.
In this study, the implantation and pregnancy rate of cleavage and blastocyst by fresh-ET of women under 35 years and equal or upto 35 years old is not signification different between both groups. However, the embryo transfer by FET found implantation rate significantly increase when transfer by blastocyst stage in group under 35 years (odd ratio = 2.260; p-value = 0.023) and equal or upto 35 years old (odd ratio = 1.943; p-value = 0.011) when compare transfer by cleavage stage but pregnancy rate is not different when transfer in 2 stage in both group.
This study found that FET in the blastocyst stage has significantly higher implantation rate than the cleavage stage in the woman under 35 years old and also in women at equal or upto 35 years old. For fresh-ET cycle, in the women under 35 years and equal or upto 35 years old, there are no different in implantation and pregnancy rate in blastocyst and cleavage stage transfer. So that we suggest that should select blastocyst stage in FET. These study may be beneficals for improve successed rate in the treatment of women infertility.
