Abstract

Objective:Comparison of clinical outcome after cryopreservation of embryos obtained from intracytoplasmic sperm injection(ICSI)and in vitro fertilization(IVF).Methods : 142 frozen embryo transfer cycles between January 2008 and December 2008 were included.Of those,104 cycles were derived from oocytes fertilized by IVF and 38 cycles were derived from oocytes fertilized by ICSI.The clinical outcome of the two groups were compared.Results : A total of 375 embryos (275 in IVF group and 100 in ICSI group)have undergone a thaw cycle .The embryo survival rates were similar between the two groups(89.09% and 87.00%,IVF and ICSI respectively).There was no significant difference in pregnancy rates (38.46% and 34.21%)and implantation rates (21.22% and 24.14%)between the IVF and ICSI groups respectively.Conclusion : ICSI does not have an adverse impact on the survival and development potential of cryopreserved and thawed embryos.
