ABSTRACT
OBJECTIVE:
To study the effect of freezing on early stage embryos derived from intracytoplasmic sperm injection (ICSI) or from IVF.DESIGN:
Prospective, controlled clinical study.SETTING:
Private IVF center. PATIENT(S) Sixty-seven consecutive patients undergoing frozen-thawed embryo transfer cycles. INTERVENTION(S) Early stage embryos were frozen, thawed, and transferred. MAIN OUTCOME MEASURE(S) Post-thaw survival, implantation and pregnancy rates. RESULT(S) We noted an 88% post-thaw survival rate, an 18% implantation rate, and a 52% pregnancy rate in the ICSI group and 81%, 11%, and 25%, respectively, with conventional fertilization. CONCLUSION(S) Early stage embryos (either zygote or 2-4 cells) derived from ICSI can be frozen with confidence and higher post-thaw survival and pregnancy rates can be achieved when compared with those from conventional IVF.
