To evaluate mesometrial transplantation of frozen-thawed ovarian tissue in rabbit and to choose the optimized fertilization method for oocytes retrieved from grafts by investigating the capability of oocyte fertilization and further development. Forty rabbits were divided into three groups randomly: control group, fresh tissues transplantation group and frozen-thawed tissues transplantation group. Three months after the transplantation, rabbits were stimulated with FSH and oocytes were retrieved 13 h after human chorionic gonadotropin (HCG) injection. Oocytes matured in vivo or in vitro were then fertilized by conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), followed by observation and evaluation of fertilization rate and blastocyst formation rate. Blastocytes embryos were transferred to pseudopregnancy rabbits to observe pregnancy rate and birth rate. There were no significant differences in the percentage of oocytes matured either in vivo or in vitro among the three groups. The fertilization rate, cleavage rate and blastocyst formation rate of in vivo-matured oocytes had no difference among the three groups, whether they were fertilized by IVF or ICSI. Significantly higher fertilization rates of in vitro-matured oocytes were observed with ICSI compared with IVF in each group. The blastocyst formation rate of in vitro-matured oocytes was significantly lower than that of in vivo-matured oocytes in each group. The birth rate of in vivo-matured oocytes was significantly higher than that of in vitro-matured oocytes, although the pregnancy rate was similar between them. Mesometrial transplantation of frozen-thawed ovarian tissue may provide favorable conditions for follicle development. Oocytes retrieved from mesometrial grafts can develop to the blastocyst stage and produce live offspring. ICSI can optimize the fertilization rate of in vitro-matured oocytes retrieved from grafts.
