Pregnancies and deliveries after transfer of human blastocysts derived from in vitro matured oocytes in in vitro maturation cycles.
A total of 82 patients underwent 106 cycles in which immature oocytes were recovered after hCG priming and transferred at blastocyst-stage. After transfer, the implantation rate was 26.8%, and the clinical pregnancy rate was 51.9%. We found that the oocytes retrieved after hCG priming in women with high risk of ovarian hyperstimulation syndrome in the in vitro maturation program can develop to blastocyst, and pregnancies can be established by transfer of the blastocysts.
