In the study that was recently published in the BioMedicine Online journal, a group of authors from Rome reported a significant increase in pregnancy rate in the combined transfer of embryos obtained from fresh and thawed oocytes. Fresh eggs were obtained in a natural cycle at the same day when another eggs, obtained after stimulation during previous IVF procedure, were thawed. They were fertilized them on the third day after the transfer of embryo into the uterus. The pregnancy reached 60% in cycles where the embryos are transferred from fresh and thawed oocytes and 17% in cycles, where an attempt to get a fresh oocyte failed and only thawed embryos were transferred. In our clinic for over 2 years we have applied techniques of combined transport of fresh and thawed embryos. In contrast to the Italian colleagues, we cultivate the embryos until the blastocyst stage, and the pregnancy rate after combined transfer is 83%.
