Patient's question:
I have been married for several years and have not been pregnant. Recently, I went to the hospital for a check-up and found that my fallopian tubes are blocked. The doctor recommended that I undergo IVF. I heard that only one blastocyst can be transferred during the blastocyst transfer. Is it true that only one blastocyst can be transferred during IVF blastocyst transfer?Doctor's answer:
Embryo transfer in IVF can only involve one blastocyst. The blastocyst in IVF is an embryo that has developed for 5 to 7 days. The culture time is relatively long, the cells divide more, and the structure tends to be more stable, making it more in line with the natural laws of reproduction. During the blastocyst culture process, embryos with higher implantation potential are selected. Therefore, in IVF treatment, single blastocyst transfer is performed because it has a higher success rate.
