Patients aged 35-37 years should first consider single-embryo transfer, and patients aged 38-40 years should receive single-blastocyst embryo transfers if euploid embryos are available, but no more than three cleavage-stage embryos or two blastocysts.
It is recommended that poor quality embryos be cultured separately and subsequently transferred or frozen if they could develop to high quality blastocysts.
The particular stem cells that will eventually make the future body, the embryonic stem cells (ESCs) cluster together inside the embryo towards one end: this stage of development is known as the blastocyst.
However, data on the development of sheep (Ovis aries) and cattle blastocysts in the presence of serum have raised serious issues regarding the use of serum for embryo culture.
The results showed that the blastocyst rates in injection 560 ng/uL Npm and 1000 ng/uL PGA groups were higher than those of other groups.
