Embryo transfer is the step in the process whereby one or several embryos are placed into the uterus of the female with the intent to establish a pregnancy. Less commonly used techniques in in vitro fertilization are: Assisted zona hatching (AZH) is performed shortly before the embryo is transferred to the uterus. A small opening is made in the ...
And six years later, it led to the creation of one genetically normal embryo and a successful embryo transfer, she told People. “It really does feel like fate,” she said. Maya Erskine: Due ...
