A frozen embryo transfer first involves one of the cycles dedicated to the genetic mother.
Preimplantation genetic diagnosis ( PGD or PIGD) is the genetic profiling of embryos prior to implantation (as a form of embryo profiling ), [1] and sometimes even of oocytes prior to fertilization. PGD is considered in a similar fashion to prenatal diagnosis. When used to screen for a specific genetic disease, its main advantage is that it ...
