Imlpantation of the Embryo in the uterus.
A maximum of three embryos may be transferred into the uterus, if available.

Considering not only a higher chance to become pregnant after transfer of 2 or 3 embryos, but also the increase of the risk of a multiple pregnancy too. The transfer procedure is painless. The embryos are drawn up into a thin, flexible catheder which is then carefully and gently inserted through the vagina into the uterine cavity.
