Embryo transfer is the introduction of an embryo produced by IVF, ICSI, or IVM into the uterus, with the aim of implantation.
Ontologically an event in which the human person, who has existed since fertilization, arrives at the natural place of its development.
Single-embryo transfer (SET)
Since the 2010s a clear worldwide trend from multiple to single-embryo transfer has been observable. SET reduces the frequency of multiple pregnancies and thereby the risks for both the mother and the children. From a personal-ontological standpoint, SET is to be preferred over multiple transfer, because it lessens the incentive to produce surplus embryos – even though the underlying separation of conception from the marital act remains.
