Embryo donation is one disposition option for users of in vitro fertilisation with remaining fresh or frozen embryos. It is defined as the giving—generally without compensation—of embryos remaining after in vitro fertilization procedures to recipients for procreative implantation or research. Most IVF users with supernumerary embryos make embryo donation decisions after completing their families or discontinuing use of in vitro fertilization. Recipients of embryos donated for procreative implantation typically plan to transfer fresh or frozen embryos into a prepared uterus in order to facilitate pregnancy and childbirth. Recipients of embryos donated for research typically use them for clinical training, quality improvement research, or human embryonic stem cell research. For procreative implantation Embryo donation for procreative implantation is a form of third party reproduction. Embryo donation can be anonymous (donor and recipient parties are not known to each other, and individuals have no ability to contact one another), semi-open (parties can interact via a third party, but do not share personally identifiable information in order to provide a layer of privacy protection), open (party identities and contact information are shared so the families can interact directly in various types of relationships), or ID disclosure (donor-conceived youth can request and receive donor contact information when the donor-conceived reaches the age of 18). Any children born from embryo donation for procreation would be biologically related to the gamete donors used when creating the embryos. This is the same principle as is followed in egg donation or sperm donation. Embryo donation or adoption Some use the term "embryo donation" to refer strictly to anonymous embryo donation, and "embryo adoption" to refer to an open relationship. Others use the terms interchangeably because, regardless of the relationship, a clinical assisted reproduction procedure is involved, and the recipient couple is preparing to raise a child not genetically related to them. Lawyers who assist those trying to acquire an embryo state the term "embryo adoption" is a misnomer because the transfer of an embryo is handled as property transfer. One newspaper article in 2005 asserted that abortion rights advocates, advocates of embryonic stem cell research, and members of the fertility industry object to referring to the transfer as an "adoption" because they feel it gives an embryo the same status as a child. Most doctors describe the process as "embryo donation". According to a CBS News article dated July 28, 2005,[full citation needed] the term "Snowflake baby" was
