Heterologous Embryo Transfer (“HET”) occurs when a woman, unable to conceive a child, has a genetically unrelated embryo implanted. This form of surrogacy, which has been used for over 30 years, is now being complicated by the trend of embryo adoption.
There are often surplus embryos left over when a couple uses assisted reproductive technology, such as in vitro fertilization. In certain situations, the couple will allow the surplus embryos to be adopted by another couple. However, this raises novel legal questions if an issue of custody arises. There is neither legislation nor court precedent addressing what would happen if the biological parents sought custody from the second couple. As embryo adoption continues to increase, there will surely be legal battles over this.

Excerpt from article:
Bringing a child into the world by traditional means is a process fraught with moral, ethical and emotional complications. Bringing a child into the world by non-traditional means, such as heterologous embryo transfer (HET) increases the complications exponentially, begging questions such as what defines a parent (genes, love, pregnancy and delivery, etc…) and who does the child belong to?
