Good article in the New York Times summarizing options for families with excess frozen embryos left over after IVF. It also covered the options for families considering embryo donation (also known as embryo adoption).
Embryo donation is becoming an increasingly popular option for families who have not been successful with IVF or adoption. The number of donated embryo transfers nearly doubled from 2009 to 2013, with 1.084 embryos being donated in 2013. Both donating and receiving families have options to consider. This article did a good job of covering these options.
