"As evangelical Christians, Paul and Susan Lim believe that life begins at conception. So when they decided to have a third child, in vitro fertilization was out of the question, since the process often yields extra embryos.
"But “adopting” the frozen embryos of another couple who had gone through I.V.F. was not.
"Dr. Lim called it a “rescue operation.” To him, transferring donated embryos to his wife’s uterus was akin to saving a life. “These children are being abandoned in a frozen state,” he said. “If they don’t get adopted, they’re dead.”
"As I.V.F. becomes more widespread and the number of spare embryos rises, giving birth with donated embryos is becoming more popular, especially among couples who oppose abortion and are struggling with infertility. But many of the agencies that offer donated embryos, including a vast majority of those supported by federal grants, are affiliated with anti-abortion rights or Christian organizations, leading some people to question whether single people, gay couples and others who might be interested could be missing out.
"According to the Centers for Disease Control and Prevention, there were more than 260,000 attempts at I.V.F. in 2016, the most recent year for which data is available. Of those attempts, about 150,000 resulted in transfers of embryos. There is no reliable data on the number of frozen embryos in the United States, but experts estimate the total between 600,000 and one million.
Of the two million transfers of embryos to a woman’s uterus recorded by the C.D.C. from 2000 to 2016, only 16,000 were donor embryos. But over that period, the annual number of donor transfers rose sharply — from 334 in 2000 to 1,940 in 2016 — and experts say it is continuing to increase.
"National Embryo Donation Center, based in Knoxville, Tenn., is the largest embryo donation clinic in the country. It also requires potential families to be heterosexual couples who have been “married for a minimum of three years.”

Assisted Reproductive Technology National Summary Report for 2016
*Noted earlier: "Of the 263,577 ART cycles performed in 2016, 65,840 cycles (25%) were started with the intent of cryopreserving (freezing) and storing all
resulting eggs or embryos for potential future use. However, because this cycle type (a banking ycle) cannot result in immediate pregnancy, the 65,840 banking cycles started in 2016 are not included in the majority of this national report."
