40 years, 7M babies after first ‘test tube,’ science is still raising moral questions
BROOKLYN, N.Y. — Esther Friedman held the Book of Psalms with both hands as she peered over her glasses at the fertility lab monitor. There were eight beautiful round eggs, retrieved from a young woman earlier that day.
“A good number,” Friedman said, nodding.
A technician grabbed a long glass tube, filled it with sperm and, within a few minutes, the eggs were fertilized. Eight potential new lives had just been conceived.
Friedman — an Orthodox Jewish rabbinical observer hired by the prospective parents — took a step back, lowered her eyes and began to pray.
Forty years ago this July, the world’s first “test tube” baby was born at a British hospital in the industrial city of Oldham, heralding a radical change in the creation of human life. Until Louise Joy Brown arrived, hopeful parents had been at the mercy of fate, and a barren marriage could feel like divine punishment.
Afterward, as one of the doctors involved in Brown’s birth put it, it seemed that science — not God — was in charge.
Since then, in vitro fertilization, or IVF, and related technologies have produced some 7 million babies who might never have existed — roughly the combined population of Paris, Nairobi and Kyoto — and the world’s fertility clinics have blossomed into a $17 billion business.
The procedures have amplified profound questions for the world’s theologians: When does life begin? If it begins at conception, is it a sin to destroy a fertilized egg? What defines a parent? Is the mother the woman who provides the egg or the woman who gives birth? What defines a marriage? If a man’s sperm fertilizes an egg from a woman who is not his wife, does that constitute adultery?
The moral questions are rapidly becoming more complex. Researchers are working to advance gene-editing tools that would allow parents to choose or “correct for” certain preferred characteristics; to create artificial wombs that could incubate fetuses outside the body for nine months; and to perfect techniques to produce “three-parent” babies who share genetic material from more than two people.
The risks, both scientific and moral, are enormous — particularly with gene editing, which could be used to produce babies with superhuman eyesight, speed and intelligence. “Off target” effects could result in fundamental changes not just to human bodies but to human nature.
Some religious leaders have objected to using gene editing on embryos or in ways that could affect future generations, arguing the human genome is sacred and editing it violates God’s plan for humanity. The U.S. National Academies of Sciences, Engineering and Medicine have invited religious critiques of the technology, and the Vatican is convening meetings to discuss its moral implications, including one this week in Rome.
On the guest list is Harvard geneticist George Church, who helped launch the Human Genome Project to map human DNA and is part of a team that announced plans in 2016 to use the gene-editing tool CRISPR to create synthetic human genomes to advance medical research. Church said he believes critics from the faith community will come to accept gene-editing technology, just as religious leaders eventually adapted to the discoveries of Galileo, Copernicus and Darwin.
“In the Bible, it says we are given dominion over the Earth,” Church said. “Inventing newer and newer advanced technologies is almost a key component of human nature.”
Most major religions have indeed come to tolerate — and even embrace — IVF, which was originally viewed with equal alarm. But the increasingly commonplace procedure is still condemned at the highest levels of the Catholic Church.
“Technology is a great thing, but technology does change us,” said the Rev. Michael J.K. Fuller, executive director of the Secretariat of Doctrine and Canonical Affairs for the U.S. Conference of Catholic Bishops. “At some point, we need to ask — how much is it changing us, and is that a good thing?”
The world’s 7.6 billion people practice an estimated 4,200 religions, each with various ideas about the soul and human destiny. So when British scientists Patrick Steptoe and Robert Edwards helped produce the first IVF baby on July 25, 1978, the event was viewed through heavy filters of wonder and suspicion.
Newspaper and TV reports recognized the birth of a child conceived in vitro — literally “in glass” — as a milestone in human history, akin to Neil Armstrong’s walk on the moon. London’s Evening News declared little 5-pound, 12-ounce Louise Brown a “Superbabe.” Newsweek compared her birth with a “first coming.” The New York Daily News wondered, “Test tube birth: a blessed event?”
Some faith leaders — especially Catholics — expressed grave misgivings and concern that the birth was unnatural, immoral and possibly dangerous. Some wondered whether children born through IVF might be superhuman or exceptionally frail or plagued by unforeseen defects introduced by the process.
Brown’s parents, who had been trying to conceive for nine years, saw divine intervention.
“Louise is, truly, a gift from God,” Lesley Brown tearfully told reporters. Her husband, John, added: “I am not a religious man, but I thank God that I heard our little girl cry for the first time.”
Steptoe emphasized the mundaneness of the science, arguing he was neither a wizard nor Dr. Frankenstein.
“We have merely done what many people try to do in all kinds of medicine — to help nature,” Steptoe said. “We found nature could not put an egg and sperm together, so we did it.”
Edwards, who won the Nobel Prize for medicine in 2010 for the breakthrough, was more direct in challenging critics in the religious establishment. In a rare interview in 2003, he told the London Times the experiments were “about more than infertility.”
“I wanted to find out exactly who was in charge, whether it was God Himself or whether it was scientists in the laboratory,” he said.
He was confident of the answer: “It was us.”
Numerous research teams quickly set out to replicate the breakthrough. Candice Reed, Australia’s first IVF baby, was born in 1980. Elizabeth Jordan Carr, the first American, followed in 1981.
In those early years, scholars from the world’s major religions expressed uneasiness about IVF. Some faith communities were quicker to accept assisted reproduction — including within the Hindu, Buddhist and Protestant traditions. In other places, many couples were left waiting for a signal from religious leaders.
Egypt’s Gad El-Haq Ali Gad El-Haq, a grand imam, was among the first major Muslim leaders to take a clear stand. In 1980, he issued a fatwa, or ruling, permitting IVF and similar procedures, so long as they involved a husband and a wife and no eggs or sperm from a third party.
The grand imam compared sterility with a disease and — noting the prophet Muhammad spoke of the need to seek remedy for disease — concluded IVF is permissible as a cure.
If a “trustworthy physician recommends in vitro fertilization and shall be responsible for its appropriateness, then it is permissible and obligatory as a treatment of a woman who has pregnancy impediments,” El-Haq wrote, according to a translation published by Marcia Inhorn, a Yale medical anthropologist.
Nearly two decades later, Ayatollah Ali Khamenei of Iran weighed in, loosening restrictions further for his Shiite Muslim followers. For example, men were permitted to engage in “mut’a” marriage to egg donors — a temporary union — to take advantage of technological advances without the taint of adultery.
Today, IVF is a widely accepted intervention in the Muslim world, and El-Haq’s fatwa is prominently displayed on many clinic walls.
The Vatican saw things differently. When Louise Brown was born, Cardinal Albino Luciani, who would soon become Pope John Paul I, congratulated her parents and wished the baby a happy and blessed life. He also said IVF raised many questions that would require a deeper moral response.
Nine years later, in 1987, the church issued the “Donum Vitae” (the Gift of Life), a guidance document on biomedical issues that has become the definitive Catholic teachingon IVF. In it, the church divided fertility treatments into two categories: Those that help achieve pregnancy through sex — fertility drugs, ovulation charts, surgery to remove blockages — are moral. Those that replace sex with technology, including IVF and artificial insemination, are immoral.
The division reflects the church’s view that the physical expression of love within marriage is godly and that sex alone can produce a child who is loved unconditionally as a person independent of the parents’ will and desires. Techniques like IVF end up “producing” a child in a lab where the parents are completely absent.
“The birth of a baby is always reason for joy. But the question was, what did they do to get there, and what does that mean?” said Richard Doerflinger, a scholar who recently retired from the U.S. Conference of Catholic Bishops, where he served for 36 years as a liaison to Congress on bioethics.
The other primary objection to IVF involves the treatment of fertilized eggs as “products” in a marketplace, as well as their routine creation and destruction. The church teaches that life begins at the moment of conception, and it has condemned the destruction of embryos as an evil on par with abortion and euthanasia.
Despite his liberalism on some issues, the current pope has been unwavering on the subject.
“We are living in a time of experimentation with life. But a bad experiment,” Pope Francis said in 2014 shortly after he was elected to his position. “Making children rather than accepting them as a gift, as I said. Playing with life. Be careful because this is a sin against the Creator.”
Much like church teaching on contraception, the guidance on IVF is out of step with public opinion in the United States. The Pew Research Center found in 2013 that, while Americans are divided on the morality of abortion, nearly 80 percent of U.S. adults consider IVF morally acceptable or not a moral issue — a finding that holds regardless of gender, political affiliation or religion.
John Grabowski, director of moral theology at Catholic University, acknowledged “a disconnect between official church teaching and Catholics’ practice.”
In interviews, Catholic couples who have undergone IVF said they felt a successful birth had been blessed by God or was otherwise “meant to be.”
