New studies suggest it is not good for children to begin their lives in petri dishes.
In vitro fertilization, controversial in the 1970s, has had a
"happy ending," says New York Times contributor Robin
Marantz Henig. Really? It hasn't ended happily for the tens of
thousands of human embryos killed or frozen in test-tube
experiments, and it isn't ending happily for the test-tube
survivors born with genetic defects.
The Los Angeles Timesreported
in late January that a "pair of studies in the last three months
have linked in vitro fertilization" and other "assisted
reproductive technology" to a "fourfold to sixfold increased risk
for a condition known as Beckwith-Wiedemann syndrome, an overgrowth
disorder typified by children with enlarged tongues and other
organs. Other reports within the last year have spotted a possible
increase in Angelman syndrome, in which children have a spectrum of
problems including speech impairment and mental retardation."
The studies support exactly what the dismissed moralists of the
1970s argued: it is not good for children to begin their lives in
petri dishes. The authors of the studies "suspect that culturing
eggs and embryos in the lab may be behind the heightened risks,"
reports the Times.
"Researchers Richard Schultz and Marisa Bartolomei at the
University of Pennsylvania have found that small differences in the
amount of salt or amino acids used in the culture can cause certain
genes in the embryo to behave aberrantly -- turning on when they
should be off, or off when they should be on."
Traditional moralists predicted that moving reproduction from
marriage to science would undermine the dignity and sanctity of
human life. But these studies suggest a physical price is also paid
for moving reproduction into an unnatural setting. Abnormalities
are appearing in children conceived under abnormal
circumstances.
Which stands to reason: When scientists imitate nature in a lab,
they do so imperfectly. They are playing God, but without the
wisdom of God.
In a grim irony, the practice of culturing multiple embryos in
an attempt to find the least defective one may itself be causing
defects. This practice has meant that embryos are exposed to the
abnormal conditions of a lab for a longer period of time, creating
more opportunity for "subtle genetic errors" to creep in.
"Traditionally, embryos are implanted in the mother after a day
or so in culture, when the embryo has divided only a few times. In
the last few years, more clinics have been growing eggs for about
five days to produce an embryo known as a blastocyst -- in an
effort to select the best and sturdiest embryos and increase the
chances of a successful pregnancy," reports the Times.
"'This could potentially be exposing the embryos even more to
conditions that could have a long-term health impact,' said John
Eppig, senior staff scientist at the Jackson Laboratory in Bar
Harbor, Maine."
Discarded embryos, frozen embryos, deformed embryos, children
who are afflicted with genetic disorders because they were cultured
in a lab -- boy what a "happy ending."
Henig says that "most predictions" about in vitro fertilization
-- "that the child's unnatural start would lead to genetic
complications we couldn't even imagine. That making a barren couple
fertile in this artificial way was an act of hubris for which the
couple, the scientists and society would have to pay. That in
animals, hundreds of attempts were needed before the first success,
so any human investigation would require hundreds of failures and
hundreds of potential embryos tossed down the laboratory sink. That
the experimental animals born this way suffered a chromosomal
abnormality or aged prematurely or contracted cancer, even if they
seemed normal at birth" -- didn't "pan out."
Wrong. They all panned out. As America hurtles towards cloning,
dragging with it an ever-expanding class of laboratory cripples,
the critics of overweening, godless science look more prescient
every day.
