Whites Have Black Twins in In-Vitro Mix-Up

By SARAH LYALL

ONDON, July 8 — A white couple have become the parents of black twins after a mistake by a fertility clinic during in-vitro fertilization in what appears to be the first case of its kind in Britain.

The mix-up was first reported today by the newspaper The Sun. In response, the High Court issued an injunction forbidding the publication or broadcasting of details of the case.

The case also involves a black couple who sought treatment at the same clinic but did not have any children afterward. A court case this fall will address the question of who the legal parents are.

The government would not comment on the mix-up, which apparently occurred when both couples were treated at an undisclosed National Health Service clinic. The injunction issued today by the High Court forbids identifying the clinic, the twins or the parents publicly, as well as making public the details about the treatment they received.

In in-vitro fertilization, which is used by tens of thousands of couples in Britain each year, sperm from the father and eggs from the mother are mixed together in the laboratory. The embryos that develop — often more than one at a time — are then placed in the mother.

No genetic tests are carried out to ensure that the right embryos are implanted into the right woman, so fertility clinics rely on a complex set of checks to avoid mistakes.

In this case, The Sun reported, it is unclear whether the black couple's fertilized egg was mistakenly implanted in the white woman, or whether the black man's sperm had been used to fertilize the white woman's egg.

"Apart from being a tragedy for the parents involved, it is also a major embarrassment for the National Health Service," a health service official told The Sun. "Great steps have been taken to ensure that this sort of thing never happens. It must be a one in a million chance. The big problem now is, who are the real parents of the twins?"

In a similar case in New York in 1999, a 40-year-old white woman who gave birth to two children — one white and one black — after in-vitro treatment agreed to return the black child to his biological parents after it was determined that she had been implanted with the wrong embryo.

In 1993, a Dutch woman who gave birth to twins was astonished to find that one had much darker skin than the other. A year later, DNA tests revealed that the hospital had mistakenly mixed sperm from the woman's white husband with that of a black man from the Dutch Antilles. In that case, the woman kept both babies.

Doriver Lilley, 37, who had six years of in-vitro treatment and who also gave birth to twins, told the Reuters news agency today that she had dreaded such a mistake taking place during her own treatment. "It's always there in the back of your mind — what if they're not mine?" she said. "What if they put them on the wrong shelf?"
