"Medical groups representing U.S. fertility experts, alarmed by rising numbers of multiple births, on Tuesday advised limiting the number of embryos implanted in women undergoing in-vitro fertilization. The latest medical evidence "clearly indicates" that high pregnancy rates can be achieved even with fewer embryo transfers, Dr. Marc Fritz, chair of the American Society for Reproductive Medicine's practice committee, said in a statement. Some patients and clinics have opted for transferring several embryos during a single cycle in order to increase the odds of success but pregnancies involving two or more fetuses are at risk of complications including premature delivery, which increases a baby's odds of suffering medical and developmental problems.
The new recommendations to fertility specialists, which are not enforceable, call for transfer of no more than two embryos for women under age 35, and say the transfer of a single embryo should be considered." Reuters, Yahoo News Link to Article (last visited 10-25-06 NVS)
