Of all the studies involving immature eggs, surely the most controversial--and, to some ethicists, downright repugnant--is the work on ovarian tissue. Researchers have been performing experiments aimed ultimately at transplanting such tissue from fetuses--either aborted or miscarried--into infertile women. Fetal tissue is a rich source of...
One of the most extraordinary offshoots of in vitro research is a technique, offered to people carrying severe genetic diseases, that can ensure that their children will not inherit their defective genes. Couples in this situation are not technically infertile, but their options have been limited to an uncertain pregnancy...
There is also the fear that PGD will be misused to make "perfect babies" by selecting for genetic traits that have nothing to do with disease. Genes have not been found for good looks, high IQ or artistic talent, but if they ever are, prospective parents are sure to want...
It may be years before the wizards of biomedical science will know if they can match these impressive results. The science of aging, though progressing rapidly, is still in its infancy, and scientists need to know a lot more about how the body's mechanisms work. For many years the...
