That may explain why IVF success rates are so variable; why, though two couples may produce an equal number of healthy embryos, one becomes pregnant while the other doesn't. "Using only these four factors, we can predict pregnancy with an accuracy of 70%," says Dr. Mylene Yao, professor of obstetrics and gynecology at Stanford and lead author of the study. "And it's extremely interesting that the four factors do not actually relate to the embryos that are transferred to the womb. So while it's still important to identify the best embryos for transfer, this suggests that...
While fertility specialists have long known about these factors and their role in predicting IVF success, Yao and her team have set out to determine which ones matter most - and how each factor affects the others in individual cases. For instance, doctors know that older women in general have a more difficult time conceiving. But Yao believes it should be possible to better predict whether a woman in her 40s will get pregnant through IVF based on the overall quality of the embryos she and her partner produce. Doctors already use their own algorithms for determining a couple's chances...

By the time he realized the tech world was quickly shifting from PCs to the network that connected them, his moves were limited. A fiercely competitive man, he reached for the obvious lever, and attempted to tie the late-starter Internet Explorer browser to the monopoly he created, the Windows operating system. The move was mercilessly effective and beat back rival Netscape, which immediately saw its commanding share of the browser market disappear...
