For example, embryologist Jacques Cohen, scientific director at the Institute for Reproductive Medicine and Science of Saint Barnabas in Livingston, New Jersey, has developed a procedure called cytoplasmic transfer that shows promise for assisting women approaching their early forties who either can't get pregnant through in vitro fertilization or have embryos of such poor quality they don't survive.

«What these results demonstrate is that a relatively short dietary disruption in nutrients that are available can have an impact on the ovary, the quality of the egg that the ovary produces, and the quality of the embryo and placenta that the egg develops into after fertilization,» Diaz said.

If you believe, for example, that granulosa cells and other very early features of ovarian ecology set up the polarities that ultimately determine the quality of a human egg, as Albertini does, then certain techniques widely used in IVF may be subtly perturbing the very mechanisms that eggs use to establish a plan to build an embryo and maximize the chances that it will develop properly.
