fertilizable

"The eggs are there, but they are not active." Something about the stem cells seems "to activate these eggs to become fertilizable," he said.

Such eggs generally round up after time and are equally fertilizable, but this has not been tested directly.

Although the growth of in vitro preantral follicles can result in fertilizable oocytes and successful childbirth (9), the technique of In Vitro Maturation (IVM) needs to be further enhanced because GV oocytes have a reasonable ability to mature and reach the Metaphase II (MII) stage.

[beta]/[B.sub.o] reflects changes in gamete performance at different pH levels; these include, for example, the fertilizable area of the egg, the proportion of sperm able to fertilize an egg, or the number of sperm contacts needed to allow for the penetration of a single spermatozoan.

acuta were still fertilizable for up to 6 h after release, the age of the gametes for optimal fertilization is comparatively short.

In this arraignment the future social mother was able to produce fertilizable eggs but medically unable to carry a pregnancy.

Ever since the start of IVF, there has been a lot of modifications and improvements in ovarian stimulation protocols, to retrieve the maximum number of fertilizable oocytes in a given cycle.

The most likely reason is that follicular size cannot accurately predict the maturity of the oocyte within--follicles as small as 10 mm sometimes yield mature and fertilizable oocytes.

The graduate students and the fellows began talking about the inability of the lab to extend the experiment to see if human ovarian follicles are similarly capable of maturing into eggs that would be fertilizable. As the recipient of a grant from the National Institutes of Health, the lab must abide by the Dickey-Wicker Amendment, which bans federal funding for research involving human embryos and parthenotes.
