Frozen the intersection of ovum and pregnant success rate and freeze, fertilize embryo to be same
It is reported ' The easy reporter of reporter Lee's weather Gao Jian) Recently, a research thesis that what the Chinese Technology Association and China science and technology news learn to recommend together is published on " China's medical magazine " reveals, the medical workers of our country employ egg mother cell's frozen technology to assist and bear the test tube baby, have made and employed embryo's clinical pregnancy rate equally of frozen technology. This research has offered scientific basis for constructing the ovum storehouse in the actual meaning in our country.

In our country, the current regulation forbids embryos to donate, but allow the ovum to donate. Then, how is the pregnancy rate of frozen ovum? Do not as do embryos well first and then freeze the high success rate unfreezed? To play, puncture the women who fetches the ovum, accepts as to Ultrasonography B the artificial test tube baby bore, freeze the surplus ovum, or is made the surplus ovum into first and fertilized the embryo and frozen again? Which kind of method insures even more? Will it influence final pregnant success rate that the surplus ovum is frozen first? This one is by the country " 863" The research of the fund subsidy of project has answered these problems.

Researchers such as the clinical reproductive medicine center king of first affiliated hospital of Nanjing medical university,etc., January to will it be December 2007, 2006 until centre this accept in vitro fertilization and injection assist 258 women that bore to go on and divide into groups in the embryo transfer and single the intersection of sperm and the intersection of ovum and thick liquid, one group is embryo's frozen group, one group is egg mother cell's frozen group, relatively freezes unfreezing recovering rate and clinical pregnancy rate of ovum and frozen embryo. Found finally, did not have obvious difference to freeze the ovum and freeze the clinical pregnancy rate after the embryo was unfreezed. It means, women are after puncturing and fetching the ovum, the surplus ovum can be frozen, needn't make into and is fertilized the embryo, freeze.

Researchers point out, egg mother cell's frozen technology has better clinical applicability under our country's current medical regulation system, especially share in the egg mother cell to donate the respect to have better using value.
