Vitrification Brazil

It is the most advanced technology in the freezing of gametas and embryos.

The embryos transfer criopreservados increases very much the final efficiency of the only cycle of stimulation ovariana. In the CRH Prof. Franco Junior, the tax of clinical pregnancy with frozen embryos exceeds to 25 %.

When we talk in criopreservação about ova, at present this technique allows that the women do a stock of his ova before losing his function ovariana. On the other side, she also is indicated for the patients who need chemotherapy or radiotherapy, once that the fertility of these women can be affected by these agents.

The factors wrapped in the decision are great of postponing the motherhood: the professional stability, the wait for a stable relationship, the wish of reaching financial security, or, still, the uncertainty on the wish of being a mother. With the ova freezing, it is possible to preserve these cells to very low temperatures (196th C negatives) with the use of liquid nitrogen. In 2009, our team got the first gestation through this technique. For his realization, it is necessary that to patient pass for a process identic to that of the fecundation in vitro. The ovaries are stimulated, the ova collected, directed to the laboratory, dehydrated and frozen by the vitrification.
