criopreservacion-ovocitos

Egg freezing by vitrification and later preservation in liquid nitrogen (-196ºC) has replaced slow freezing, which was less effective in terms of survival.

Oocyte vitrification is the ideal technique for women who are concerned about fertility preservation. It is also possible to preserve the eggs when the male is unable to provide a semen sample during an IVF cycle, making them available without having to do another cycle.

At FIVMadrid, the post-thaw egg survival rate is over 80%.
