Cryopreservation/Embryo Freezing

This method has been performed at our center since 1990 and is indicated in cases where a surplus of embryos   in excess of the IVF program’s limit for transfer are available, or  when adverse maternal conditions arise before transfer

In the use of cryopreservation, surplus embryos  are stored  for thawing and transfer in a subsequent cycle.

Development of techniques for cryopreservation of human gametes and embryos over the past 30 years have expanded the capabilities and efficiency of infertility therapies.

Cryopreservation has become an integral component of a program for IVF and embryo transfer.
The alternative method of vitrification, for embryo freezing,  has been in use at our center since the beginning of 2005.
