Embryo Cryopreservation. Frozen Embryo Transfer Procedure
Embryo freezing is popularly known as Embryo Cryopreservation. It is the procedure of storing the unused embryos in liquid nitrogen at sub zero temperature for use in later treatment cycle or for donation.
Treatments such as IVF, ICSI and Egg donation often generate embryos that are surplus to the immediate requirements of the treatment. If these ‘spare’ embryos are of good quality they can be frozen and placed in storage by Embryo freezing.
IVF and related treatments normally involve stimulation of the ovaries to produce a number of eggs. We aim to fertilise all of the eggs removed in order to have a selection of embryos to grow as not all embryos have the potential to develop. As they are growing we are able to select the best quality for replacement.
Cryopreservation of embryos offers us several possibilities:
- The storage of surplus embryos of good quality
- Postponing embryo transfer is special cases like poor endometrium, or severe OHSS.
- The preservation of reproductive potential of a woman prior to chemotherapy, radiotherapy or ovariectomy.
Embryo Freezing is a specialized advanced technique which involves the use of specialized media, apparatus and expertise. We at Sarthak Fertility have all these specialized devices to increase the outcome of IVF / ICSI cycles. .
The freezed embryos can be used to be transferred in subsequent cycles by giving medicines to build the endometrium and programming the transfer as FET ( Frozen embryo transfer ) cycles.
