What is Embryo Freezing/ Sperm Freezing/ Cryopreservation?
It is the procedure where sperms, eggs or embryos are preserved by cooling to low sub zero temperatures such as -196 degrees C. At such low temperature, any biological activity including biochemical reactions are effectively stopped. Advantages / Use of cryopreservation Embryos: This procedure gives patients the option of having excess embryos frozen, to be used in future cycles. During IVF treatment, a maximum of three embryos can be transferred to the uterus in any one cycle. As modern methods of stimulation often result in more than three eggs being collected during a cycle, there may be excess embryos available following treatment. • Reducing the risk of multiple pregnancy by transferring fewer embryos in the fresh cycle and cryopreservation of supernumerary embryos. • Increasing cumulative pregnancy rate by using cryopreserved embryos in thaw cycles. • Since cryopreservation cycles do not require ovarian stimulation and ovum pick up, the treatment is significantly cheaper. • In pa
