Embryo cryopreservation (the process of freezing, storage and thawing embryos) is undertaken at our centre. Freezing programme is not only mandatory as per our ICMR guidelines but also a boon for us . As the extra embryos are utilized in subsequent cycles if the index cycle fails Apart from that this process will come handy in
1.If the response for the injections is too good to proceed i.e if there is a suspicion of OHSS (hyperstimulation)Embryo are frozen
2 if the uterine lining is not optimal and chance of improper implantation in on cards freezing may be considered
3 Extremely difficult embryo transfer.
Embryos are placed into straws containing cryoprotectant solutions. The freezing is undertaken with the help of Biotronics Embryo freezer, a state of art equipment which is programmed to do slow cooling. Once it is achieved embryos are plunged into liquid Nitrogen (-196 C). here the embryos are kept in goblets till we wish to thaw them.
