Preserving Eggs Is Need Of This Hour


The availability of sperm freezing was in practice since 1950, but it took almost 50 years to make the process of egg freezing readily available for those women who want to preserve their fertility. In 1986 the first successful pregnancy was announced with thawed and frozen human oocytes.

Cryopreservation is one of the most exciting and interesting techniques ever discovered in the field of Assisted Reproductive Technology. This is the technique that adds an important dimension in reproductive science by:

Increasing the pregnancy possibility specifically when couples want to have another child successful transfer of embryos. Preventing many ethical dilemmas by removing the need to embryos dispose. Preventing the wastage of embryos. Extending pregnancies per cycle with 10-30% more positive outcome. Provide an alternative to those couples taking risk of multiple pregnancies by transferring more than one healthy embryo to ensure successful pregnancy.

How The Embryo Cryopreservation Works?

The process is following with In Vitro Fertilization where large number of embryos created with the help of certain fertility drugs like gonadotropin and clomid before implantation, just to assure that at the time of transfer there are enough viable embryos are available. However, to prevent the risk of multiple pregnancies, only one or two can be implanted at one time to the uterus of female. The others left healthy embryos may be cryopreserved for the future IVF cycle. The whole process involves some steps including the healthy embryos are mixed with a cryoprotectant that protects them from damage in freezing process. The mixture is place in very thin glass tube and placed in a machine filled with liquid nitrogen at very low temperature around -196 degree Celsius. When couples need that embryos, tube is removed and embryo is thawed. In this way, protective fluid is removed and then embryo is prepared for transfer process. 

Why Consider Cryopreservation? 

The world of infertility is complex in itself as so many things are there that need to be considered and lots of decision are need to be made. Here are some of the common reasons where embryo cryopreservation required to be considered:
·        For couples who want to maximize the success of live birth
·        For females who have high risk of OHSS (Ovarian Hyper Stimulation Syndrome)
·        For couples who face difficulty in fresh embryo transfer (in rare cases)
·        For those who need to undergo chemotherapy for cancer treatment

The success rate of pregnancy and live births using frozen embryos may vary to fertility Center where the procedure is carried out. When you are going to compare the success rates, consider all the factors that can influence the statistics such as female's age, cause of infertility and the number of embryos implanted. When considering the success rate of a particular clinic, keep in mind that some clinic may actually transfer more than one embryo just to ensure a successful pregnancy. In addition, every embryo cannot survive the process of cryopreservation.
