Oocyte Cryopreservation

Cryopreservation of oocytes A recent paper entitled 'New Egg Store' for New York Times' New York Times' worried birth woman, Egg Store is a new option 'focused on newly improved cryopreservation technology for oocytes It is. Egg Freezing Technology It is becoming common for women to wait until the beginning of life to start home. Until recently, there was no program to save eggs for women to use later. Due to this trend and new development in the field of egg freezing, this article will provide background information on the technology, progress at this point, and discussion to support and oppose this approach.

Despite the favorable outcome of this approach, the use of oocyte cryopreservation to selectively preserve fertility is controversial in many countries. In the United States, as well as in the UK and Europe, cryopreservation of oocytes is still considered an experimental technique. In 2009, the American Reproductive Medicine Association (ASRM) Practice Committee stated that "cryopreservation of oocytes should be regarded as an experimental method only under the IRB-supported research program" It was.

In this case cryopreservation of the oocyte is used as a method to achieve all the blanks left by other techniques. In the past decade, the introduction of vitrification technology represents a significant advance in ART and now the results of cryopreservation of oocytes are similar to those of fresh oocytes (28 × 28 Cobo, A. et al. , Kuwayama, M., Perez, S., Ruiz, A., Pellicer, A. and Remohi, J.

The best strategy ART offers seems to be cryopreservation of oocytes. This technology is widely used and produces excellent results, but it is still considered experimental in ASRM. Removing the "experimental" label may be the first step to make cryopreservation of the oocyte more feasible and make it accessible to modern women. It is time to change the way to cryopreserve oocytes so that oocytes can be spread to more women.

By 2018 it is estimated that about 76,000 women will undergo a procedure called egg freezing, also known as oocyte cryopreservation, as a late pregnancy in life. It is one way. Preliminary testing is to determine whether cryopreservation of oocytes is feasible, but egg freezing is usually best for women 20 and 30 years old. In addition, pregnancy is not guaranteed and it is impossible to know which can be done before using frozen eggs. However, frozen eggs do not affect the possibility of naturally becoming pregnant or lowering the fertilization rate. Cost is the biggest obstacle for many women, the average cost of egg freezing in the US is 10,000 dollars, and furthermore the storage cost is 300 dollars to 500 dollars per year.
