Frozen eggs of Spain for the IVF

More and more women hurry to freeze their eggs to delay pregnancy for a more appropriate period. Oocyte cryopreservation technology is very popular today all over the world in particular in Spain. Spain frequently use frozen eggs in reproductive medicine, in particular during the IVF programs. As not many Spain citizens agree to donate part of their body for the sake of some infertile couples, private clinics buy these eggs and transfer them from other countries to Spain.

All fine and dandy but in practice, cryopreservation of oocytes has both its pros and significant cons. On the one hand such method is great chance, for example, for patients with cancer diseases. Because freezing cells in a healthy state, you can not be afraid of diseases that can affect the process of conceiving and carrying a child. And when it comes to late pregnancy, in this case frozen oocytes can seriously quit on. The matter is doubtful quality of frozen material and as a result it can cause unsuccessful pregnancy.

Spain is a modern developed European country. Medicine of this sunny state is considered to be one of the best in the world. So why, for example, Ukraine, country of the third world, breaks all possible records as of successful IVF and surrogacy programs realization??? Comparing Spain and Ukraine in general and medicine in particular, it is as one of the first mobile phones and the latest model of iPhone. Ukrainian clinics attract women from across the country with bright advertisements, so that they become egg donors and surrogate mothers. These women are paid "a penny" for such serious programs, and consequences of such procedures as egg donation, is far from bloomy. Thus, in the case of wrong dosage of hormones (donors take them to produce more eggs) it can be an ovarian hyperstimulation syndrome, which can even cause death. As a result of hormonal stimulation, donor can face a whole bunch of diseases and complications. But donors agree to participate in programs, doctors stimulate, while Ukraine is in the list of leaders in the successful implementation of IVF and surrogacy programs. In the Internet one can find a lot of articles about the fact that Ukrainian doctors work wonders in the field of reproductive medicine! And foreign infertile couples travel to Ukraine from all over the world, fighting with their own fears to find themselves in a wild country, in the hands of uneducated doctors who work in conditions of the last century. But what is the secret of their great success?

After meeting with representatives of Ukrainian clinics of reproductive medicine, as well as studying various medical forums, the answer has appeared itself. Work with fresh eggs is the core of success of in vitro fertilization programs. Combining fresh eggs with sperm and performing embryo transfer on the fifth day (the most successful period to work with blastocysts) Ukrainian specialists (Europeans call them Neanderthal man) achieve fantastic results.  

Female germ cells are large and contain water. So after their cooling (in particular, freezing) crystals are formed, which distort the integrity of the gametes. As a result, due to cell homeostasis disturbance, most part of material can not be used for fertilization. Also, there may be defects in cells, not visible during transplantation. Such degeneration of the genetic material in the future, can significantly affect the health condition of unborn children.

Chairman of American community of Reproductive Medicine states: "Although analysis of literature shows that cryopreservation technique is effective for women who need it for medical reasons, we can not use it widely to plan births."

Today, Spain activates vitrification method (modern method of ultra-rapid freezing of genetic material). Vitrification can enhance quality of freezing - thawing oocytes process; as a result material is exposed to less risk and has more chances to survive. But, anyway, this is far from ideal. Freezing of mature eggs is still a new science, and scientists continue to work on improving this technology. There are many issues that are needed to be done to optimize the processes of freezing and thawing eggs. So maybe in 10 years, the world of medicine and science will achieve great results and develop freezing technology, it will be an innovative method of egg freezing as a result of which the quality of the material will raise and number of miscarriages, ectopic pregnancies and congenital anomalies will be minimized. And then Spain will be able to boast of a high birth rate with the use IVF procedures with eggs donation and lead the list of leaders in this area.
