Frozen Spain eggs
In winter, feeling lack of fresh fruits and vegetables, we often go to the supermarket and buy frozen strawberries, raspberries and other summer delicacies. But you must admit that such dessert does not please with the palette of tastes and vitamins. The same situation is happened with frozen eggs, which are so popular in modern reproductive medicine. They do not possess necessary quality for a successful fertilization.
Spain is one of the countries where egg donation is legal. But only few Spaniards are willing to sacrifice part of their body for the sake of infertile couples. The way out in this situation is to bring frozen eggs from another country, and to make fertilization in Spain. Such embryo transfer, from one country to another, is very popular in sunny Spain. But rather important question is rising: “Is quality saved, and whether all indicators are normal after eggs thawing?”. Chairman of the American Community of Reproductive Medicine states: “Due to the fact that detailed 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 child-bearing.”
Most promising advertising convinces mankind that vitrification, ultra-fast freezing, is a modern technique which allows to keep eggs for use in the indefinite future. We are strongly persuaded to run to the clinic and freeze own eggs! Such procedure allows to plane pregnancy for the period that will be more convenient to us, at any age. Yes, it goes without saying; on the one hand, this technique is good: it allows you to save reproductive capacity of women during treatment which may affect her fertility, as well as to delay birth of a child at a later period.
Institute Marques (the world-famous center of reproductive technologies, gynecology and obstetrics in Barcelona) has a resolution of the Generalitat de Catalunya (Government, part of the Spanish state system of Constitutional Monarchy) for vitrification of oocytes. It makes Spanish women possible to take advantage of freezing and storage of eggs. But as of effectiveness of such a procedure… people do not think about it very much. Besides, in Spain, eggs are divided during the procedure of fertilization. It is important to note that frozen and in addition divided cells do not bring a guaranteed result – it is maximum 6% of successful fertilization.
Banks of eggs storage, of course, delicately down low about this fact. After all, such procedure significantly increases their fund: sum that is required for the collection and storage of materials is not small.
So is cryopreservation of eggs good or bad procedure? In this situation, it’s quite difficult to say which one of scales overbalances. As procedure of eggs freezing has both advantages and disadvantages. One of the main advantages is that saving own healthy eggs in young child-bearing age women can easily continue to build a career, make money and not afraid of any desperate disease that can lead to infertility. Woman’s age at the time of transplantation of fertilized egg does not matter, much more important is the age when cells were received and frozen.
So maybe in 10 years, international medicine and science will achieve highest level of development, and there will be an innovative method of eggs freezing as a result of which quality of material will be maximally saved. And then Spain will be able to impress the world with a high birth rate using assisted reproductive medicine techniques.
