Oocyte cryopreservation or Egg Freezing
I may not be ready to become a mom at this time. By freezing or cryopreservation your eggs will be able to preserve that option for the future, ensuring that the ovules are of the highest quality. The best quality of ovules is between 20-30 years, after which the quality of these decreases, which can translate into problems of infertility and chromosomally abnormal embryos.
The fact of cryopreservation your ovules allow you to concentrate on other objectives without worrying that the fertile window can be closed.
Many investigations have studied the effects of ovarian stimulation and have not found negative long-term consequences. Serious treatment complications are rare, in fact most patients report some discomfort and mild fatigue.
The number of eggs that must be extracted depends on each particular situation, age and reproductive history. In general it is recommended that a minimum of 15 to 20 ovules be frozen to maximize future possibilities. In women older than 35 years it may be necessary to cryopreserve a larger number of eggs.
Cryopreservation puts the ovules in a state similar to glass known as vitrification. In this condition at -196 ºC in liquid nitrogen all the biological processes stop being possible to keep the cell in this state, without aging, for years. Cryopreservation is performed after an ovarian stimulation procedure that allows several oocytes to be extracted in a cycle.
Once the woman is ready, the eggs are thawed, fertilized and put back into the uterus to achieve pregnancy.
