What is the freezing of ovaries or cryopreservation?
The freezing of ovaries or cryopreservation is an experimental practice which involves removing the reproductive organ of the woman, to select the fragments of immature eggs that will be frozen until the patient after passing through a treatment for cancer, to decide on their relocation.
Some years ago, to women who were subjected to a cancer treatment, they wiped out the dream of being mothers, because the product of the chemotherapy they lost the ability to hormonal and reproductive. But now, the patients who overcome cancer, they can return to being mothers, thanks to the freezing of ovaries, that is to say, to preserve ovarian tissue.
The treatments of radiotherapy and chemotherapy often damage and even kill the germ cells in the ovary, which are responsible for the formation of eggs. Dr. Enrique Oyarzún, explains: “If damage occurs in these cells, the effects of the chemo and radio therapies, they die without the possibility of reproduction, and there is no more to fulfill the function of hormone production and reproductive”.
The freezing of ovaries, it is an innovative technique that consists in extracting laparoscopically -minimally invasive surgery performed with the aid of a video camera placed in the abdomen - ovarian tissue is healthy, which is subjected to biopsy to rule out the presence of cancer cells.
The pieces of tissue are frozen in liquid nitrogen, and wait about five years after the end of treatment against the cancer for reimplantarlos in the patient, also laparoscopically.

However, there are girls who manage to menstruate, and in such a case, the ovarian tissue frozen can be used to replenish the fertility when it has been lost”.
