What is it?
Fertility preservation is an assisted reproductive technique that permits the indefinite preservation of a woman’s eggs so that she can use them at the time she decides or is able to be a mother.
With the passing of time a woman’s fertility is reduced considerably. By cryopreserving oocytes during the most fertile years, we avoid these problems. An assisted reproductive treatment with quality eggs available will help achieve a pregnancy and a healthy child. Other indications for this technique include women undergoing chemotherapy and/or radiotherapy for cancer treatment. In these cases, fertility preservation may be their only alternative to becoming mothers.
Who is it recommended for?
For all women who find themselves in situations where their ovarian reserve is placed at risk.
- Hormone monitoring
In this first phase the ovaries are stimulated through hormone administration to obtain the highest number of eggs. The patient will be asked to come to the clinic for transvaginal ultrasounds so we can see the number and the size of these follicles.
- Egg Retrieval
The extraction of oocytes is done through follicular aspiration. The oocytes are extracted through an ultrasound guided needle that is introduced in the vagina. The patient is under sedation and the procedure usually lasts half an hour. After a few hours under observation in our clinic, the patient will be able to go home and continue with their normal daily activity.
- Oocyte cryopreservation
This technique consists of exposing the oocytes to a cryoprotectant and then reducing the temperature from 22 ºC initially to -196 ºC. This reduction in temperature is done quickly to avoid the formation of ice crystals that can damage cells. This permits the oocytes to be preserved indefinitely.
