Vitrification is a method of freezing used in oocytes, embryos and spermatozoids, at very fast speed and with high concentrations of cryoprotectant.
Who is recommended for vitrification of oocytes?
Assisted Reproduction specialists indicate vitrification in patients who wish to preserve and defer their fertility for different reasons. Due to the increased probability of chromosomal abnormalities in oocytes from 35 years of age, vitrification is recommended at ages below this. This method has increased the survival rates of oocytes after thawing in recent years, reaching 97% survival rates for oocytes.
What risks does oocyte vitrification involve?
This is achieved by postponing motherhood without significantly increasing the risk of aneuploidies in offspring and even avoiding a possible low ovarian response that increases with maternal age.
The treatment used for oocyte vitrification is simple. It consists of hormonally stimulating the ovaries to obtain a multifolic response. Oocytes are obtained after ovarian puncture and aspiration and vitrified. This treatment does not involve major risks.
What kind of care should the patient have after the vitrification process?
After ovarian puncture, there may be slight discomfort that will cease within a few days and require no special care.
