Fertility preservation (or egg freezing)

Egg freezing is the chosen treatment when a woman wishes to preserve her fertility. It consists of performing ovarian stimulation to obtain oocytes and then vitrifying them in order to preserve them for as long as the woman wishes to postpone motherhood, maintaining the quality of the eggs they had at the time of vitrification. When the time comes to use these eggs, whether months or years later, they are devitrified and inseminated with the partner’s or donor’s sperm to carry out embryonic development and, finally, perform the embryo transfer.
