Oocytes freezing

Specialty of Fertility Specialty

Freezing oocytes (immature ova ) is a technique used in assisted reproduction that serves to preserve, ie, to maintain their structures in latent form for a while. The oocytes that survive the thawing have a similar to those that have never frozen behavior. This means that their quality is not altered, and subsequently can be fertilized with sperm from the partner or from a donor in a laboratory and then implanted in the uterus of women those embryos that are developed, leading to a possible pregnancy. Oocytes therefore are not fertilized before freezing. Before starting treatment, the patient must take medication to produce a large number of ovules along two or three weeks.
