In Vitro Fertilisation (IVF) is the assisted reproduction technique that consists of stimulating the woman’s ovaries to obtain eggs and subsequently inseminating them in the laboratory with the sperm of her partner or a sperm donor. Once the egg has been inseminated with sperm, they are left in an incubator so that the embryos develop in conditions that are as close to physiological as possible. After 3 or 5 days, the embryo with the best morpho-kinetic characteristics is selected and transferred to the mother’s uterus to achieve implantation and continue its development. The rest of the embryos generated are vitrified so they can be used in the future. The success rates of this technique vary depending on the age of the woman since, as the woman gets older, the quality of her eggs lose quality at a biological and reproductive level.
