La Egg donation is what is called assisted reproduction technique in which eggs that have been donated are used by a woman who is not the surrogate. This procedure is mainly used to help those women who have difficulty getting pregnant due to fertility problems, either due to poor quality of their eggs or due to their non-existence.

What is egg donation?

With a egg donation treatment, a healthy and fertile woman is responsible for donating her eggs, anonymously, so that they are fertilized with sperm that may be from the partner of the recipient woman and future surrogate or from a donor. When the eggs are fertilized through in vitro fertilization (IVF), the embryos are transferred to the uterus of the surrogate mother.

When is egg donation necessary?

Egg donation is a procedure that gives the opportunity to gestate and become mothers to those women who have difficulties producing viable eggs or with a very low ovarian reserve. This can happen due to genetic reasons, being of advanced age or having undergone very aggressive medical treatments such as chemotherapy or radiotherapy.

How is egg donation done?

Egg donation consists of several very important steps that must be carried out with great care, since the success of this procedure depends on it.

Donor selection

Women who want to be egg donors must undergo a series of tests to evaluate their state of health, both physical and mental, genetic tests and an evaluation of their ovarian reserve to verify that they are suitable. Your medical history is also taken into account and finally tests are carried out to detect any type of disease that can be transferred to the fetus.

The choice of the donor for a specific treatment is carried out considering the phenotypic characteristics of the egg recipient, including her blood group. Additionally, we provide the option to perform “genetic matching” to further reduce the chances of passing genetic diseases to offspring.

Fertilization and embryo culture

The eggs obtained are fertilized in a laboratory with sperm and left in culture for a few days until the embryos have sufficient quality.

endometrial preparation

During this stage, the patient's endometrium is prepared to optimize the chances of embryo implantation. To do this, medication must be administered that contributes to the proper development of the endometrium, the layer of the uterus where the embryo will implant and the future baby will develop during its intrauterine life.

embryo transfer

It is the moment in which the embryo is transferred to the uterine cavity of the future mother. It is a simple process that is performed using a transfer cannula or catheter, using ultrasound guidance. It is completely painless and does not require hospitalization.

Without a doubt, egg donation is a very effective technique that offers the possibility of pregnancy to many women who want to conceive but suffer from fertility problems related to the quality of their eggs.
