Couples where both members have fertility problems have the possibility of using embryos from a woman with physical characteristics similar to their own. This method considerably reduces the cost of treatment.
In a normal IVF treatment, several embryos from the same patient are incubated simultaneously. Of those that are most suitable, one of them is transferred to the patient and the rest are vitrified to be used in future cycles.
Once pregnancy has been achieved, the patient may decide to donate the embryos that she has not used so that other couples can use them in their own treatments.
WHAT IS IT?
In the double donation, eggs and sperm from a donor are used to form an embryo, choosing them based on the phenotypic characteristics of the recipient.
Embryos from another couple who decided to donate them after completing their assisted reproduction treatment are used for embryo adoption
Who is it for?
- Patients who want a simpler assisted reproduction treatment.
- Couples in which both members have fertility problems.
- Single women with low ovarian reserve or poor oocyte quality who cannot resort to IVF with donor semen.
- Patients suffering from repeated miscarriages or implantation failures.
- Couples that have genetic incompatibility.
HOW DOES IT WORK?
The selection of embryos is carried out taking into account the phenotypic characteristics of the recipient couple. Once chosen, the endometrial preparation of the patient is carried out using oestrogen and progesterone to assist implantation, after which the embryo is transferred to the patient’s uterus using a fine catheter. It is a simple procedure that does not require sedation.
- Who can donate an embryo?
There are a number of requirements that must be met for patients to donate their embryos to other couples. Firstly, the eggs must come from a woman under 35, in order to have high chances of pregnancy. In addition, negative serologies and normal karyotypes are required.
- What physical compatibility will the donated embryo have with me?
In the case of embryo adoption we look for compatibility of blood groups and physical characteristics with patients, however it isn’t as easy to match as accurately as with egg donation or double donation. In this type of treatment we wouldn’t be able to use Ovomatch, for example.
