Embryoadoption process


The total treatment duration is between 45 – 55 days.


1. Preparation of the recipient’s endometrium

The recipient woman must undergo hormonal treatment with estrogens, in order to prepare the uterus adequately for the implantation of the embryos. Some ultrasounds and medications will be necessary.

The process begins coinciding with the menstrual period.


2. Embryo transfer

It is a simple and painless process, which takes place between days 3 and 5 (blastocyst) of the culture and does not require sedation.

The selected embryos (no more than two) are introduced into the uterus through a fine cannula under ultrasound control. The process takes between 10 and 20 minutes.


At day 14th a pregnancy test is performed.


At FIVMadrid, the probability of achieving a pregnancy with the adoption of embryos is 49% in each cycle.
