Embryo adoption is a form of assisted reproduction that enables women or couples to achieve pregnancy using embryos donated anonymously. These embryos come from in vitro fertilisation (IVF) treatments in which, once the treatment cycle has been completed, the remaining embryos have been cryopreserved and subsequently selected voluntarily for donation.
Thanks to this act of generosity, other people can fulfil their wish to become mothers or fathers, offering a safe, effective and regulated option within assisted reproduction.
The success rate for embryo transfer is high. The probability of pregnancy per embryo transfer can be as high as 49%, and rises steadily to around 90% after the third or fourth attempt.
Embryo adoption is a treatment option for single women, heterosexual couples and female couples who wish to become mothers, subject to a prior medical assessment.
The process involves preparing the recipient woman’s uterus and then transferring the donated embryo, a simple, painless procedure similar to other assisted reproduction treatments. The medical team provides support and advice at all times to ensure a personalised and safe treatment.
Once the suitability of the treatment has been confirmed, the embryo is allocated—always anonymously—based on medical criteria such as blood compatibility and phenotypic characteristics, in accordance with current regulations.
The embryos are derived from previous in vitro fertilisation treatments, have been properly cryopreserved and meet strict medical standards.
Before the embryo transfer, the recipient woman undergoes hormone treatment with oestrogen and progesterone to prepare the endometrium and promote embryo implantation.
During this phase, ultrasound scans and medical check-ups are carried out to ensure that the uterus is in optimal condition. This preparation usually lasts between 2 and 4 weeks, depending on the individual case.
The embryo is transferred using a fine cannula, allowing it to be placed into the uterus in a simple and painless procedure. It does not require anaesthesia or sedation and is carried out on an outpatient basis.
Following the transfer, the patient can resume her normal daily routine, provided she follows the recommendations given by the medical team.
Following the transfer, there is a waiting period of approximately 10 to 14 days, during which progesterone treatment continues to support implantation.
At the end of this period, a pregnancy test is carried out, usually via a blood test for the beta-hCG hormone. If the result is positive, the first ultrasound scans are scheduled to confirm the pregnancy and begin monitoring it.
When it comes to embryo adoption, medical and emotional support is essential. At FIVMadrid, our specialist team guides and supports each patient through every stage of the treatment, providing a caring, safe and supportive environment.

Embryo adoption is a form of assisted reproduction that enables pregnancy to be achieved by transferring anonymously donated embryos, derived from other in vitro fertilisation treatments, into the uterus.
This treatment is suitable for single women wishing to become mothers, heterosexual couples and female couples, provided they have undergone a prior medical assessment confirming their suitability.
Yes. Both the donation and the receipt of embryos are carried out on a completely anonymous basis, in accordance with current Spanish legislation.
The probability of pregnancy following embryo transfer can be as high as 49%, increasing progressively with each subsequent attempt. As these are donated embryos, the recipient woman’s age does not have a decisive influence on the success of the treatment.
No. Ovarian stimulation is not required for embryo adoption, as the embryos have already been created and cryopreserved. The treatment focuses on preparing the uterus.
Embryo transfer is a simple, quick and painless procedure that does not require anaesthesia. It is similar to a routine gynaecological examination and is carried out on an outpatient basis.
The process usually takes between 3 and 5 weeks, depending on the condition of the endometrium and the transfer schedule.
Yes. After the embryo transfer, you can resume your normal daily routine, provided you follow the medical team’s advice.
If pregnancy is not achieved, the medical team will assess the available options, which may include a further embryo transfer or a review of the treatment to maximise the chances of success.
Yes. The donated embryos are obtained through regulated treatment programmes and meet strict medical and health criteria, ensuring the safety of the process.
