What is embryo adoption?

Embryo adoption entails adopting an embryo - the result of the union between an ova and a spermatozoon - which is then transferred to the adopting patient's uterus with the aim of achieving a pregnancy. The procedure gives patients the option of enjoying a pregnancy, childbirth, nursing and caring for a baby.

The embryos come from dual donation (ova and spermatozoa) or from couples who have undergone assisted reproduction treatment and who, after having had children of their own, have chosen to donate their frozen embryos and help other people to form a family.


When is embryo adoption advised?

  • When patients want a simpler reproduction treatment option.
  • When other courses of reproduction treatment have failed.


How is embryo adoption done?

The procedure involves placing one or two embryos from an embryo storage bank in the uterine cavity.

There is no waiting list for embryo adoption and, since embryos are cryopreserved, all that we need to do is prepare the receptor patient's endometrium and proceed to defrost and transfer the embryo on the same day. The treatment needed in order to prepare the mother's uterus is very simple and involves administration of some oral tablets or oestrogen patches up until transfer takes place, followed by vaginal progesterone tablets. The procedure usually only requires an ultrasound scan beforehand and this decreases both the number of necessary appointments and the cost. Hormone treatment begins when the female patient begins menstruating (this can be natural or artificial if she does not have periods) and endometrial development is controlled with an ultrasound scan so that the right time for transferring the embryos can be calculated.

We are aware of the potential emotional upheaval associated with embryo adoption treatment and, before it begins, we offer couples the option of a support appointment with a psychologist so that they can prepare themselves emotionally for the procedure at no additional cost.

The advantages of embryo adoption and embryo donation

Advanced cryopreservation techniques mean that embryos can be frozen until they are due to be transferred to the uterus. The process opens up the possibility of enjoying pregnancy, childbirth, nursing and parenting a child for women who are unable to become mothers using their own ova. This might be because of their age, due to gynaecological or hereditary disorders, low ovarian reserve, because they have had recurrent pregnancy losses, implantation failure or because other techniques have not been successful. It is also an option for women who wish to have children but do not have a partner.

There are no waiting lists and it is anonymous

Since there is no waiting list, the process is swift.  Embryo donation is the donation of good quality embryos from other couples’ assisted reproduction treatment who have themselves been successful and had children of their own, or from double gamete donation (an ovum and a spermatozoon). Donation is, by law, anonymous and every effort is made to optimise compatibility with the couple in terms of blood group, Rh and phenotype.

Safety and efficiency: over 600 illnesses ruled out

When embryos are the result of dual donation, we have the assurance and peace of mind of the rigorous procedures that all our gamete donors go through before they are accepted. They include:

  • Strict gynaecological, physical and health check-ups (a background of neurological and psychiatric disorders, endocrinology, digestive and oncological diseases, blood-related pathologies and so on in donors and donors’ families are ruled out).
  • A psychological check performed by a clinical psychologist, taking the donor’s social and psychological condition into account.
  • Genetic and infectious disease screening:
    • GCT: analysis of the 600 most common hereditary disorders.
    • Karyotype, cystic fibrosis, thalassaemia, fragile X.
    • Sexually transmitted diseases and serologies.

It is the simplest and most effective course of treatment for patients with reproduction issues

Embryo adoption is the most simple treatment option and couples generally choose it when other procedures have failed. In many cases, such as when women have pathologies including premature ovarian failure, menopause or a failure to respond to ovarian stimulation, or indeed if the male partner has fertility issues, it is the woman’s chance to have children. It is also an option for women who wish to experience motherhood alone, for lesbian couples and for people who wish to adopt whilst also enjoying the experience of pregnancy.

Simple preparation for the female partner

Treatment is personalised to suit each set of circumstances. Patient preparation is easier and less demanding than in other treatments and, in most cases, no hormone stimulation is required. It is only necessary in women who will shortly go through the menopause or who are going through it at the time of treatment. If the patient is going through the menopause, treatment begins with endometrium preparation. Oestrogen patches or oral capsules, as well as progesterone tablets for vaginal administration, are prescribed in order to prepare her body. When the endometrium is in optimum condition, the embryos are defrosted and transferred to the uterus. Standard practice involves transferring just one embryo because the success rate in our laboratories is in excess of 50%. This avoids the risks involved in multiple pregnancies.

Fewer visits, less medication, cheaper and more successful

The procedure involves fewer visits than in other courses of treatment because, on the whole, the only thing that needs to be done beforehand is an ultrasound scan. The number of necessary pharmaceutical drugs is also lower than in other types of treatment. All these advantages bring the cost down. Furthermore, results are satisfactory because the success rate is in excess of 50%.
