Egg and sperm donors

A supportive gesture necessary for others to form their family.

In recent years, the number of treatments we perform with gametes from donors has increased. Changes in family models or the delay of maternity are some of the factors that are making many people resort to the use of donor semen and/or egg donation to fulfill their reproductive desire.

In Next Fertility we apply a rigorous system of donor selection, both of eggs and sperm, in which we have integrated all the recommendations of the main national and international scientific societies.

We work with CEIFER Biobank, one of the largest gamete banks that offers the best guarantees for treatments that require donation. This gives us the peace of mind that all our donors undergo a comprehensive series of medical, genetic and psychological tests before they are accepted into donation programs. And we have the most demanding and complete selective process.

In Spain, the donation of gametes is anonymous, that is, the recipient women and couples cannot know the identity of the donors, nor will donors be able to know who has received their gametes.

The donation itself has a completely altruistic and disinterested character.

Selection of
egg donors

The quality of eggs is an essential factor that allows us to increase success rates in egg donation treatments. That’s why donor selection is so important to us.

We choose the donor that most resembles you

When choosing the donor, the law establishes that the selection is made according to the phenotypic features of the recipient of the oocytes, such as ethnicity, skin color, hair and eyes, height, physical build… Our team will make the selection always looking for the greatest possible similarity.

Requirements for being a donor

To be able to participate in egg donation programs, you must meet basic requirements such as being between 18 and 35 years old and have good physical and mental health.

In addition, donors are subjected to numerous clinical, gynaecological, serological and genetic tests.

Selection process

The process to make the donation of eggs is as follows:

The psychologist will be responsible for an extensive evaluation through an interview and structured questionnaires. The goal is to have as much information as possible from our donor and to rule out the presence of any type of psychopathology. It is essential for us that donors have a good psychosocial adjustment.

We need to know the health status of the donor. We perform a complete gynecological examination, as well as general blood tests and serological tests to rule out infectious diseases.

To reduce the risks of transmission of hereditary diseases, we carry out a genetic screening of our donors. We studied more than 300 autosomal recessive genetic diseases linked to the X chromosome. We applied exhaustively all the recommendations of the Spanish Fertility Society (SEF), including the analysis of pathogenic variants related to cystic fibrosis mutations (CFTR), spinal muscular atrophy (SMN1), nonsyndromic sensory deafness (GJB2) and more prevalent hemoglobinopathies (HBA1/HBA2, HBB: alpha and beta thalassemia, sickle cell anemia). In addition, a molecular study of the FMR1 gene related to Fragile X syndrome is performed.

Once all the psychological, medical and genetic tests have been carried out, the donors join the donation programme and begin their treatment. The extracted oocytes shall be transferred to the laboratory and subsequently to the egg bank for use when necessary.

Selection of
sperm donors

To be able to offer the best results in treatments with donor semen, it is essential to have the guarantees of a semen bank of the highest quality. The Next Fertility family has among its members CEIFER Biobanco, one of the largest gamete banks in Spain. Our bank has one of the most demanding donor selection procedures, incorporating continuous testing for sexually transmitted diseases and genetic. In addition, all donors must meet sperm parameters above the standards and recommendations of the World Health Organization.

What will your donor look like?

We will choose the donor that most matches the phenotypic characteristics of the recipient partner and in the case of not having a male partner, the most similar to it; that is, its blood type, skin type, eye color and hair type, weight, height…

Requirements to become a donor

Sperm donors must be between 18 and 40 years old and comply with strict medical and psychological requirements.

We carry out an exhaustive medical history, reproductive history (if you have children, pregnancies or abortions in your partners), occupation, life habits… to get as much information as possible about the future donor.

Selection process

The process for performing semen donation is the following:

We need to know your history, including your family medical history, in detail to rule out hereditary diseases, etc.

It is important to check that your physical health is optimal. Donors, in addition to a general analysis, serology studies are performed to rule out infectious diseases such as Hepatitis B, C, HIV, Syphilis, Cytomegalovirus, Human Papillomavirus (HPV), and Chlamydia Trachomatis. This test is done in the first phase of the donation, and then repeated at 6 months.

If all the above requirements are met, they proceed to the second phase of the study, which is the analysis of a seminal sample that is performed in the center itself. In addition to the usual parameters of sperm quality, we subjected the semen to a bacteriological study, to rule out any pathogenic microorganism that could cause pathology in the recipient woman or failure in the processes of In Vitro Fertilization.

Infertility and/or sterility are generally spoken of interchangeably, but they are not really synonymous. Infertility is referred to as the impossibility of getting pregnant after a certain period of unprotected sexual intercourse. However, the term infertility refers to the inability to obtain gestations capable of evolving correctly (this would therefore include cases of repeated abortions, premature births…).

Once all psychological, medical and genetic tests have been performed, donors will be considered eligible and will be able to start donating.
