Double gamete donation is an in vitro fertilisation (IVF) treatment in which eggs and sperm both from donors (rigorously selected using medical protocols) are fertilised.
It is particularly recommended when patients are unable to provide or use their own gametes for medical, genetic or personal reasons.
If this is your case, this treatment offers the highest success rates and a real chance of becoming a mother/parents.

What is double donation?
Double gamete donation is an in vitro fertilisation (IVF) treatment in which both eggs and sperm used to create the embryos are from donors.
These donors are always anonymous, as established by Spanish law, and are carefully selected according to physical characteristics compatible with the recipient patient or couple.
Once the donated eggs have been obtained, they are fertilised in the laboratory using the ICSI technique. After this process, the generated embryos develop during 5-6 days in the laboratory and the best quality embryo is then transferred into the patient’s uterus, so it can implant and result in a pregnancy.
Thanks to the quality of the donated gametes and rigorous medical monitoring, this treatment has very high clinical pregnancy rates, even in women who have undergone several failed IVF attempts.
Success rates
The success rates of IVF treatment with double gamete donation depend on the individual circumstances of each patient. However, with the relevant diagnostic tests and good follow-up, the following success rates can be achieved with double donation:
- 70% after the 1st transfer
- 80% after the 2nd transfer
- 93% after the 3rd transfer
The double gamete donation process: step by step in Spain
First diagnostic visit
Let us know your availability and we will arrange everything to avoid any unnecessary stress in your daily life.
The initial medical consultation can be done online or at one of our fertility clinics. During this appointment, we will discuss the patient’s medical history, make an accurate diagnosis and determine an appropriate and individualised treatment strategy.
Selection of the egg donor
This is a key moment for our patients.
At Vida Fertility, we have the right technology to select the ideal donor for you, considering not only clinical compatibility and genetic safety aspects, but also meeting the expectations of each patient.
Our team of donor selection specialists fully understands the implications of choosing the right donor and the fears and doubts that our patients may have. That is why we work closely with the other specialists involved in your treatment to share information and assign the donor that best suits you.

Fresh cycles in egg donation. Donor/recipient synchronisation
The Vida Fertility team has over 10 years’ experience in developing synchronised egg donation cycles with patients from all over the world.
To adjust the treatment dates to your availability, we will prescribe medication that will allow the donor’s cycle to be synchronised with the patient’s cycle.
Endometrial preparation
At the start of her cycle, the patient will begin preparing her endometrium by taking oestrogen. The aim is to achieve a suitable endometrial thickness for embryo implantation.
At the same time, the donor will begin ovarian stimulation to enhance follicular growth and obtain a good number of oocytes.
Preparation of the semen sample
On the day of ovarian puncture to obtain the donated eggs, the donor’s semen sample is thawed. According to Spanish law, this sample must have been frozen for at least 6 months to ensure its safety.
Once thawed, the embryology team carefully processes it in the laboratory to select the sperm with the best motility and quality, which will be used to fertilise the eggs using the ICSI technique.
Fertilisation and embryo development
The mature oocytes obtained are fertilised in the laboratory with a donor’s semen to obtain embryos. As a general rule, fertilisation is performed using the ICSI technique of sperm microinjection to increase fertilisation rates. However, conventional IVF can also be used.
The embryos obtained are left under observation in the laboratory incubators until they reach the blastocyst stage (day 5 or 6 of embryonic development).
Embryo transfer
Embryo transfer is preferably performed on day 5 of embryo development, thus increasing implantation rates. It is a simple procedure that consists of placing the selected embryo in the patient’s uterus without the need for any type of anaesthesia. Embryo selection follows very strict quality criteria with the aim of achieving pregnancy in as few attempts as possible.
Who is double gamete donation suitable for?
Double gamete donation is a recommended option when it is not possible to use either the patient’s own eggs or sperm in an in vitro fertilisation treatment. It is indicated in very specific medical and personal situations, such as:
- Single women or couples of women who wish to start a family with donor gametes. This treatment is ideal for single parents or couples of women seeking the highest success rates from the first attempt.
- Cases of poor egg and sperm quality, such as in situations of azoospermia (absence of sperm), severe sperm abnormalities (oligoasthenozoospermia), very high sperm DNA fragmentation test, premature ovarian failure or menopause, whether natural or induced by treatments such as surgery, chemotherapy or radiotherapy.
- When there have been repeated failures in previous IVF treatments, either due to low ovarian response or repeated embryo implantation failures with no apparent cause.
- Presence of genetic or chromosomal abnormalities in one or both partners that cannot be resolved through preimplantation genetic diagnosis (PGT-A). In these cases, resorting to donor gametes ensures greater safety for the future baby.

Real life experiences with IVF treatments in Spain
Because we know that IVF treatment is difficult to undertake, we would like to share with you the stories of women who have become pregnant thanks to IVF with Vida Fertility.
It is incredible how, from absolute resignation, these doctors have lifted my spirits. They got me pregnant and gave me my life back. They live up to their name.
I had to find a way to become a mother if I wanted to pursue my career and not settle for just any partner. I made the right choice.
From the very first moment I felt I was being listened to, understood, and above all, I felt that my treatment was finally going in the right direction.
Hello dear Mrs Ortega,
you and the whole team of Vida fertility make us so happy. Finally a relief that we can be helped! Many thanks to you and all the others for the great care and exceptional quality work. This high quality means a lot to us. We hope that in 2024 we can take a healthy baby full of love into our arms.❤️
Thanks to Dr. Kathi’s support and by following all her advice, the best moment of the treatment came: I got pregnant.
I didn’t know if I would ever be able to get pregnant and now I’m in my 5th month of pregnancy.
It hasn’t been an easy journey. After the second attempt, I am happy to say that in two months I will be meeting my little girl.
Being able to experience this shared motherhood has been a gift for the two of us.
THANK YOU to this great team for everything!
We highly recommend Vida Fertility to anyone who has already given up hope and wants to give it one last try.
A huge thank you to the entire Vida Fertility team, especially to Sophie and Dr. Spies, who helped us achieve the wonderful project of expanding our family. We met a very competent team who perfectly guided and advised us on the medical choices to make at each stage of our journey. 🫶
I recommend Vida Fertility for their professionalism, humanism, and availability.
Our wonderful baby is the proof that the results are there!
Thank you!
Thanks to Vida fertility, we are now mums. Mums!!
It’s the greatest gift of all, we’re so happy!
The good feeling will certainly have contributed to the success of the treatment.
When we first contacted the clinic, I didn’t expect to become a mum so quickly, and now I even have hope that we might be able to create a sibling for our son with the remaining blastocysts.
Thank you!
I chose Vida Fertility because it’s a clinic that offers human support from the very beginning. I’m convinced that my state of mind, so influenced by the unconditional support they gave me, was key to the success of my treatment.
At the first consultation, I felt heard, understood, and full of hope again. The final transfer, our last chance, took place in February 2024… and it worked. Our little girl has brought immense joy to our whole family.
Being a single parent brings challenges, but I’d recommend anyone thinking about it to go for it. Vida Fertility made my dream come true with my first IVF.

FAQ about double donation in Spain
Is double donation legal in Spain?
Yes. Double gamete donation is fully permitted and regulated in Spain by Law 14/2006 on assisted human reproduction techniques. This legislation guarantees the safety of the process, the anonymity of donors and the rights of people born through these techniques.
Furthermore, Spain is one of the most sought-after countries for gamete donation by:
- Single women who wish to become mothers by choice
- Heterosexual couples
- Treatment for female couples
- People with complex genetic histories
Can I find out the identity of the donors?
No. In Spain, egg and sperm donation is completely anonymous. This means that patients cannot know the identity of donors, nor vice versa.
As specialists, we guarantee that each donor has undergone rigorous medical, genetic and psychological screening to offer our patients complete peace of mind.
How are donors selected? What tests do they undergo?
In Spain, donor selection is regulated by Law 14/2006 on assisted human reproduction techniques, which is very strict and ensures that the entire process is carried out according to well-defined medical, ethical and legal criteria.
At Vida Fertility, we apply a highly rigorous selection protocol. Most of our donors have an average age of 25, well below the legal limit (35), which favours oocyte quality.
All candidates* must pass:
- Psychological evaluation to ensure emotional stability and understanding of the process.
- A complete gynaecological examination, ultrasound scan, cytology and cultures.
- Blood tests, serology, karyotype and genetic carrier tests.
- BMI within the healthy range.
- Review of personal and family history.
Not all applicants become donors: only those who meet all the requirements and guarantee maximum safety for our patients and the future baby are accepted at Vida Fertility.
What does the price of the treatment include?
The price of double gamete donation treatment can vary greatly depending on the characteristics and history of the patient. At Vida Fertility, we believe that each case is different and each patient will need treatment and techniques tailored to their particular case. Therefore, if you are interested in knowing the price of IVF with double donation at our fertility clinics in Madrid or Alicante, we invite you to request an initial appointment with our specialists. At this time, you will receive a complete diagnosis and a personalised quote.
Can a single woman access double donation?
Yes. In Spain, an unmarried woman, regardless of her nationality, can access double gamete donation. This option is recommended for women who cannot use their own eggs due to age, ovarian failure, poor egg quality or early menopause, and who also do not have a male partner or wish to be single mothers by choice.
Double donation is also a viable alternative in cases of previous IVF failures, risk of genetic disease transmission, or when the ovaries are not functioning properly due to medical treatment or surgery.
Thanks to Spanish legislation on assisted reproduction, single women from any country can access this treatment with full medical and legal guarantees and high success rates thanks to the quality of the donors and the technology available in Spanish laboratories.
How long does the whole process take?
Double donation treatment at Vida Fertility generally takes 4 to 6 weeks, from the selection of donors to embryo transfer.
The total time may vary depending on the synchronisation of menstrual cycles and how the uterus of the woman receiving treatment is prepared.
If I am a foreigner, can I travel only once or do I have to go several times?
Many of our patients come from other countries, so we design treatments to minimise the number of visits required.
In most cases, only one in-person visit is necessary for the embryo transfer. The rest of the process (preliminary studies, donor selection, cycle coordination) can be managed remotely with continuous support from our medical and patient care team.
What is the success rate of double donation with IVF?
The success rates of in vitro fertilisation (IVF) vary depending on the individual characteristics of each patient, usually ranging between 40% and 60% per cycle.
These percentages may vary based on factors such as the patient’s age and the cause of infertility.
Who will take care of me during my treatment?
At Vida Fertility, we believe that consistency and trust are key to getting the best results. That’s why your treatment will always be monitored by the same doctor, from your first visit to the end of the first trimester of your pregnancy.
Your specialist will have a full understanding of your history, your tests results and every detail of your treatment, allowing us to offer you fully personalised and comprehensive medical care.
Only in exceptional cases – for circumstances beyond the clinic’s control – might another member of the medical team attend to you, always with the same professionalism and under the supervision of your regular doctor.
Up to what age can fertility treatment be performed in Spain?
Although Law 14/1006 on Assisted Human Reproduction in Spain does not establish a maximum age for fertility treatments, age is a decisive factor due to the increased risks for the mother and baby.
For women, the generally accepted age for procedures such as IVF in specialised private clinics is up to 50 years old, although this may differ depending on the quality of the patients’ gametes, the regulations of each country and the guidelines of each clinic.
In men, although the ability to procreate is not severely limited by age, sperm quality tends to decline over time.
It is essential to assess each situation individually, taking into account the patient’s overall health, the quality of the eggs or sperm, and other risk factors.
