In a field as sensitive and complex as assisted reproduction, scientific innovation is not just an asset but a must. Every small technological advance, every laboratory finding and every improvement in clinical protocols can make a big difference in results.
However, not all clinics apply innovation with the same enthusiasm or commitment as we do at Tambre. Incorporating cutting-edge technology, supporting research and relying on a specialised team to apply that knowledge are the cornerstones that lead to more effective, safe and personalised treatments. From embryo selection using artificial intelligence to ultra-fast oocyte vitrification, every advance contributes to a common goal: increasing pregnancy rates and reducing the emotional and physical strain on those seeking to start a family.
The science behind the success of assisted reproduction treatments
In assisted reproduction, success does not depend on just one factor, but rather on a combination of clinical, technological and human decisions that must be perfectly aligned. Science has proved that even the most subtle advances involve medical decisions that can have a significant impact on success rates.
Improving the quality of the embryo culture environment, applying more precise ovarian stimulation techniques or performing more comprehensive genetic diagnoses are examples of innovations that multiply the chances of obtaining high-quality viable embryos, reduce implantation failures and perform safer and more effective transfers.
Thanks to ongoing research and revision of protocols, we can now identify more accurately which embryos have the greatest potential, detect possible abnormalities before transfer and adapt the treatment to the unique characteristics of each patient. This translates into fewer failed cycles, less uncertainty for patients and more possibilities of achieving a viable pregnancy from the first try.
Cutting-edge technology at Tambre
Having cutting-edge tools makes the difference between a conventional treatment and a truly personalised, safe and effective treatment. Therefore, at Tambre we constantly invest in state-of-the-art technology, such as:
- Leading-edge incubators with time-lapse systems. These allow for ongoing and detailed monitoring of embryo development in real time without having to remove them from their optimal environment. This way, we can improve pregnancy and implantation rates, as our specialists can make informed decisions in real time, precisely and efficiently adapting treatment.
- CHLOE artificial intelligence. This technology uses advanced AI algorithms to thoroughly analyse embryo images and evaluate multiple criteria to identify the ones with the greatest implantation potential. Not only does it optimise embryo selection, but this also reduces the time needed to make critical decisions.
- We also perform advanced genetic testing such as PGT-A, which can detect chromosomal alterations in embryos before transfer, thus avoiding the transfer of embryos with hereditary diseases while improving implantation rates. This test is especially recommended when there is a history of disease in the family, or in patients with repeated miscarriages or implantation failures without a known cause.
- Our genetic matching system also guarantees maximum compatibility between patients and donors, reducing risks and increasing the safety of the treatment when using donated gametes.
- Another of our strengths is the ultra-fast oocyte and embryo vitrification, a technique for which we are a national and international benchmark. In fact, in 2025 (and in 2023) Tambre has been recognised with the award for Best Practice in Vitrification by Kitazato, the leading company in cryopreservation technology. This technique allows us to preserve gamete and embryo quality over the long term without compromising their survival rates or their future reproductive capacity.
An embryology laboratory that makes a difference
The Tambre embryology laboratory is at the heart of many of our achievements. Here, state-of-the-art technology is combined with the work of highly qualified embryologists whose years of experience and ongoing training ensure the highest standards.
All stages of the process are subject to strict quality control and traceability protocols. This not only gives our patients the certainty that their genetic material is being identified safely and accurately, but also ensures that the eggs, sperm and embryos are in optimal condition, which increases the success rates of assisted reproduction treatments. In addition, our IVF laboratory is evaluated monthly by independent organisations, which guarantees a completely safe and optimal environment for embryo development.
Even today, this type of traceability, monitoring and security system that we use at Tambre is not legally required in Spain. That is why many assisted reproduction clinics do not have a similar traceability system, with the consequent risk that this entails.
Shared science: research and collaboration
At Tambre, we do not just apply science, we also contribute actively to its development. We participate in leading national and international conferences, such as the International Conference of the European Society of Human Reproduction and Embryology (ESHRE), the most important scientific event in this field worldwide, where the Tambre team presented four scientific studies in 2025. In addition, we hold strategic alliances with prestigious Spanish and foreign universities and research centres in order to continue promoting knowledge and innovation in fertility.
Results that support innovation
Clinical results are the best reflection of the impact of innovation. The combination of advanced technology, continuous research and a highly personalised medical approach translates into some of the best success rates in the sector, both nationally and in Europe.
According to the latest data audited by an external body and recorded in the official register of the Spanish Fertility Society, our success rates for in vitro fertilisation (IVF) treatments using eggs from the patient are:
- 62% in women under 35.
- 58% between 35 and 39 years old.
- 42% in women over 39 years old.
Furthermore, in line with our commitment to safe, ethical and evidence-based reproductive medicine, at Tambre we prioritise the transfer of a single embryo, which means that our multiple pregnancy rate is less than 1%, well below the national average.
In egg donation treatments, our figures also stand out above European standards:
- 71% success rate on the first attempt.
- 75% on the second attempt.
- 91% on the third attempt.
And when preimplantation genetic testing (PGT-A) is used, treatments achieve a success rate of 81%, demonstrating the enormous value of these technologies in improving the probability of implantation and preventing hereditary genetic diseases.
These results not only endorse the effectiveness of our protocols, but also our commitment to excellence in reproductive medicine, based on science and focused on the patient.
Beyond numbers: the experience of our patients
Behind every success rate, and every failure, there is a personal story. For this reason, beyond the data, we are motivated by the human impact of our work. Every personalised treatment, every carefully selected embryo, every medical decision is designed to offer empathy, reduce uncertainty and restore hope to those who place their trust in us.
Thanks to the incorporation of tools such as artificial intelligence, ultra-fast vitrification and the most advanced genetic testing, we have managed to not only increase success rates, but to also shorten waiting times, reduce risks and offer our patients a safer and less stressful experience. As we always say, at Tambre we do not treat cases, we treat people.
The future: personalised reproductive medicine
The future of fertility lies in increasingly personalised medicine. Thanks to the development of predictive models and the use of big data, we will be able to tailor each treatment to the genetic, hormonal and clinical characteristics of each patient, increasing effectiveness and reducing risks.
At Tambre, we are already working with this vision in mind. The reproductive medicine of tomorrow begins today, with innovation, science and a steadfast commitment to excellence.
