The journey to natural IVF
We established NatuVitro to help women struggling with infertility challenges conceive in an as-close-to-natural way as possible, while utilising the most advanced technologies and science-based methods. We take the less-is-more approach, and avoid unnecessary medications, invasive procedures or aggressive hormonal medication – resulting in a healthier womb, mother and child.
After years of working with women from all over the world, we took note of their unique experiences, circumstances and success stories. We recognised that there was a better way of doing things and so we set about re-thinking conventional IVF treatments. Our new-generation range of Natural IVF Treatments are designed by pioneers in the field, including our founding doctor and fertility expert, Dr Markus Nitszchke.
Your eggs first
Conventional clinics are often quick to propose egg donation as the only option once a woman reaches a certain age. We prefer to explore a realistic alternative to egg donation and developed our highly specialised Mild IVF Treatment to help women with +Low Ovarian Reserve make use of her own eggs. The results we have achieved give new hope to even the most challenging of cases.
We respect your time, your health and your money
Our Virtual IVF Clinic gives you the option to experience a highly personalised NatuVitro IVF treatment plan in the convenience of your home country, decreasing the stress often associated with travel and therefore increasing your well-being. Any procedures that can’t be done via the online platform – such as blood tests, ultrasound scans, sperm tests, sperm freezing, etc. – can be performed by one of our many licensed partner clinics throughout Europe.
Environmentally-positive
Our support of the +Green Bioethics movement has put us onto a more sustainable path so that our planet can support the needs of present and future generations. Just as you can trust us to find the best natural solutions for you, we tread lightly on the planet too. Not only are our treatment plans more environmentally friendly, but we also eliminate unnecessary plastic, we reduce general usage, and we reuse and recycle wherever possible in our clinic and laboratory.
Our promise to you
We hear it often: fertility doctors ignore the woman and only focus on her body. We promise to take a 360° approach to your treatment. We will not just listen to you, but we will hear you. We will ask questions, get to know your journey and learn about your cycles and rhythms. And together, we will then harness this knowledge and enhance your body’s natural science to achieve our dream of you becoming a mother and growing your family. We will treat you as a partner and be with you every step of the way no matter what. That’s our promise to you.
Best in breed equipment
Achieving successful IVF results is a combination of having a trusting bond with our patients and a great team armed with the best tools in the world. And the Embryoscope Flex is just that. Considered to be the global gold standard in IVF incubators labs, the Embryoscope Flex is specifically developed with Natural Cycle and Mild Stimulation in mind, making it the perfect fit for NatuVitro. We are the first fertility clinic in Spain to have this best-of-breed incubator in our lab and we leverage its phenomenal technology in all of our natural and mild stimulation treatments, including the more traditional IVF treatments that we perform. In short, NatuVitro gives you the best of both worlds – access to the best equipment typically found in big fertility centres coupled with the personal attention of a boutique clinic.
Advantages of the Embryoscope Flex
Embryos get the best chance to succeed. Once inseminated, your embryo starts its natural growth in an incubator. The Embryoscope Flex is equipped with micro cameras that enable the biologist to monitor the development of every embryo, without disturbing or modifying the ideal temperature and protective atmosphere inside the incubator. As we know, a monitored and stable incubation greatly increases success rates.
Quality vs quantity. A key differentiator of natural treatments is that we focus on quality eggs and embryos rather than quantity. The Embryoscope Flex enables us to more easily identify the most viable embryos.
Additional layer of security. The machinery also helps us pinpoint the correct time to remove your embryo from the incubator. This means it is only transferred or vitrified once ready, which guarantees full traceability and quality control.
The memory of a lifetime. The embryo evolution can be recorded so you can see your baby’s journey, right from the very start.
Our Values
An integrated approach
We believe success rates are not achieved by science alone. Psychological and social factors all play a significant role in conception, which is why our NatuVitro team is a rare blend of best-in-class specialists who are genuinely invested in supporting you and your loved ones during your time with us.
Fair pricing
We want to free you to focus on becoming a mother, not on your bank balance. Thar’s why our treatment plans are fair, fully transparent and inclusive, without compromising on the quality of our services.
Respect and dignity
We promote human rights and human dignity. We actively foster a peaceful, just and inclusive environment in which there is zero discrimination in terms of ethnicity and cultural diversity. We welcome clients from all corners of the globe.
Unique legal environment
Spain’s favourable laws allow for unlimited blastocyst culture and embryo freezing, which is essential when it comes to achieving positive results for patients with low ovarian reserve. Please note however that we always follow and respect all applicable local laws and legislations.
Meet the team
Dr Markus Nitzschke
Natural Fertility Treatment Specialist
Our medical director Dr. Markus Nitzschke is a German specialist in gynecology and obstetrics with an additional qualification in gynecological endocrinology and reproductive medicine in Spain.
He received his specialist training at prestigious infertility clinics and university hospitals in France, Spain, Switzerland, Germany, USA and Japan.
During his further training at Inselspital in Bern in 2009 and 2010, he worked with Prof. Dr. Michael von Wolff, he played a decisive role in the development of natural cycle IVF.
After several stays abroad with leading IVF specialists including Dr. Osamu Kato in Tokyo and Dr. John Zhang in New York, Dr. Nitzschke was mainly concerned with the question of how the techniques of natural cycle IVF and minimal stimulation can be used in patients with low egg-cell reserves when classic IVF stimulation no longer promises success.
