State of the ART Laboratory

The Embryology Laboratory at Assisting Nature is at the core of our IVF Clinic. Our highly trained Embryologists work to determine the best environment, technology, and equipment that meets the highest standards of excellence. They also engage in continuous monitoring and quality control to improve these standards. Their expertise and dedication to lab operations continuously produce high-quality results enabling them to achieve some of the highest live birth rates. 

  • ISO Standards
  • State of the art equipment
    • Benchtop Incubators allow continuous control and stability of all the important parameters and ensure the maintenance of the ideal conditions in an embryo culture
    • Time-Lapse incubator. A time-lapse incubator contains an intergraded video system that allows the continuous digital imaging of the embryos. In this way, embryo cultures can be assessed in a detailed and constant manner, since the fertilization day and until the time of the embryo transfer. Time-lapse incubators offer the advantage of a substantial limitation in embryo handling and condition disruption. Moreover, they offer to the embryologists new morphokinetic values of embryo assessment, to optimize the selection of embryos that can lead to pregnancy.
    • RI Witness using RFID (Radio Frequency Identification) technology to track and record patient samples at each step of the ART process works as a safeguard and a reassurance for both the clinic and the patients.
  • Log and Guard Alarm systems. Quality Control (QC) and Quality Management Systems in IVF, with a continuous monitoring and alarming system, guarantees uninterrupted optimal culture conditions for the embryos.
  • Hepa filters providing high quality filtrated air under positive pressure. 
  • Certified culture media

I highly recommend dr. Robert! He was very supportive throughout the whole process and provided me with detailed information about the procedure of egg vitrification beforehand. He was also very responsive and extremely nice to work with.

The whole process was smooth and very efficient. I arrived two days before the procedure, but prior to my arrival dr. Robert was answering all of my questions and also coordinating with my local physician to make sure I’m well prepared for the procedure.

All other staff at the Assisting Nature clinic was also extremely nice and caring.

Thank you so much, dr. Robert!

Even, after so many years of effort.  I don’t remember the time when we wouldn’t try to have a baby … And it didn’t work out … A long time … We went through most of the in vitro clinics in Poland.  With many stimulations and many attempts also on natural cycles.  Unfortunately unsuccessful.  It’s hard to blame the doctors who are not responsible for that …. But it is absolutely certain to me that there is one doctor who is responsible for our happiness.  For being 15 weeks pregnant with our twins.  A doctor who assists nature with professionalism and openness, conducts the most difficult conversation  graced and full of optimism . Doctor Robert Najdecki, who made the entire in vitro process a beautiful experience for me, culminating in a huge success and true happiness.  Indeed, Dr. Robert made me remember what it’s like to be happy. He gave us as much time as we needed.  He was and still is a very close with us, not only as a doctor, but rather as a best friend.  In fact, in vitro can be pleasant, calm and happy ending. Even if something goes wrong for unexplained reasons, what matters? You have the doctor and the team who guides you firstly like a humans and then like a medical staff.  Without a terrible rush and five minutes in the office – that’s what we used to hear in one of the best Warsaw clinics.  During these five minutes we were forced to learn that we should verify our plans to be parents.  No particular justification.  It’s just that not everyone has to be parents – the Head of one of the Warsaw clinics told to us.
The place that Robert and Vangelis Papanikolaou created can hardly be called a clinic (according to Polish criteria).  The name itself took me in a kind of modesty and honesty.  Assisting Nature is simply full of fantastic people.  Doctors are surrounded by great assistants who want to be there and help.  Wonderful, full of good energy, completely natural, with a sense of humor and grace.   I clearly remember a call on Sunday morning from embryologist Petrula, during my procedure.  She has been calling every day  to say how my embryos are.  I’ve never had such a nice and cheerful conversations with an embryologist before.  Without stress but with fun and full of support.  Yes you can do it but you have to find the right people.  My full of energy fertility midwife, Fay reassured, “stop panicking, we will do it perfectly” when my menstruation late before hysteroscopy, and I was in panic about my tickets to Thessaloniki. I am full of admiration and respect for this team – because they want to do it, not because they have to.  All these people are parents of my success and I really admire it.

Thank you … Thank you so much.

As You could see all the roads led me to Greece ?

Every day with him is an immense happiness, even more than I imagined! I wanted to thank you for helping us achieve this dream and for helping me to experience the happiness of being a mother.

I wish you a beautiful holiday.
