What Our Clients Say
“…because you made us feel almost ‘at home’, you always welcomed us and treated us with such kindness…”
“…they are simply the right people in the right place, doing their job from the heart…”
“…The doctor provided us with great support…”
"First of all, we would like to thank all the staff at the SPLN center for their dedicated work, thanks to which we became a family after many years of waiting.
Katarína and Klaudia guided us by the hand from the very beginning, kept our hopes alive, and were an immense support to us in every way, for which we will be forever grateful.
We would also like to thank Dr. Lazar, who made us feel completely safe during consultations, examinations, and procedures, and always had an encouraging word or a witty remark for us 😊.
We highly recommend SPLN to everyone; choosing the SPLN team was the best decision we could have made! Secondly, we would like to thank you for the unexpected gift you sent for our baby—it is a noble gesture and a wonderful initiative. ♥️🙏"
"Thank you for your hard work, for all the help and support. Especially to the two coordinators. We are immensely grateful to the entire staff at the clinic! To all of you, because you made us feel almost 'at home,' always welcoming us and treating us with such kindness. On our 4th attempt, after a long year of struggling, I managed to get pregnant, and after a difficult journey (bleeding, GDM, lifethreatening triglyceride levels), our little miracle Benett was born on February 26, 2025, at 36 weeks + 3 days of pregnancy—a healthy and ultra-cute little guy. I wish you all perseverance in your daily work and continued success in your endeavors. Thank you."
"Hello everyone, I am 44 years old, after my second transfer (FET), and currently in the 12th week of pregnancy with twins. Dr. Lazar, Klaudia, and Katarína are all very welcoming, supported us, and helped us ... they are simply the right people in the right place, doing their job from the heart. I can highly recommend Sanatorium SPLN to all patients who long for a baby. Thank you!"
"The atmosphere there is great. During our first visit, everything was so new, unfamiliar, full of people... but by our second visit (meaning the 2nd IVF cycle), we went in already knowing what to expect. We were more relaxed. The staff, the rooms, the doctors... we can't say a bad word. Everything was great. I didn't even feel like I was at a doctor's office. A waiting room with comfortable seating, a TV, kind and smiling nurses. And the doctor? He is a fantastic, positive person with a compassionate approach and a great sense of humor..."
"My husband and I had been trying for a baby, but as we were unsuccessful for a long time, we decided to seek professional help and visited the SPLN sanatorium based on a recommendation from friends.We were very satisfied with the environment, the staff, but above all with Dr. Igor Lazar. He is a very pleasant, compassionate person and, most importantly, a great specialist. He explained everything to us in detail, prepared us for what was ahead, and even warned us that it would be a challenging period, but the result would be worth it. The doctor provided us with great support, constantly gave us advice, and had no problem answering the phone even outside of working hours, guiding us through seemingly minor issues that were 'huge' to us at the time. He was right—I am now in my fourth month of pregnancy and it is an indescribable feeling for us. My husband and I are enjoying this time together and looking forward to the arrival of our baby
Thank you very much to Dr. Igor Lazar and the entire team at the SPLN sanatorium. 🙂"
"Thank you once again to the entire staff for all the care at SPLN, and for helping us bring our bundle of joy home. We wish all your other patients that their dream of having a baby comes true."💖🥰🤱👼🏻
"
"More than all the methods in the world, what personally helped me the most was his composure, a bit of humor, and a positive attitude. The hormonal stimulation went smoothly, as did the egg retrieval. Our Natálka was born, and with the very first labor pains, I remembered Dr. Poláček asking me with a smile how I was going to give birth if I was afraid of giving myself an injection…"
"Our doctor was Dr. Hredzák, who explained everything to us very simply and concisely. Luckily, my husband only had to visit once—they froze his sperm, and he didn't need to go back. He used to wait for me in the car in the parking lot; I think he took it harder than I did. We only had 3 embryos, and it worked on the very first try. Our son Kubko was born, and he will soon be 13 years old..."
"Thank you, Katarína! By the way, there is a lot of useful information on the website! That is also a huge help! We are very grateful, don't be afraid of anything, go see them! I am in my 7th month of pregnancy with a little footballer in my belly! He will definitely be one, given how much he moves around already! Thanks for everything!"
"Hello, we visited you last year and we would like to thank you very much for your wonderful and professional approach. You made our dream come true!"
"We are now starting the process at SPLN in Košice. We have already undergone treatment twice in Debrecen without success. We went through a lot of examinations (gynecology, immunology, urology, as well as genetic testing). During the latest tests, they found an issue. (I already have a healthy 15- year-old son). In our case, the embryos are going for genetic testing. Ask for a list of basic examinations and go to SPLN for a consultation. The doctors are fantastic, they will explain everything to you, and a coordinator will be with you every step of the way."

















Your journey toward parenthood begins, and we will guide you through every twist and turn along the way.

Non-Binding Consultation with a Specialist
Our coordinators will be happy to answer your questions, advise you on the next steps, let you know what to bring with you, and help you schedule an appointment with a doctor right away. It is important for both partners to attend the initial consultation. Don’t delay the issue—reach out to experts and ask away. We are here for you.
What to Expect?
- Initial Consultation: Medical history of the couple, swabs, blood tests, ultrasound (USG), and a semen analysis.
- The female partner will undergo an ultrasound examination, while a semen analysis is required for the male partner (3 days of sexual abstinence is required beforehand).
- Please bring the results of any previous medical examinations and procedures with you.
- You will have the opportunity to consult with an IVF specialist (gynecologist) and embryologists.
- We will evaluate the results and agree on a personalized treatment plan or recommend further testing to determine the next steps:
IVF with Own Eggs
- Ultrasound-monitored ovarian stimulation
- Egg retrieval under short-term anesthesia
- Egg fertilization with partner’s sperm (ICSI)
- 5-day embryo culture followed by embryo transfer
IVF with Donor Eggs
- Donor egg retrieval
- Fertilization with partner’s sperm (ICSI)
- 5-day embryo culture followed by embryo transfer
IVF with Donor Embryos
- Selection of a suitable donor embryo
- Hormonal preparation of the recipient
- Embryo transfer around days 18–21 of the cycle
Donor Program
As part of our infertility treatment services, our clinic provides clients with comprehensive care, of which the donor program is an integral part. Its goal is to provide donated gametes (eggs and sperm) to couples who do not have their own—couples who, without donation, would never be able to have a child. We maintain an extensive and accessible database of sperm, oocyte, and embryo donors, allowing us to initiate treatment for applicants without lengthy waiting periods. Would you like to help infertile couples? How to become a donor?
Causes of Infertility
Approximately 2% to 10% of couples are unable to conceive a child naturally, and another 10% to 25% are unable to conceive subsequent children.
Infertility Diagnostics
The purpose of these examinations is to identify the cause of infertility and subsequently select an appropriate treatment. Both partners are always examined.
Infertility Treatment
The appropriate treatment plan is determined based on the results of a detailed medical history and diagnostic evaluation of the couple
