IVF results 2025

One of the most important aspects of our work is achieving clinical results. The way that results of infertility treatment are measured and displayed can vary from clinic to clinic. This can make it difficult for the patient to compare clinics and decide which may better suit their needs. It is important for our patients to understand their realistic chance of succeeding. 

At Next Fertility Nordic, we share our treatment results on a monthly basis and publish annual summaries on our website. The Estonian Medicines Agency and ESHRE collect annual data from fertility treatment clinics.  

Usually, the results of infertility treatment for the embryo transfer procedure are presented according to treatment category. In 2025, we performed 231 embryo transfers with a 45% clinical pregnancy rate on average. Patients who used NFN sperm donors for an IUI had a 17% clinical pregnancy rate. 

A pattern has arisen for the past 2 years for the lowest results to occur in both December and January. Perhaps patients are putting too much pressure on themselves during Christmas and the new year. 

2025 Clinical pregnancy rates  
Jan Feb Mar Apr May June July Aug  Sept Oct Nov Dec 
29% 63% 53% 53% 46% 57% 44% 38% 33% 35% 55% 29% 

It is important to distinguish what a clinic considers a ‘pregnancy’. A biochemical pregnancy is when an embryo implants and produces the hCG hormone which can be detectable on the home pregnancy test or a blood test, but the embryo stops developing shortly after.  

We focus more on clinical pregnancy results because it is an established pregnancy, where the gestational sac can be visualized on ultrasound at 6 weeks. The data is relatively easy to collect as most patients are still under the care of the IVF centre at this point. 

Some clinics are showing their data as cumulative pregnancy – which means per IVF cycle. This means if a patient had an IVF cycle with a fresh embryo transfer followed by 2 frozen embryo transfers and at the end achieved a pregnancy, the pregnancy data would be inserted as 1/1, i.e 100% but if they had 3 transfers their chance of pregnancy would actually be 1/3, i.e 33% per attempt.  

Ultimately the most important thing is the number of healthy children born. The live birth rate can sometimes be hard to follow since we can only calculate it starting from October of the next year and we need to rely on patients getting back in touch with us.  

In 2024, 105 NEXT babies were born. 

The number of multiple births is kept to a constant minimum at our clinic. This is the birth of twins or more babies. We average less than 1% chance of multiples with IVF and IUI procedures combined. corresponds to the average in the general population which is 1-1.5% (I,e patients who conceived naturally). 

Patients’ safety should be at the forefront of making decisions about stimulating more follicles for IUI and when deciding the number of embryos to transfer. 

As well as pregnancies, the lab are measuring key performance indicators. These include: fertilization rate, usable blastocyst rate, blastocyst survival rate after thaw, and successful biopsy rate. 

We analyse our lab work because if there is a change in these KPI values, it is important to start investigating what the possible reasons could be. Some factors could be based on things like construction, need to replace filters, change of equipment, change in materials used or change in protocols, change in staff members and so on. Apart from KPIs we are also analysing our environment. This includes: temperature, humidity, gas levels, positive pressure in the lab and whether there is any microbiology detection on surfaces. 

There is only one thing that is truly important in an IVF laboratory: everything!  

So ask your providing clinic whether they consider a pregnancy test, or are they assessing the pregnancy at 6 weeks. Find out if they are calculating their results per every transfer or per every IVF cycle or per every patient. It would be good to ask them to give you a specific chance based on your age and treatment plan that you are choosing.  

When choosing an IVF clinic, something that is also important to check early on, before even perhaps booking an initial consultation, is around the legislations because fertility care varies so much around the world. 

  • In Denmark the latest chance of an embryo transfer is at 45 
  • Norway does not prohibit PGT 
  • Cheq republic and Turkey do not treat same sex female couples  
  • Poland does not treat single women  
  • In Spain, the clinic chooses the donor on behalf of the patient 
  • Portugal permits use of only anonymous donors 
  • In Italy excess embryos are not permitted to be destroyed, so patients may face ethical and financial implications of indefinite storage of embryos that are no longer needed 
  • In northern America and Finland for example patients are kept awake for the pick up procedure with local anesthesia and narcotic pain relief 

Other things to keep in mind are about the clinic’s philosophies and policies. For example: 

  • Does the clinic access fresh donor eggs or strictly use frozen donor eggs for cycles? 
  • Are embryo transfers cleavage stage embryos (Day 2, 3 or 4 of development) or at the blastocyst stage? 
  • Are predominately fresh embryo transfers performed or only frozen embryo cycles (FET)? 
  • Does the clinic perform ICSI for all, or may IVF be an option? 
  • Does the clinics have high rates of ovarian hyperstimulation or OHSS which means they are typically retrieving large number of eggs and patients could suffer side effects after pick up? 
  • Is a clinic using electronic witnessing, or whether current protocols rely on manual double witnessing, or no witnessing at all? 
  • Does the lab follow any ISO guidelines or have certified individuals?  
  • What add ons does the clinic offer?  

Specific facts about our clinic: 

  • Unmarried couples, single women and same sex female couples are welcomed 
  • The maximum age limit for embryo transfer is before the patient has their 51st birthday 
  • Known, non-partner donors are now permitted to be brought to the clinic for a patient’s cycle 
  • Patients can specifically choose their Open ID sperm and egg donors  
  • We offer a Blastocyst guarantee program using donor eggs which ensures 2 blastocysts for transfer or a clinical pregnancy 
  • One donor can produce up to 6 children to Estonian mothers 
  • Embryos can be stored for 7 years from the freeze date. Following consent unwanted material can be discarded or donated. 
  • PGTA is allowed for all patients and encouraged for patients 38 + 
  • We can import or export reproductive material from EU and Non EU countries 
  • More conservative stimulation protocols to avoid multiples and OHSS  
  • Prescriptions are less costly than in other countries 
  • During pick up, patients are put to sleep via light sedation (short lasting general anaesthesia) 
  • All patients’ gametes are tracked using electronic witnessing 
  • We are following medical lab ISO 15189 accreditation 
  • PICSI, CHLOE and EmbryoGlue are available as add-ons 
  • Surrogacy is not permitted 


62% of patients thought that the CHLOE access to embryos positively affected their IVF experience and 70% would recommend the service to others.

Another key aspect of a fertility clinic is patient experience. This can be measured based on feedback. Patients feedback is extremely important to us. 

If you would like to share your experience with us it would be really lovely to hear about it as a google review

Word of mouth is another way that other patients get to hear about us. There are anonymous ways to share your story. This can be via email, filling out the clinic’s feedback form or via a verified link to our Doctify page.

It is always a pleasure when patients send a photo of their baby, and can be a full circle moment to visit with the baby. You are also welcome to give us any constructive criticism that you feel could have improved your experience with us. 

If you feel that Next Fertility Nordic clinic would be a good fit for you, we are looking forward to seeing you.
