What Does “Success Rate” Really Mean in Medicine?
In a medical context, “success rate” refers to the percentage of patients achieving desirable goals, such as symptom reduction, disease remission, or improved quality of life.
For stem cell therapy, success rate might mean reduced joint pain, restored mobility, or halted disease progression. However, metrics vary by condition, making direct comparisons challenging.
How Doctors Measure Stem Cell Therapy Success
Clinicians assess higher stem cell therapy success rate through patient-reported outcomes, imaging results, biomarkers, and long-term follow-ups. By combining clinical data, patient feedback, and advanced diagnostics, doctors can get a clearer picture of the success rate of stem cell transplants, helping guide safer and more effective treatments.
Key Methods for Measuring Stem Cell Therapy Success Rate
| Patient-reported outcomes | • Pain reduction (e.g., using pain scales) • Improved quality of life • Better daily functioning |
| Imaging results | MRI or X-rays can show: • Tissue regeneration • Reduction in inflammation • Improved joint or bone structure |
| Biomarkers | Blood tests or tissue samples may reveal: • Decreased inflammation markers • Enhanced cell regeneration indicators |
| Long-term follow-up | Monitoring patients over months or years helps determine the durability of results and overall treatment effectiveness. Short-term improvements are encouraging, but long-term follow-ups are essential to: • Ensure sustained benefits • Track any delayed side effects • Refine treatment protocols for future patients |
The Latest Safety Studies: What Is the Success Rate of Stem Cell Therapy
As with any evidence-based science, building a strong foundation takes time. Over the past decade, a growing number of studies have demonstrated the safety and effectiveness of stem cell treatments, particularly highlighting the advantages of mesenchymal stem cells (MSCs).
For example, a review of 62 clinical trials involving more than 3,500 patients found that MSC treatment is generally safe. Most reported side effects—such as mild fever, fatigue, or difficulty sleeping—were temporary and not severe. Importantly, no serious adverse events were observed across the studies.
Stem Cell Therapy: Success Rates Across Conditions
Reproductive health, neurological disorders, and orthopedic issues are just a few of the many conditions that have shown improvement after stem cell treatment. But how effective is stem cell therapy in reality? The answer depends on the condition being treated. Let’s explore what the latest research reveals.
Neurological Disorders: Success rate of stem cell therapy for Parkinson’s disease
For neurological conditions like Parkinson’s disease, early studies suggest improvements in motor symptoms such as walking, speaking, and facial expressions. Stem cell therapy for Parkinson’s disease demonstrates a range of strong results:
- A group of 53 patients showed a safe and positive response to stem cell treatments from bone marrow or adipose tissue.
- In another case, 4 out of 5 patients maintained stable symptoms after therapy.
- 20 Parkinson’s patients reported better scores in areas like cognitive function, mood, and speech.
Orthopedic Conditions
The success rates of stem cell therapy for knees are among the highest in the treatment of joint and bone conditions, with studies showing a 70–80% improvement in pain reduction and joint function.
- In a study of 329 people with knee problems, most avoided knee replacement surgery for at least two years.
- Among those with severe issues, 63 out of 70 were able to maintain an active lifestyle without surgery.
Though some patients experienced temporary swelling or discomfort, the treatment was generally regarded as safe and effective when compared to traditional methods.
Autoimmune Diseases
For conditions like multiple sclerosis (MS), stem cell therapy has shown potential in helping to “reset” the immune system, with growing interest in the stem cell transplant for MS success rate as studies continue to report encouraging outcomes in reducing disease activity and slowing progression.
- A study involving 24 people with progressive MS, unresponsive to standard treatments, found that 22 of them stabilized or improved over four years.
- The therapy appeared to reduce hidden brain inflammation and even start repairing nerve coverings—all without serious side effects.
Reproductive System Diseases
Stem cell therapy is also showing early potential in treating reproductive system diseases and infertility.
Peyronie’s Disease (PD)
A 2017 study using adipose-derived stem cells (ADSCs) showed improvements in penile curvature, plaque size, and erectile function. These stem cells are widely used due to their easy extraction and regenerative properties. Multiple studies suggest ADSCs may help prevent or treat fibrotic diseases like PD.
Fertility Support
Recent research highlights the potential of various types of mesenchymal stem cells (MSCs)—including umbilical cord-derived (UC-MSCs) and bone marrow-derived (BM-MSCs)—in treating female infertility:
- UC-MSCs are easy to collect, safe, and effective in restoring ovarian function by reducing apoptosis and inflammation, promoting angiogenesis, and aiding endometrial repair. They have shown positive results in early human trials.
- BM-MSCs have demonstrated anti-inflammatory and regenerative effects in ovarian tissue, especially in models of PCOS and chemotherapy-induced ovarian damage.
How Effective Is Stem Cell Therapy for Erectile Dysfunction?
Clinical studies have shown that MSCs hold significant promise for treating erectile dysfunction (ED) of various causes, including diabetes, post-prostatectomy nerve injury, and vascular insufficiency. Key clinical findings:
| Adipose-derived stem cells (ADSC) | In a 2015 study, 4 out of 6 diabetic patients regained spontaneous erections within one month, with effects lasting up to a year. Another study from Denmark confirmed significant improvements in erectile function at both 6 and 12 months post-treatment, with no serious side effects. |
| Umbilical cord stem cells (UCSC) | In a trial involving diabetic men aged 57–83, most patients recovered morning erections within a month, and results lasted at least six months. A later trial confirmed safety and improved penile blood flow at 6-month follow-up. |
| Bone marrow-derived stem cells (BMSC) | A long-term study (mean follow-up of 62.1 months) showed that intracavernous injection of BMSC was safe and effective, with initial improvements in erectile function and sexual satisfaction. Although a slight decline occurred after the first year, no adverse effects were reported. |
The clinical success rate highlights the positive outcomes of stem cell therapy for erectile dysfunction:
- Up to 67% of patients in trials experienced restored erectile function.
- Sustained improvement in sexual function was observed at 6–12 months.
- No serious adverse events were reported across studies, confirming a strong safety profile.
Autism
The stem cell therapy success rate for autism is increasing with approved results. A review of 11 studies involving 461 patients reported significant improvements in areas such as social interaction, motor function, and behavioral skills. Notably, the most marked progress was observed in the “relationship to people” and “body usage” categories. Although some mild side effects like fever and hyperactivity were reported, no serious safety concerns were identified.
Mesenchymal stem cell therapy for autism spectrum disorder (ASD) showed improvements in patients’ well-being and cognitive abilities, according to research conducted by our doctors at Swiss Medica, a stem cell clinic in Serbia.
How Patient Age and Health Affect Results
The success rate of stem cell transplants can vary greatly depending on a patient’s age and overall health. While stem cells have powerful regenerative potential, individual biological factors play a major role in determining how well the body responds to treatment.
| Factor | Impact on Stem Cell Therapy |
| Younger age | Often associated with better outcomes due to stronger cell activity and faster healing. |
| Good overall health | Enhances the body’s ability to accept and integrate stem cells effectively. |
| Chronic conditions | If a patient has a range of chronic conditions, the effect of the therapy may be less pronounced. |
| Weakened immune system | May increase the risk of complications and limit regenerative response. |
At Swiss Medica in Serbia, we do not accept every patient for stem cell treatment. First, we carefully review each individual’s medical history and current health condition. Based on this evaluation, our medical advisors provide clear information about the potential outcomes—ensuring you can make a well-informed decision.

Can Stem Cell Therapy Fail? And Why It Happens
While the stem cell therapy success rate is high, it is important to note that it, like any other medical treatment, is not a guaranteed solution. Understanding the reasons behind unsuccessful outcomes helps manage expectations and improve future success rates.
Common Reasons for Stem Cell Therapy Failure
Certain individual factors may affect how well the therapy works. However, the examples below are not definite contraindications—each case should be carefully evaluated to assess the chances of success.
| Pre-existing health conditions | Poor general health and multiple comorbidities may hinder the body’s ability to respond to therapy. |
| Advanced cases | When the case is extremely advanced, the chances of success are lower—stem cell therapy isn’t a miracle cure. |
Before undergoing stem cell therapy, patients should consult with a regenerative specialist to ensure that they are suitable candidates.
Common Myths About Success Rate of Stem Cell Transplant
Along with the excitement, several myths persist—particularly about the adult stem cells success rates, or MSCs. They are often confused with other types of stem cells and are mistakenly seen either as a miracle cure or, conversely, as a highly risky treatment. Understanding the truth behind these misconceptions is essential for making informed decisions.
Myth #1: “Stem Cell Therapy Is a Cure-All”
Reality: While stem cells have shown promising results, they are not a universal solution. As previously stated, the effectiveness of stem cell treatments is determined by the patient’s condition, overall health, and pre-existing illnesses. It’s important to view stem cell therapy as a treatment option, not a guaranteed cure.
Myth #2: “Stem Cells May Worsen My Condition”
Reality: Like any medical procedure, stem cell therapy carries potential risks. These may include mild side effects such as fever, fatigue, or swelling.
Experienced clinics that follow rigorous protocols can significantly reduce these risks.
Comparing Adult Stem Cell Success Rates to Other Treatments
Stem cell therapy often outperforms traditional treatments in various areas, including orthopedics—offering faster recovery compared to surgery—and in managing autoimmune conditions.
| Condition | Stem Cell Therapy | Traditional Treatment | Comparison |
| Orthopedic | 70–80% improvement in joint pain and mobility | Surgery (e.g., knee replacement) | Stem cell therapy offers faster recovery and less invasiveness. |
| Autoimmune | Stabilization of resistant MS cases | Immunosuppressive drugs | Stem cells may help to reduce exaggerated activity of the immune system with fewer relapses. |
Long-Term Results and What We Know So Far
Most studies run for 2 to 5 years, and during that time, many patients report lasting improvements in their symptoms and overall quality of life. However, in some cases, results are limited—often due to using the wrong therapy or treatment approach. Research is ongoing, and as new, approved findings become available, we’ll be sure to share them.
The Role of Clinic Experience and Technology in Stem Cell Therapy Success Rate
The success of stem cell therapy isn’t solely dependent on the type of cells used—it also heavily relies on the clinic’s experience and the technologies they employ. Clinics that combine expertise with cutting-edge techniques tend to achieve better outcomes for their patients.

While price can reflect the quality of facilities and services, higher costs do not guarantee a higher stem cell transplant success rate in the UK, USA, or other European countries. Some clinics charge premium prices for unproven or experimental methods, making it essential for patients to do their homework before committing to treatment.
| Cost Factor | Impact on Success |
| High price for advanced facilities | Often associated with high taxes and strict regulations. These factors do not necessarily ensure more effective stem cell therapy. |
| Transparent pricing with evidence-based care | More likely to ensure reliable results and improved patient outcomes |
At Swiss Medica’s new hospital in Belgrade, stem cell treatment costs range from €7,000 to €31,000*, depending on the condition’s severity and the number of stem cells required. These prices are significantly lower than the European average, which often exceeds €50,000, and provide a cost-effective alternative for high-quality care. In comparison, treatment costs in the UK can range between £20,000 and £50,000, depending on the clinic and treatment protocol. However, stem cell transplant success rate in the UK is not higher than in other countries.
*The prices mentioned are indicative and subject to change based on individual factors, including the condition’s severity and the number of stem cells needed. Prices are valid as of January 2025
