A Prospective Comparative Study of Autologous Bone Marrow-Derived and Adipose Tissue-Derived Mesenchymal Stem Cells Versus Platelet-Rich Plasma and Standard Therapy in Patients With Organic Erectile Dysfunction

Erectile dysfunction (ED) is a common condition characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual activity. It can significantly affect physical health, emotional well-being, and quality of life for both patients and their partners. Standard treatment options include medications such as phosphodiesterase type 5 inhibitors, vacuum devices, intracavernosal or transurethral therapies, and surgical implantation of penile prostheses. In recent years, low-intensity shock wave therapy has also been introduced as a treatment option. However, these approaches may have limitations in effectiveness, invasiveness, or long-term outcomes, highlighting the need for alternative therapies. Advances in regenerative medicine have introduced new potential treatment strategies, including the use of autologous mesenchymal stem cells derived from bone marrow or adipose tissue. These therapies aim to improve tissue repair and restore erectile function. Previous preclinical and clinical studies suggest that mesenchymal stem cell therapy may be safe and effective, but direct comparisons between different sources of stem cells remain limited. This prospective study aims to evaluate and compare the safety and effectiveness of autologous bone marrow-derived mesenchymal stem cells, adipose tissue-derived mesenchymal stromal cells, and platelet-rich plasma (PRP) therapy in patients with organic erectile dysfunction. A control group receiving standard conservative treatment, including low-intensity shock wave therapy, will also be included. The study will be conducted in a population of patients in Kazakhstan and will assess outcomes before and after treatment to determine improvements in erectile function and overall patient well-being. The results may help identify more effective and regenerative treatment approaches for patients with organic erectile dysfunction.
