Erectile dysfunction, as a common male disease, can seriously reduce the quality of life of men and their partners. With the improvement in people’s living standards, erectile dysfunction is considered an important health problem affecting men. However, existing therapeutic approaches struggle to meet the needs of all patients, so new treatment strategies need to be developed.
DISCOVER NEW THERAPY FOR ERECTILE DYSFUNCTION : Stem Cell Therapy in Erectile Dysfunction: Mechanisms, Cellular Protocol 2026
Exosomes, as a class of vesicles secreted by cells with a double-layer membrane structure, are involved in various physiological and pathological processes in the human body and have great therapeutic potential. In this article, we summarize the latest advances in exosome therapy for improving erectile function.
Over 5,000 years ago, erectile dysfunction was mentioned in ancient Egyptian writings. Until 1993, the National Institutes of Health defined the condition as the persistent or recurrent inability to achieve or maintain sufficient penile erection for successful penetration.
THE TRUE CAUSES OF ERECTILE DYSFUNCTION
It is a widespread medical problem that seriously affects men’s health, affecting 150 million men worldwide to varying degrees. Because the problem is more common in men over 40, it is expected that by 2025, there will be more than 322 million cases of erectile dysfunction worldwide.

In the past, it was often believed that mental disorders contributed significantly to the development of erectile dysfunction, but many studies have shown that organic causes account for more than 80% of cases. Cardiovascular disease, diabetes, dyslipidemia, hypogonadism, and nerve damage are independent risk factors for erectile dysfunction.
More importantly, erectile dysfunction is no longer associated only with sexual dysfunction, it can also signal potential vascular endothelial dysfunction, serving as an early indicator of cardiovascular disease.
WHAT ARE EXOSOMES:
Extracellular vesicles are membrane structures of cellular origin with a diameter of 40 to 1000 nm. Exosomes and microvesicles are two types that are released from the endosomal system or dissociated from the plasma membrane, respectively. Exosomes are nanosized particles with a diameter of approximately 40–160 nm, secreted by various cells.
Exosomes contain many components such as metabolites, proteins, lipids and nucleic acids. Exosomes are involved in various physiological and pathological processes in the human body and can be used as molecular carriers and signal carriers in intercellular communication.

Exosome biogenesis allows cells to rapidly and selectively remove proteins from the plasma membrane, facilitating procedures such as sperm-egg binding. Exosomes are associated with the process of viral infection and are involved in the induction of innate and adaptive immune responses. Research on exosomes and diseases has shown that exosomes may be involved in cardiovascular and metabolic disorders, and play a role in the pathogenesis of neurological disorders.
TYPES OF ERECTILE DYSFUNCTION AND THEIR TREATMENT WITH EXOSOMES
ERECTILE DYSFUNCTION IN TYPE 1 AND 2 DIABETES
Erectile dysfunction is considered one of the long-term complications of diabetes, which increases the risk of developing it by 2.5 times, and more than 50% of people with diabetes suffer from it. Patients with diabetes mellitus mainly exhibit hyperglycemia and insulin resistance, usually accompanied by metabolic syndrome (obesity, hypertension, dyslipidemia), hypogonadism, cardiovascular disease and neuropathy.
These manifestations and comorbidities affect androgen levels, arterial inflow, venous outflow, and nerve signaling and ultimately affect the production of reactive oxygen species, NO, cyclic guanosine monophosphate and nitric oxide synthase and the function of endothelial cells and smooth muscle cells of the corpus cavernosum during time of erection of the penis.
In clinical use, we have found that exosomes promote restoration of erectile function by increasing the ratio of maximum intracavernosal pressure to mean arterial pressure, increasing endothelial and smooth muscle content, and reducing apoptosis in cavernous endothelial cells and smooth muscle. cells Exosomes also improve erectile function by reversing fibrosis, increasing endothelial content and angiogenic activity in a dose-dependent manner. Meanwhile, exosomes also stimulated neurovascular function and suppressed levels of inflammatory factors.

ERECTILE DYSFUNCTION CAUSED BY DAMAGE TO THE CAVERNOUS NERVE
Prostate and other pelvic surgeries often damage the cavernous nerve, which originates from the main pelvic ganglion and controls relaxation and contraction, thereby regulating penile erection. Up to 80% of prostate cancer patients suffer from erectile dysfunction after radical prostatectomy.
Exosomes isolated from a patient with this form of complication clearly improved erectile function by inhibiting apoptosis four weeks after injection. They can alleviate the distortion of normal neuronal anatomy, smooth muscle atrophy, and collagen deposition that impair penile erection.
In addition, with 3 or more procedures, exosomes promote almost complete regeneration of nerves and cavernous nerves.
OTHER TYPES OF ERECTILE DYSFUNCTION
Vascular erectile dysfunction accounts for a significant proportion in adults and elderly patients, which can be caused by atherosclerosis, trauma and surgery. Erectile dysfunction caused by internal iliac artery injury, exosomes in these cases were proven to promote the differentiation of cavernous endogenous stem cells into cavernous sinus endothelial cells, while effectively reducing oxidative stress damage to the corpus cavernosum.

These results provide new insights and strategies for the clinical treatment of erectile dysfunction and severe arterial damage.Since erectile dysfunction is often observed in patients with obstructive sleep apnea, causing chronic obstructive hypoxia. Exosomes, in this case, influenced apoptosis and autophagy and ultimately improved erectile function).
Moreover, exosomes reduce fibrosis of the tunica albuginea and restore erectile function in patients with Peyronie’s disease.
