Stem Cell Treatment for Erectile Dysfunction

  • Erectile Dysfunction is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual performance.

  • Stem Cell Treatmentst aims to effect the Calcium-sensitive potassium channel and therefore help increase the flow of blood into the Corpus.

STEM CELL TREATMENT ERECTILE DYSFUNCTIONA penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. Erectile dysfunction is indicated when an erection is difficult to produce. There are various circulatory causes, including alteration of the voltage-gated potassium channel, as in arsenic poisoning from drinking water.

The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects.

Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility; this is somewhat less frequent but often can be helped. Notably in psychological impotence, there is a strong response to placebo treatment. Erectile dysfunction, tied closely as it is about ideas of physical well being, can have severe psychological consequences.

J Sex Med. 2014 Aug;11(8):1962-73 Authors: Song KM, Jin HR, Park JM, Choi MJ, Kwon MH, Kwon KD, Batbold D, Yin GN, Kim WJ, Koh GY, Ryu JK, Suh JK Abstract INTRODUCTION: Erectile dysfunction (ED) is a major complication of radical prostatectomy. Men with radical prostatectomy-induced ED respond less positively to oral phosphodiesterase-5 inhibitors. AIM: The study aims to examine whether and how stromal vascular fraction (SVF) restores erectile function in mice with cavernous nerve injury (CNI). METHODS: Twelve-week-old male C57BL/6J mice were used and the animals were distributed into five groups: sham operation group and CNI group receiving a single intracavernous injection of phosphate-buffered saline (PBS) or SVF (1 × 10(4) , 1 × 10(5) , or 3 × 10(5) cells/20 μL, respectively). SVF was isolated from epididymal adipose tissues of green fluorescence protein transgenic mice. MAIN OUTCOME MEASURES: Two weeks after injection, erectile function was measured by cavernous nerve stimulation. The penis was stained with antibodies to platelet/endothelial cell adhesion molecule-1, phosphohistone H3, and phosphorylated endothelial nitric oxide synthase (phospho-eNOS). We also performed Western blot for angiopoietin-1 (Ang-1), vascular endothelial growth factor-A, hepatocyte growth factor, phospho-eNOS, and eNOS in the corpus cavernosum tissue. RESULTS: Local delivery of SVF restored erectile function in a dose-dependent manner in CNI mice. The highest erectile response was noted at a dose of 3 × 10(5) cells, for which the response was comparable with that in the sham operation group. Local delivery of SVF significantly increased the expression of angiogenic factor proteins and induced cavernous endothelial cell proliferation and eNOS phosphorylation compared with that in the PBS-treated CNI group. SVF-induced promotion of cavernous angiogenesis and erectile function was diminished in the presence of soluble antibody to Tie2, a receptor tyrosine kinase of Ang-1. CONCLUSION: Secretion of angiogenic factors from SVF is an important mechanism by which SVF induces cavernous endothelial regeneration and restores erectile function. These findings suggest that cavernous endothelial regeneration by using SVF may represent a promising treatment strategy for radical prostatectomy-induced ED.
