Erectile dysfunction can also be treated with oral medications and penile implants. Oral medications like Cenforce 100 are only effective in roughly 70% of men with erectile dysfunction. Injection therapy, on the other hand, involves giving medications directly to the penis. Penile implants, despite the fact that they are unpleasant and require surgery, are only recommended when all other treatments have failed. Furthermore, the risks associated with this type of treatment are minimal.
