The Journal of Sexual Medicine has conducted a study on the effectiveness of Sildenafil
Sildenafil is a drug that is normally used in tablet form for the treatment of erectile dysfunction in men. Sildenafil is a PDE5 inhibitor like other treatments for erectile dysfunction.
The Journal of Sexual Medicine investigated the effectiveness and safety of Sildenafil by age in men with erectile dysfunction and found that Sildenafil is very effective in men regardless of age. An interesting fact about the research is that Sildenafil was tested with older men about 75 years of age and the result was positive (effective).
According to the Journal of Sexual Medicine, about 11,000 men of different ages have been tested for sildenafil and the results were positive. The research focused mainly on age groups younger than 65 years and 75 years old. The starting dose of Sildenafil was 50 mg 1 hour before sexual activity, followed by adjustment to 100 or 25 mg based on efficacy and safety. Placebos were also used for the test and there was also a positive result.
Overall, the conclusion was that orgasm function, satisfaction with sexual intercourse and sexual desire increased significantly in the age categories mentioned, except that there were some minor side effects in each age group, including headache and blushing.
