Testing of viagra efficiency – the re-searches have been conducted.

In order to test the efficiency and safe action of the medicine, the re-searches have been conducted. Their total number amounted to 21. All they were of a double and random character. There was a control group within each research which got a bread pill. Nearly three thousand subjects have agreed to participate in these experiments. The conducting of it lasted during half a year. All patients belonged to different age bracket: the youngest was nineteen, the oldest was eighty-seven years old. They all had the erectile dysfunction which progressed out of different reasons. The global problem was assessed, and also the efficiency of medication was thoroughly investigated. Every related data was registered to the special log, where the questionnaires filled by their partners were kept.

The efficiency of sildenafil was defined according to different criteria. The researchers put special attention to whether the erection occurred, the duration time of erection and realization of a normal sexual intercourse. After all, the efficiency of the medication was clearly established, which was proven by numerous investigations conducted within a long period.

The group of researches was also curious about which dosage should be the most favorable for getting a desirable result. In the course of experiment conduction, the investigators found that for 62 per cent of the patients 25 mg of sildenafil was quite a sufficient dosage. When taking 50 mg of this medicine, at the amount of satisfied patients increased up to 74 per cent. The highest rate was observed in the case of taking 100 mg of sildenafil – 82 per cent of testes declared a positive result. However, only 25 per cent of those who used bread pills had an improved erection. In addition to all this, it was revealed that taking viagra not only treats erectile dysfunction but it also contributes to erection stability. Moreover, the pleasure from sex increased significantly, and the orgasm became more “explosive”.

Besides, patients with different pathologies were investigated as well. Sildenafil proved to be a healing medicine, since 59 per cent of diabetics got a more stable erection. Those with spinal cord traumas could realize a normal sexual act, and their percentage amounted to 83%. They all felt the significant improvement of their intimate life. 43 per cent of patients who had radical prostatectomy also noticed the improvement of their genital functions after taking sildenafil. Still, people who took bread pills showed lower indicators – 16 per cent, 12 per cent, and 15 per cent respectively.

It is interesting to note that those who took viagra and those men from the control group who took bread pills, had an equal amount of sex transactions – nearly twice a week. However, patients who took viagra were much more successful – they showed a positive result in 66 per cent of cases, while men from the control group showed only 20 per cent.

It was also revealed that viagra influenced mostly those patients who had been taking it for a long time. 88 per cent of men who participated in the longest research, which lasted a year, had an increased erection
