April 10, 2000 (Mill Valley, Calif.) -- In his early 40s, Ron Hanson was too young to be having trouble getting and sustaining erections. But like many men, he was too embarrassed at first to talk about the problem. Hanson (not his real name) waited seven years to see a urologist. By the time he spoke up, erectile dysfunction had become a household word, thanks to the popularity of the drug Viagra. But the widely touted drug, Hanson soon learned, doesn't work for everyone. When Viagra (sildenafil) hit the market in 1998, some men thought it was the long-awaited answer to their problems. According to the Grey Clinic in Indianapolis, which specializes in erectile dysfunction, 17% of men between 18 and 55 experience occasional impotence, while 6% have regular erectile difficulties. For men over 55, that number jumps to about one in three. buy viagra in oslo If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.
