Viagra has long been used to treat impotence, but many men say it can be dangerous. "They're all saying, 'I'm going to take Viagra,' but this can be dangerous," said Dr. Irwin Goldstein, director of Urology and Sexual Medicine at Northwestern Memorial Hospital in Chicago.
The new studies, published in the Journal of Sexual Medicine, say that some men may experience a worsening of erectile dysfunction, and Viagra may help.
The study, funded by Pfizer Inc., is the first study to examine Viagra use among young men who've used the drug, as well as the effects of using it.
The study was presented at the American Urological Association annual meeting in San Antonio. The study was funded by Pfizer Inc., the maker of Viagra, and the maker of Viagra Connect. The men were randomized to one of four treatment groups: treatment with Viagra Connect for at least two years, or treatment with Viagra Connect for six months, or treatment with Viagra Connect for two years.
The researchers say that they did not know the effectiveness of the treatment groups for six months. They also do not know whether the use of Viagra may be associated with an increase in sexual desire.
In the study, the researchers examined the effect of Viagra on sexual desire. They found no significant differences between the four treatment groups in their sexual interest.
The researchers say that they are not recommending that men who have had sexual contact, including intercourse, with a man who is a man of sexual interest.
According to the study's authors, that may have led to an increase in the number of sexual encounters.
The researchers note that their study was conducted only in men with erectile dysfunction.
In addition to the new studies, Goldstein also said that he has received support from a number of organizations and individuals to speak on his views.
"We are grateful for the opportunity to be here, to help patients who are not ready to continue their treatment with Viagra," Goldstein said.
According to Goldstein, he also works with a group of patients who are looking for a more affordable alternative to Viagra.
The study was published in the Journal of Sexual Medicine.

The new Viagra 50mg tablets are expected to be sold over the counter in the US in December.
In a letter to the US Food and Drug Administration, the agency warned that Pfizer, the makers of Viagra, have been under attack from the US pharmaceutical giant. In the letter, they said that the drug had been tested on patients who had taken the drug. However, the drug’s patent, which protects the drug against side effects, had not yet been approved by the US Food and Drug Administration.
Pfizer said its patent for Viagra (sildenafil) and the other active pharmaceutical ingredients (API) was being protected by a patent that had not been given.
“Our goal is to be able to make the drug safe and effective in the US and other countries where it is already sold,” the company said in the letter.
The FDA’s warning comes amid allegations that Pfizer had failed to secure the approval of a US drug that would sell the medicine as a drug of its own. In December, the FDA had issued a warning letter on the drug’s patent.
The warning was based on information received from two companies.
