It’s not the Viagra but the Pfizer that’s causing the problem.
The problem is more common than you think.
A recent study from the University of Pennsylvania’s, found that erectile dysfunction was more prevalent in men who had taken Viagra than in men who didn’t. (The study was not published in the
).For some men the erectile dysfunction is not a problem. They just have a lower blood flow and a lower ability to achieve or maintain an erection. But if it doesn’t affect their sexual health, they’ll probably have more issues, even with their erectile function.
The problem, according to the study, is not physical.
A study published in the
in May in the journalThein association with a study in the New England Journal of Medicine has found that erectile dysfunction is also common in people who have had a stroke or heart attack, the authors noted.The problem is that it’s very much a biological issue.
The study, conducted by University of Pennsylvania researchers, found that erectile dysfunction was more common in men who took Viagra.
According to the study, they found that there was a lower incidence of erectile dysfunction in men who had taken Viagra compared with men who didn’t.
“It was a relatively short period of time,” said Dr. Mark D. Miller, a urology professor at George Washington University School of Medicine.
“This suggests that the risk of erectile dysfunction may be increased when sexual activity is taken with medications that affect blood flow to the penis, such as Viagra.”
Dr. Miller said the study didn’t look at Viagra in a specific group of men, nor did it look at other drugs such as the ones that are used to treat erectile dysfunction.
“This is the first study to look at the potential impact of Viagra on men’s health,” he added.
The other study, which was funded by Pfizer, found that erectile dysfunction was more common in men who had taken Viagra compared with men who didn’t.

A group of doctors has recommended a trip to Goa for the treatment of erectile dysfunction, or ED in the US.
In an article published by the Guardian, Dr Nachumune Ona, a specialist in male sexual dysfunction, said that the US government-funded “Viagra” is the only drug that offers the same level of safety and efficacy as Viagra but is not the first.
The drug is produced by Pfizer, which makes Viagra and other similar drugs. It was approved by the US Food and Drug Administration (FDA) in November 2009.
A Pfizer spokeswoman said: “The Food and Drug Administration (FDA) has approved sildenafil (Viagra) and tadalafil (Cialis) to treat erectile dysfunction. We encourage patients to seek guidance from their doctor if they have concerns about the drug.
“Sildenafil is the active ingredient in Viagra and is generally well tolerated. Tadalafil is the active ingredient in Cialis.”
Ona also said that there were no “major safety concerns” with the drug, which has not been shown to cause serious cardiovascular events.
The US Food and Drug Administration (FDA) has approved sildenafil (Viagra) and tadalafil (Cialis) to treat erectile dysfunction, or ED in the US.
Viagra is the drug’s generic name, and tadalafil is the brand name of the drug.
Viagra has been marketed as a treatment for erectile dysfunction in the US since 1998, when the drug was approved to treat it.
However, there are concerns that the drug may cause an allergic reaction in rare cases.
Ona said that if you have a rare form of the disease, it is not possible to determine whether you’re allergic to Viagra or tadalafil.
