Viagra (Corbis)

Well, that really depends on whether or not you truly have a problem getting an erection. But you don’t necessarily need a physical health issue in order to benefit from at least short-term use of a drug like Viagra.

“Adrenaline is the post powerful anti-erectile substance out there,” says urologist Tobias Kohler. “So if you’re worried or anxious about getting erections, that stress causes you to produce more adrenaline, and you won’t get an erection.”

Dr. Kohler says in those circumstances he will often give guys (mostly young, healthy ones with no medical reason for having difficulty with erections) a couple weeks of ED medication just to help them get their confidence back.

Dr. Kohler does warn against falling for any of the TV or online ads for so-called sexual enhancement formulas. “They’re either complete garbage or actually unsafe,” he says. If you need help in this department, better to ask your doctor for something that’s been proven to be both safe and effective.

Tobias Kohler, MD, MPH, is a urologist and an associate professor at Southern Illinois University School of Medicine.
