"I think oral medications are the most consistently effective," he said. "Behavior modification is always nice and there are no side effects, but it's rarely effective, especially for men who have primary premature ejaculation."
"I think if patients have options, they're going to want to use a pill or a spray," said Smith.
In addition to its ease of use and potential effectiveness, PSD502 may offer another major benefit.
"I'm hoping that just by virtue of becoming news that some men will step forward, open up to their physicians and get treatment," said Greenfield.
That's exactly what happened when Viagra hit the market. Men realized it helped their erectile dysfunction, and now, they're speaking out about their problem, spurred on by celebrities such as former U.S. Senator Bob Dole and former Baltimore Orioles outfielder Rafael Palmeiro.
As for Kerner, he remembers when new treatments came on the market.
"I've had premature ejaculation since I was 18. I would have tried anything, and I've probably tried many things that weren't medically recommended."
Because he's been there, he wants other premature ejaculation sufferers to know that while there's no cure for the condition, there is hope.
"There is help and answers and there will be further solutions down the line," he said.
