So 5% of people under the age of 30 had erectile dysfunction maybe like 20 30 years ago. That number has climbed to like 20%. And a lot of that erectile dysfunction, if you define what erectile dysfunction is, it is inability to maintain an erection through the completion of the sexual act. So it's not that a lot of people think that this means they can't get hard. It's not that they can't get it hard. They can get an erection. It's just they can't achieve orgasm or climax.
