I recently woke up one morning with an erection that was bent at the end, just before the knob. It freaked me out (Id even lost about ¾ of an inch in length, but gained in girth go figure), so I went straight to the doctor - he referred me to an urologist.
I showed the urologist some photos Id taken and he confirmed it as Peyronie's disease. He said that in severe cases (1 in 10) he would operate, but the preferred method was to take vitamin E. I take 500IU a day, (other sites have mention 200IU 3 times a day). He also said it may take 6-12 months to notice any difference/correction or it may not change at all.
Its been 2 months now and Ive noticed a very slight change, it could be my imagination, or just that Ive become accustomed to it. But hey, I can still urinate and masturbate. As for sex, well, my wife and I are not getting on that well at the moment, so I cant comment on that.
Good luck.
