At six months, men who took a daily PDE5i had no SFPL loss, whereas those who did not take a PDE5i consistently had a significant mean 4.4 mm SFPL loss compared with baseline.“The present study is among the first to show preservation of SFPL in patients using daily PDE5i as compared with those patients not using regular PDE5i,” the authors wrote.
There have been reports of men having shorter penises after prostate cancer surgery for many years. This study looked at stretched flaccid penile length (SFPL) in men who were given phosphodiesterase inhibitors, like viagra, levitra, or cialis.
I have been recommending PDE5i for men for many years since the data shows that men who have good preoperative sexual function are more likely to have return of erectile function in assorter time if they take these medications after surgery. The same medication is used to have a full erection, but this use is more for penile rehabilitation after surgery.
This study shows taking PDE5i also helps prevent the shortening of the penis by 4.4 mm. This is about 1/5 of an inch.
