Note that PLC is also beneficial for those with diabetes related ED:
Quote from: PubMedCONCLUSION: PLC plus sildenafil was more effective in reducing SI and endothelial dysfunction markers in patients with type 2 diabetes and ED.

Quote from: PubMedCONCLUSIONS: Salvage therapy with PLC plus sildenafil was more effective than sildenafil in the treatment of ED in patients with diabetes refractory to sildenafil monotherapy.

Quote from: Life Extension Magazine (a commercial supplement site)The combination of 2 grams each of PLC and acetyl-L-carnitine daily was more effective than testosterone at improving nocturnal penile tumescence and the International Index of Erectile Function score, an important measure of erectile and sexual function. PLC and acetyl-L-carnitine thus appear to be safe, effective agents for managing male sexual dysfunction.42

I had a very modest, but measurable, improvement in my own "ED" (in quotes because I have not had complete ED, but "flagging erection quality" - softer than it used to be), using these supplements.
I did not see any change in my Peyronies. The other issue I have with these studies is that they seem to come from only Italy, and have not been verified in a multi-center, double blinded, placebo controlled study. Given the lack of efficacy that others are finding with Verapamil iontophoresis, for example, it makes one wonder about the veracity of Italian data in general.
