Former mixed martial artist James Wilks believes a plant-based diet improved his erectile function.
The Ultimate Fighter winner made the comments in an interview with LADbible.
When asked if 'he had noticed a difference in the downstairs department' as a result of ditching animal products, Wilks said he had.
"I do feel like it did improve, erectile function, but I've got no evidence - I haven't measured my erections," he explained.
The Game Changers
The issue of erectile function was explored in a scene in The Game Changers - which Wilks recently produced and starred in. The sports documentary, which is available to watch on Netflix, is directed by Oscar-winner Louie Psihoyos and executive produced by Oscar-winner James Cameron.
The scene shows urologist Dr. Aaron Spitz, author of The Penis Book, oversee an experiment in which three men wore special devices to monitor penile length and girth overnight, first after eating a meal with meat in it, then after eating a plant-based meal.
The experiment indicated that the men had better duration and rigidity of erections after eating plants.
Speaking about the scene in an interview early last year, James Cameron revealed it was one of favorites - branding it the 'peter meter scene' in an interview with Toronto-based newspaper The Star.
Keen to promote the benefits a plant-based diet can have in the bedroom, he added: "I'd love to put Viagra out of business, just by spreading the word on plant-based eating."
