Nettle root extracts are known for their ability to restore normal production of important sex hormones, such as testosterone. The primary action of nettle root is linked to its action on the glands that produce testosterone. Nettle root contains serotonin and acetylcholine, both of which directly stimulate testosterone production and boost the functioning of these vital glands.
A study published in May 2014 in The Journal of Sexual Medicine found that some men can reverse erectile dysfunction with healthy lifestyle changes, such as exercise, weight loss, a varied diet, and good sleep. The Australian researchers also showed that even if erectile dysfunction medication is required, it's likely to be more effective if you implement these healthy lifestyle changes.
