Some studies have shown that resveratrol can affect hormone production and metabolism in animal models and in vitro (laboratory) settings. The idea that resveratrol might influence testosterone stems from several lines of research. Consequently, we find no support for the use of resveratrol in the treatment of benign prostate hyperplasia. The authors concluded that, although a considerable amount of research supports the positive impact of RSV on human and animal reproduction, further studies are necessary to consolidate the knowledge on the properties of RSV and its role in reproductive functions. Although many studies have investigated the beneficial effects of RSV on experimental animals, there are few clinical trials in humans on the relationship between this compound and male fertility and the results are often controversial . Indeed, the administration of micronized RSV in patients with cancer did not lead to serious side effects . Therefore, this review evaluated the effects of RSV on human male fertility and the mechanisms through which this polyphenol could act on human spermatozoa. Whilst research is limited to animal studies, it is definitely an areas of interest that warrants further investigation. The decrease in estrogen allows more room for testosterone to flourish therefore indirectly elevating it. Not only did it decrease its action, but also decreased production of estrogen at mRNA levels too. Resveratrol appears to boost male hormone levels by directly increasing T levels, and secondly by decreasing aromatization. The actual process of testosterone and other anabolic hormones converting to estrogen is called aromatization – something any man would want to avoid. It has also been claimed to increase lifespan, although this is anecdotal and not backed up by science. The bioflavenoid content of the nutrient has also been shown to decrease fat cell production, meaning that it may help long-term improve body composition. When levels of this hormone are within normal parameters you’ll find that you add muscle mass much easier and your strength will rapidly increase. It essentially protects the DNA within cells. It has antioxidant properties meaning it can fight excess free radical build up in the body. The supplements or the placebo was taken once daily after a meal as a complex agent in capsule form. 20 patients ages 29–78 years were enrolled, and after 6 men withdrew, 13 concluded the study without adverse events. The mechanism by which RSV improves cryopreserved sperm functions may relate to activation of AMPK, which is mainly localized in the post-equatorial region of the sperm head and the entire flagellum 34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,52,53. However, it is imperative to mention that these studies were done in healthy populations, and that may vary in sick patients. Otherwise, at doses of 2.5 g or more per day, side effects may occurs, like nausea, vomiting, diarrhea and liver dysfunction in patients with non-alcoholic fatty liver disease . All the above highlighted studies show the pivotal role of dose-dependency and aging in resveratrol-induced responses towards health benefits.
