Hydrogen Sulfide is better than viagra

Everyone knows by now that increasing the production of nitric oxide in the body results in a healthier cardiovascular system. One of the benefits of a healthy cardiovascular system for men is powerful erections on demand. For women, it’s a youthful sexual response and stronger orgasms.
Conventional wisdom indicates that nitric oxide is the main way to improve blood flow in the body. Nitric oxide can be enhanced by eating more vegetables that provide nitrates (like spinach and beets) or eating foods high in arginine or citrulline.
Scientists have found a new way to improve erections and that is by increasing the production of hydrogen sulfide. In fact Hydrogen Sulfide is better than viagra because you create it naturally in your muscles.
Here is a link to one study here.
Hydrogen sulfide (H2S), which is a well known toxic gas, has recently been recognized as a biological messenger, which plays an important role in physiological and pathophysiological conditions. Relatively high levels of H2S have been discovered in mammalian tissues. It is mainly synthesized by two enzymes including cystathionine β-synthase and cystathionine γ-lysase, which utilize L-cysteine as substrate to produce H2S. H2S has been demonstrated to exhibit potent vasodilator activity both in vitro and in vivo by relaxing vascular smooth muscle. Recently, H2S has been discovered in penile tissue with smooth muscle relaxant effects. Furthermore, other effects of H2S may play a role in the physiology of erection. Understanding of H2S in the physiology of erection might provide alternative erectile dysfunction (ED) strategies for those patients with poor or no response to type 5 phosphodiesterase inhibitors (PDE5i). This review intends to present the H2S pathway in penile tissue and the potential role of H2S in the physiology of erections.
In the article, Hydrogen Sulfide is created mainly by CSE acting on the amino acid Cysteine. What increases CSE? Exercise!

Exercise could be a therapeutic approach for cardiovascular dysfunction induced by estrogen deficiency. Our previous study has shown that estrogen maintains cystathionine-γ-lyase (CSE) expression and inhibits oxidative stress in the myocardium of female rats. In the present study, we investigated whether exercise improves CSE expression and oxidative stress status and ameliorates isoproterenol (ISO)-induced cardiac damage in ovariectomized (OVX) rats. The results showed that treadmill training restored the ovariectomy-induced reduction of CSE and estrogen receptor (ER)α and decrease of total antioxidant capacity (T-AOC) and increase of malondialdehyde (MDA). The level of CSE was positively correlated to T-AOC and ERα while inversely correlated to MDA. OVX rats showed increases in the serum levels of creatine kinase (CK) and lactate dehydrogenase (LDH) and the percentage of TUNEL staining in myocardium upon ISO insult compared to sham rats. Exercise training significantly reduced the serum levels of LDH and CK and the percentage of TUNEL staining in myocardium upon ISO insult in OVX rats. In cultured cardiomyocytes, ISO treatment decreased cell viability and increased LDH release, while overexpression of CSE increased cell viability and decreased LDH release in the cells upon ISO insult. The results suggest that exercise training improves the oxidative stress status and ameliorates the cardiac damage induced by oxidative stress in OVX rats. The improvement of oxidative stress status by exercise might be at least partially due to upregulation of CSE/H2S signaling.
