An estimated 30 million American men have sexual dysfunction issues. Since L-arginine has been shown to help relax arteries and improve blood flow, it may also help with sexual problems. Sexual dysfunction can be caused by a number of factors including: hormonal imbalance, decreased circulation, depression, or anxiety. Science has revealed that high cholesterol, high blood pressure, diabetes, being over-weight, and smoking not only are the leading indicators for heart disease, but also are gauge for sexual dysfunction.
Role of NO and Sex
Nitric oxide (NO) has been found to play a role in developing an erection. Sexual Enhancement Drugs, like the blue pill, raise sensitivity to the increase in NO that occurs with sexual stimulation. The amino acid L-Arginine, which occurs naturally in food, helps to increase the body's production of nitric oxide, a compound that makes erections possible by dilating blood vessels in the penis.
Supplement developers have designed formulas that are thought to elevate NO levels naturally with supplementation of the amino acid L-Arginine. Arginine has been shown to increase nitric oxide levels in the body including the penile area.
“The amount of nitric oxide produced in the penis, and thus the ability to have an erection, is directly related to the availability of arginine.”
-The Harvard Health Letter
L-Arginine for Sexual Health
Preliminary findings by the National Institute of Health indicate that the favorable cardiovascular effects of nutraceuticals, including L-Arginine, might also reflect on male sexual function, however, studies in this area remain underexplored. Men with known cardiovascular problems are advised to take supplements only with a doctor's supervision.
Researchers contemplate that nitric oxide “can correct up to 90% of all penile dysfunction." Erections are the outcome of an increase in blood supply to the penis. NO allows for the vasodialation required for an erection to occur and likewise the reverse problem, sexual problems, can be caused by a deficiency of nitric oxide.
“80% of sexual dysfunction in men and women is directly attributable to some form of nitric oxide failure brought on by smoking, prescription drugs, diabetes, high blood pressure, high LDL cholesterol and obesity (35 pounds overweight). Ironically, these are the same risk factors for heart disease and stroke.” -New England Journal of Medicine
While ED is a medical diagnosis, prescriptions are not necessary for men who have experienced a decline in sexual performance but do not suffer from a diagnosable problem. Interestingly, prescription male enhancement pills do not produce nitric oxide, nor do they increase sexual desire. Herbal supplements that combine the amino acid L-Arginine with other natural aphrodisiacs have gained popularity among men with sexual problems. It has been suggested to increase sex drive supplement with 3,000- 5,000 mg of L-Arginine daily.
Arginine for Women Too
Researchers at Stanford University School of Medicine discovered that L-Arginine works to increase levels of nitric oxide in the body and is a probable indicator molecule for sexual arousal. Their study showed L-Arginine significantly improved women’s sexual desire and overall sexual satisfaction.
Supplementation with 5,000 mg of L-Arginine has been shown to enhance male and female libido and sexual desire. Additionally, it has been found to enhance sexual performance.
Enhanced Sexual Performance
5,000 mg of L-Arginine daily has been known to enhance and shown in some studies to:
- Stimulate the production of nitric oxide, the endogenous chemical that stimulates erections in males
- Improve sperm count and sperm motility
- Enhance male and female libido
- Enhance female sexual performance - nitric oxide facilitates female orgasm
- Improve male sexual performance by boosting the nitric oxide (no) molecule that is integral to the achievement of erections
- Produce erections that are bigger, harder and more frequent. It also helps to increase male sexual endurance
- May improve prostate function
