While physical anatomy and chemical reaction are both important for getting and keeping an erection, the brain is one of the most vital parts of this puzzle. "An erection is controlled by multiple areas of your brain, including the hypothalamus, limbic system and cerebral cortex," notes Axe. "Stimulatory messages are sent to your spinal erection centers and this facilitates an erection. When there's an issue with your brain's ability to send these important messages, it can increase the smooth muscle tone in your penis and prevent the relaxation that is necessary to get an erection."

Medications. There are several different ED medicines that can help produce an erection, such as avanafil (Stendra), sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). These medications work the same way: they relax smooth muscle and allow increased blood flow into the penis. Testosterone replacement and medications injected directly into your penis to help with erection are also common.
Men with a healthy lifestyle and no chronic disease had the lowest risk for erectile dysfunction; the greatest difference was seen for men aged 65-79. For instance, men who exercised at least three hours per week had a 30% lower risk for ED than those who exercised little. Obesity, smoking, and excessive TV watching were also associated with having a greater risk of erectile dysfunction.
Ginseng (Panax ginseng) opens the arteries, including those that carry blood into the penis. Korean researchers gave 90 ED sufferers one of three treatments: a placebo, an antidepressant (trazodone), or ginseng. The placebo and antidepressant groups showed 30 percent erection improvement, the ginseng group, 60 percent. Other Korean scientists repeated this study, giving a placebo or ginseng (2,700 mg/day) to 45 men with ED. After 8 weeks, the ginseng group reported firmer erections. However, 2,700 mg of ginseng might cause jitters and possibly insomnia.
If you find yourself with a man who is experiencing these problems, naturally, you might concern yourself with how to provoke and maintain their erection. This is often not not so much because you fear for your own personal enjoyment, but because you care about the pleasure and self-esteem of your partner. Follow these tips if you want to know more about how to handle a man who is impotent:
For many older men, issues like diabetes, hypertension and heart attacks are often contributing factors to erectile dysfunction. But Goldstein said that in younger men, ED is far more likely to stem from physical trauma. This could be the result of a sports injury, such as a misplaced karate kick, a surfboard hitting the wrong area or long-distance bike riding. It could also be a result of a sexual injury. (This is most common during heterosexual intercourse, especially in the woman-on-top position, the sex position dubbed "most dangerous" by a 2015 study.)
"Start by cutting out junk, processed and packaged foods. Instead, focus on eating high fiber foods, like fruit, vegetables, nuts and seeds, and foods that will help to improve blood flow, such as leafy green vegetables. It's also helpful to avoid drinking too much caffeine and alcohol. Next, make sure you are getting regular exercise. This will help you to balance your hormone levels, improve circulation and manage stress."

“Although having sex at 70 is not the same as having sex at 20, erectile dysfunction is not a normal part of aging,” according to Michael Feloney, MD, urologic surgeon and expert on sexual dysfunction issues at the Nebraska Medical Center in Omaha. “You should still be able to have a satisfying sex life as you age."
