Did you know that a cock ring can help you maintain an erection? This O-shaped toy fits around your penis and helps keep blood in the shaft, where you want it. A cock ring also helps prevent venous leakage, a form of erectile dysfunction where blood flows to your penis, but has trouble staying there. (Giddy, a new cock-ring-like gadget designed to treat ED, may also help guys with venous leakage maintain stronger erections.)
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.
Like going bald, ED becomes more common as men age. According to the National Institutes of Health, about 5% of all 40-year-old men have ED and that number rises with age. Between 15% and 25% of 65-year-old men have ED. This is one of the reasons you see so many ED drug commercials during televised sporting events, Fox News programs, and other shows that typically attract men over 50 (just kidding, Fox).
In an article on Men’s Health about things that wreck your erection, some examples of threats to an erection are sugar, lack of sleep, sleeping near a newborn baby, and lack of vitamin D. The common theme in the article is that reduced testosterone impacts your erection. Not all scientists agree with that. But there are definitely links between testosterone and erectile problems.
