Sexual Health is recognized by The World Health Organization as “an integral part of overall health, well being, and quality of life.” So why do so many men “hang it up” when we can’t keep it up? Perhaps we think we are just getting too old? It doesn’t have to be that way. Like general health, a decline in sexual health, including erectile dysfunction, does typically decline with age, but there are ways to slow down the hands of time with a proactive strategy of “Sexual Anti-Aging”.

Erectile dysfunction

So why does the flag fly at half-mast? An erection occurs when blood is pumped into two elongated chambers that create the shaft of the penis. As the blood pressure rises in the cylinders they expand and then when the pressure is high enough, they become hard, like an inflated tire. The most common cause of a problem getting or keeping an erection is due to weak blood flow due to narrowing of the arteries.

Many conditions can lead to this including diabetes, high blood pressure, and heart disease. In fact, having trouble getting an erection may be your first and only warning sign of a looming heart attack or stroke. At only one millimeter in diameter, these arteries are a fraction of the size of the coronary arteries that supply blood to your heart muscle or the carotid arteries that supply blood to your brain, so the penis can be the first to go, well before a heart attack or stroke.

Decreased sensitivity 

Your nerve endings atrophy over time and so your penis will become less sensitive with age. This should come as no surprise considering all our senses dim as we get older. The drop off is gradual so for most of us, we don’t really notice it as it’s happening. But over time it’s normal to require more stimulation to get and keep an erection as well as to reach sexual climax.

If you have other medical causes of erectile dysfunction, the decreased sensitivity adds insult to injury. There are specialized vibrators to consider which are designed to heighten stimulation just prior to intercourse.

Age also steals your testosterone

Not everyone, but most men will make less and less testosterone over time. Testosterone is important for sexual desire as well as helping the nerves and blood vessels to function optimally. Too little sleep[1] or sleep apnea[2] reduces your body’s natural production of testosterone. Early to bed, early to “rise.” There are many men who require testosterone supplementation to restore them to normal levels. Fortunately, this can be done very safely with proper medical supervision. This is typically in the form of an injection or a gel or lotion that is rubbed on the skin.


From the day you enter this life, your cells are under attack from a process called oxidation. This is the same process that causes steel to rust. The attack comes from molecules called “free radicals.” The natural balance of smooth muscle and collagen in your blood vessels is destroyed over time by free radicals and smooth muscle cells disappear and get replaced by more and more collagen making your blood vessels stiff and narrow. Fortunately, your body has a defense mechanism.

Molecules known as “antioxidants” are naturally produced to block those free radicals from doing their damage. One of the key anti-oxidants is Nitric Oxide (NO). It is produced from the very innermost lining of the blood vessels called the “endothelium.”

As you age, your ability to both produce nitric oxide and to benefit from it declines. Scientists call this “endothelial dysfunction.” Poor food choices, bad habits such as smoking and being sedentary, as well as toxins in our environment all dump more free radicals into our system.

This process occurs as early as the late 20s in men but isn’t typically noticeable until their 40s by which time about 40 percent of men will have some degree of an erection problem, usually on the milder side. As decades pass, the percentage of men with erectile dysfunction goes up in lockstep. So, 50% of men have some degree of a problem at age 50 and 60% of men have some degree of a problem at age 60 and so on[3]. The severity of the problem also worsens with age.

What are potential ways to halt or delay the onset of age-related erectile dysfunction? 

A comprehensive review in the journal Translational Andrology and Urology sheds light on the topic: [4]

Good nutrition and exercise are key to slowing the ravages of time. Fresh, unprocessed vegetables, fruits, nuts, legumes, and whole grains are the best food sources of nitrates and thousands of other molecules many of which are key “antioxidants” which counteract the aging process. Nitrates are converted to NO in the blood and along with antioxidants work at the level of the cell’s mitochondria to stave off age-related damage to the smooth muscle of the blood vessels.

Regular exercise also triggers the release of NO and other antioxidants[5]Excess fat, on the other hand, releases toxic free radicals so staying lean is key as well. Most of my very advanced aged patients are “skinny old men.” Excess fat can also reduce testosterone levels by turning it into estrogens, the female hormones.

Kegel exercises. Although the penis isn’t a muscle, there are muscles around the base of the penis that automatically squeeze to keep the blood trapped in the erection and also during ejaculation. These muscles get weaker with age, but you can pump them up with Kegel “squeezes”. This is the same move you make when you are trying to hold back your urine, but you do it on purpose several times in a row several times a day.

The sooner you put into practice good nutrition and exercise the sooner you claw back some time. Its never “too late” but the fact is that the body takes time to repair itself, and there is some degree of deterioration that is simply not reversible.

What about nutritional supplements?

Nutritional supplements may play a role as well. Several plant sources have been studied for their potential to boost NO and in a recent study at UCLA and the most potent source was ginger. Certain Brazilian plants have been touted to boost erections for years, so the research team at UCLA studied a combination supplement of ginger with two other plant sources from the Amazon, guarana, and Muira puama, along with L-citrulline, an amino acid that promotes NO production as well. When aging rats were given the supplement and the tissue in their penis was studied, the smooth muscles in the blood vessels looked the same or even better than in younger rats![6]

Human preclinical studies with this combination, known as Revactin, have shown boosted NO production in human penis tissue and a statistically significant increase in self-reported sexual function in men taking it over several months[7].

Medications, surgery and other measures

For many, the changes in sexual function with age will require medication and for a few even surgery. Fortunately, these treatments are very safe and very effective. Prescription medications for erectile dysfunction may have different side effects but they all work in the same way, by increasing the effect of NO in the penis blood vessels. They work for about 65% of men. For most of the remaining men, erections can be restored with an injection or a urethral suppository whose main ingredient, prostaglandin, also boosts NO in the penis. There is also a vacuum erection device that can be placed temporarily on the penis to draw blood in and make it erect. Surgical implants are an excellent solution when other treatments don’t work.

As one of my colleagues once quipped,

Nothing in life is certain except death, taxes, and erections- if you really  want them.”
