- Factors that influence sexual health include mood, energy level, nutrition, genetics, age, health conditions and medications
- Endurance cardio exercise, such as running marathons, actually lowers testosterone production
Some clinicians believe that factors like obesity, stress and inadequate sleep probably play a role in such issues. This isn't purely a lifestyle issue; these factors are also possible causes of low levels of the hormone testosterone, which can influence sexual function.
"Low T" is still most common in older men. Known as male menopause or andropause, this gradual decrease in testosterone typically occurs steadily over time. In fact, "after age 40, men experience a 3% reduction in testosterone every year," naturopathic doctor Geovanni Espinosa said. "After age 60, about 20% of men experience andropause."
According to some estimates, the average 80-year-old man will have about 50% less testosterone
than he did as a young guy. As a result, men may experience problems such as insomnia, weight gain, decreased muscle and bone density, anger and depression, as well as decreased libido and other sexual problems.
That said, low testosterone isn't necessarily just a consequence of aging. A number of factors can have an impact on a man's testosterone levels, as Espinosa writes as one of the contributors to the new book "Integrative Sexual Health
," edited by Dr. Andrew Weil. The book notes that many factors influence sexual health, including mood, energy level, nutrition, genetics, age, health conditions and medications.
One option for low testosterone is prescription testosterone-replacement therapy, but this approach can have worrisome side effects, such as decreased sperm production and shrinkage of the testicles. "Testosterone, like all hormones, has multiple actions on many body functions and on the mind," Weil said. "In my opinion, it should be taken -- and prescribed -- only to correct a deficiency documented by appropriate blood tests."
