In the last 100 years, life expectancy for men has increased by 65 percent, according to the Centers for Disease Control and Prevention (CDC).
In 1900, men lived until about
Regular exercise, a healthy diet, and adequate rest all help maintain energy and vitality in men over 50. But men are also turning to one of the most advanced aging solutions available. Over the last decade, testosterone use among middle-aged and senior men has become popular.
Testosterone is the hormone responsible for the development of male external genitalia and secondary sexual characteristics. It’s produced by the testicles. Testosterone is important for maintaining:
- muscle bulk
- bone density
- red blood cells
- sexual and reproductive function
Testosterone also contributes to vitality and well-being.
As men age, their bodies gradually produce less testosterone. This natural decline starts around age 30 and continues throughout the rest of a man’s life.
Some men have a testosterone deficiency called male hypogonadism. This is a condition in which the body doesn’t produce enough testosterone. It may be caused by problems in the:
- pituitary gland
Men at risk for this condition include those who have had an injury to the testicles or have HIV/AIDS. If you’ve gone through chemotherapy or radiation therapy, or had undescended testicles as an infant you are also considered at risk for hypogonadism.
Symptoms of male hypogonadism in adulthood include:
- erectile dysfunction
- decrease in muscle mass
- loss of bone mass (osteoporosis)
- decrease in beard and body hair growth
- development of breast tissue
- difficulty concentrating
- decreased sex drive
Doctors can determine if you have male hypogonadism through physical exams and blood tests. If your doctor detects low testosterone they may perform additional tests to determine the cause.
Treatment typically includes testosterone replacement therapy (TRT) in the form of:
TRT reportedly helps to:
- boost energy levels
- increase muscle mass
- restore sexual function
However, scientists caution there isn’t enough information to determine the safety of regular testosterone supplementation.
Many men experience changes as they age similar to the symptoms of hypogonadism. But their symptoms may not be related to any disease or injury. Some are considered a normal part of aging, such as:
- changes in sleep patterns and sexual function
- increased body fat
- reduced muscle
- decreased motivation or self-confidence
The Mayo Clinic reports that TRT can help men with hypogonadism. The results are not as clear with men who have normal levels of testosterone or older men with decreasing testosterone levels. More rigorous studies are needed, according to the Mayo Clinic.
Studies are mixed on whether TRT is beneficial for normal men as they age. Some research has brought up serious risks with the therapy, particularly when taken long term. This has led doctors to be cautious about recommending it.
A large, 2010 meta-analysis of 51 studies looked at the safety of TRT. The report concluded that safety analysis of TRT is of low quality and fails to inform the public about potential long-term effects.
The Mayo Clinic cautions that TRT also may:
- contribute to sleep apnea
- cause acne or other skin reactions
- limit sperm production
- cause testicle shrinkage
- enlarge the breasts
- increase the risk of heart disease
There are also risks involved in having low testosterone levels, such as:
- heart attack
- hip fracture
Previously, there were concerns that TRT raised the risk of developing prostate cancer.
Most current data, including two
If you have male hypogonadism or low testosterone, talk with your doctor about whether TRT may be a good option for you. Discuss the risks and benefits of TRT.
If you don’t have hypogonadism, but you’re interested in feeling more energetic and youthful. The following alternative methods may help increase your testosterone level without the use of hormone therapy.
- Maintain a healthy weight. Overweight men are more likely to have low testosterone levels. Losing weight can bring testosterone back up.
- Exercise regularly. Sedentary men tend to have reduced levels of testosterone, as the body doesn’t need as much. Weightlifting can stimulate testosterone production. The key is regularly moving your body and using your muscles.
- Sleep 7 to 8 hours every night. Lack of sleep affects the hormones in your body.
- Try vitamin D supplements. A
2011 studyof 165 men suggested that supplementing with about 3,300 IUs of vitamin D per day increased testosterone levels.
- Enjoy your morning coffee. There is
some 2008 evidencethat caffeine may increase testosterone levels.
- Get more zinc. Zinc deficiency in men has been associated with hypogonadism.
- Eat more nuts and beans. They’re rich in D-aspartic acid, which promotes the production of testosterone, according to one
One way to increase your testosterone levels is through TRT. It’s especially effective if you have hypogonadism. Studies have not yet demonstrated the effectiveness of TRT in helping men with normal levels of testosterone or older men with decreasing testosterone levels due to aging.
Men who take TRT usually experience increased energy, a higher sex drive, and overall well-being. But its long-term safety hasn’t been established.
There are a variety of lifestyle treatments involving exercise, diet, and sleep that have been shown to increase testosterone levels. Talk to your doctor about what may be best for you.
