"After age 30, most men begin to experience a gradual decline in testosterone," states David Samadi, MD, chairman of the urology department at Lenox Hill Hospital in nyc.
Though testosterone levels never reach zero (as estrogen levels do in women during menopause), low testosterone levels men to experience symptoms like fatigue, low libido, and reduction of muscle mass.
While reduced testosterone is more prevalent in older men, it may occur in younger guys also. Luckily, every one the causes of low testosterone in young men are treatable, so in the event that you encounter these symptoms at any given age, there is no reason to dismiss it.
For younger men, a drop in testosterone levels can be brought on by some ailments, such as type 2 diabetes, diabetes, chronic liver or liver disease, COPD or other lung disorder, or pituitary gland problems, according to Dr. Samadi.
Genetic causes of low testosterone in men include the ailments Klinefelter syndrome, Kallmann syndrome, Prader-Willi syndrome, and Myotonic dystrophy. Another disease which can cause low testosterone is hemochromatosis, which makes the body shop too much iron.
"Low testosterone can also result when something happens, like trauma or steroid use, that prevents the testes from making the hormone," states Bruce Gilbert, MD, PhD, an adjunct clinical professor of urology and reproductive medicine at Weill Cornell Medical College and director of reproductive and reproductive medicine in the Smith Institute for Urology of the North Shore-LIJ Health System.
Other causes of low testosterone in males younger than 50 contain adrenal gland tumors, HIV disease, and radiation treatment or chemotherapy for cancer.
Doctors categorize causes of low testosterone as primary or secondary.
"Primary hypogonadism stems from a problem in the testicles," Samadi says. "This could be from a developmental issue, injury to the testicles, or radiation or chemotherapy treatment.
Can It Be Low Testosterone?
Irrespective of the cause, low testosterone symptoms would be the same.
"Symptoms include low libido, erectile dysfunction, fatigue, decreased mental acuity and moodiness," Dr. Gilbert says.
"Younger men with low testosterone usually come to me and say, ‘I can't work out like I used to, and I've lost interest in sex.’ â€
If you suspect low testosterone, the first step is to see your primary care physician.
"When it comes to treating low testosterone in older men, we usually reserve treatment for people who have symptoms, such as fatigue and reduced libido," Gilbert says.
In these circumstances,"treatments are often used only in the brief term, and when a physician has close observation and understanding of the patient," Gilbert says.
An important consideration for younger men before getting treatment is fertility. "You do not want to give supplemental testosterone to guys who want to be fertile since it can turn off sperm production," Gilbert says.
Once a young man goes off testosterone supplementation, there's a chance his sperm count will never return to what it was before he started. "Therefore, men of reproductive age should think about alternatives that might improve their testosterone as well as maintain their semen production," he says. One such choice is a class of drugs known as selective estrogen receptor modulators (SERMs).
Other treatments for low testosterone include weight loss and other lifestyle modifications, like eating healthier and raising exercise.
The bottom line, though, is that in the event that you have low testosterone symptoms, then it is important to see your physician. Then, your doctor can rule out more significant causes of your symptoms, such as hypertension or a thyroid problem, and give treatment that can improve your power and quality of life.
