"After age 30, most men begin to experience a gradual decline in testosterone," says David Samadi, MD, chairman of the urology department at Lenox Hill Hospital in nyc.
Although testosterone levels never reach zero (as estrogen levels do in women during menopause), low testosterone levels men to experience symptoms like fatigue, low sex drive, and reduction of muscle mass.
While low testosterone is more prevalent in older men, it can occur in younger guys also. Fortunately, every one of the causes of low testosterone in young men are curable, so if you encounter these symptoms at any age, there is no reason to dismiss it.
For younger men, a fall in testosterone levels may be caused by some ailments, such as type 2 diabetes, chronic liver or kidney disease, COPD or other lung disorder, or adrenal gland problems, according to Dr. Samadi.
Genetic causes of low testosterone in males include the ailments Klinefelter syndrome, Kallmann syndrome, Prader-Willi syndrome, and Myotonic dystrophy. Another disease which can cause low testosterone is hemochromatosis, making the body store 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 at the Smith Institute for Urology of the North Shore-LIJ Health System.
Additional causes of low testosterone in males younger than 50 contain adrenal gland tumors, HIV infection, and radiation therapy or chemotherapy for cancer.
Doctors categorize causes of low testosterone as secondary or primary.
"Primary hypogonadism stems from a problem in the testicles," Samadi states. "This could be from a developmental issue, injury to the testicles, or radiation or chemotherapy treatment.
Can It Be Low Testosterone?
Regardless of the reason, 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 generally reserve treatment for those who have symptoms, such as tiredness and low libido," Gilbert says.
In these circumstances,"treatments are often used just in the short term, and if a physician has close monitoring and understanding of the patient," Gilbert says.
An important consideration for younger men before getting treatment is fertility. "You do not wish to offer supplemental testosterone to guys who want to be fertile because 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. "Hence, men of reproductive age should think about alternatives that might increase their testosterone as well as preserve their semen production," he states. 1 such alternative is a class of drugs called selective estrogen receptor modulators (SERMs).
Other treatments for low testosterone include weight loss and other lifestyle modifications, like eating healthy and raising exercise.
The main point, however, is that if you have low testosterone symptoms, it is very important to see your physician. Then, your doctor can rule out potentially more serious causes of your symptoms, including hypertension or a thyroid problem, and give treatment that can enhance your power and high quality of life.
