"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 libido, and loss of muscle mass.
While reduced testosterone is more prevalent in older men, it may occur in younger men as well. Fortunately, all of the causes of low testosterone in young men are curable, so if you encounter these symptoms at any given age, there is no reason to dismiss it.
Causes of Low Testosterone in Younger Men
For younger men, a drop in testosterone levels can be brought on by some ailments, such as type 2 diabetes, diabetes, chronic liver or kidney disease, COPD or other lung disorder, or pituitary gland problems, based on Dr. Samadi.
Genetic causes of low testosterone in men include the ailments Klinefelter syndrome, Kallmann syndrome, Prader-Willi syndrome, and Myotonic dystrophy. Another disorder that could 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 their 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 secondary or primary.
"Primary hypogonadism stems from a problem in the testicles," Samadi states.
Can It Be Low Testosterone?
Irrespective of the cause, low testosterone symptoms are 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. Your doctor can diagnose low testosterone with a blood test.
Treatments for Low Testosterone in Younger Men
Not everyone with low testosterone needs treatment. "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.
Such testosterone supplements come in the form of gel, injections, patches, long-acting pellets, or oral inserts.
In these circumstances,"therapies are usually used only in the brief term, and when a doctor has close monitoring and knowledge of the patient," Gilbert says.
An important consideration for younger men before getting treatment is fertility. "You don't want to offer supplemental testosterone to men 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 which may improve their testosterone in addition to maintain their semen production," he says. One such alternative is a category of drugs called selective estrogen receptor modulators (SERMs).
Other treatments for low testosterone include weight loss and other lifestyle modifications, such as eating healthier and raising exercise.
The main point, however, is that if you've got low testosterone symptoms, then it's important to see your doctor. Then, your doctor can rule out more significant causes of your symptoms, such as high blood pressure or a thyroid problem, and offer treatment that could enhance your power and high quality of life.
