"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 New York City.
Although testosterone levels never reach zero (as estrogen levels do in women during menopause), low testosterone levels men to experience symptoms such as fatigue, low sex drive, and loss of muscle mass.
While low testosterone is more common in older men, it may occur in younger guys as well. Luckily, every one of the causes of low testosterone in young men are curable, so in the event that you experience such symptoms at any given age, there is no reason to dismiss it.
For younger men, a fall in testosterone levels may be brought on by some illnesses, including type 2 diabetes, 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 men include the ailments Klinefelter syndrome, Kallmann syndrome, Prader-Willi syndrome, and Myotonic dystrophy. Another disorder that can result in 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 in 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 disease, and radiation therapy 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.
Is It Low Testosterone?
Irrespective of the reason, low testosterone symptoms would be the same.
"Symptoms include low libido, erectile dysfunction, fatigue, decreased mental acuity, and moodiness," Dr. Gilbert states.
"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 your blood test reveals low testosterone (usually defined as a level lower than 300 ng/dL), the doctor may treat you or refer you to a specialist, such as a urologist or endocrinologist.
Treatments for Low Testosterone in Younger Men
"When it comes to treating low testosterone in older men, we generally reserve treatment for people who have symptoms, such as tiredness and low libido," Gilbert says.
Such testosterone supplements come in the form of a gel, injections, patches, long-acting pellets, or oral inserts.
In these circumstances,"treatments are usually used only in the short term, and when a doctor has close monitoring and knowledge of the individual," Gilbert says.
An important consideration for younger men before getting treatment is fertility. "You don't want to offer supplemental testosterone to guys who are interested in being 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 consider alternatives which may increase their testosterone as well as maintain their semen production," he says. 1 such alternative is a class of drugs known as selective estrogen receptor modulators (SERMs).
Other remedies for low testosterone include weight loss and other lifestyle changes, such as eating healthier and raising exercise.
The main point, however, is that in the event that you've got low testosterone symptoms, it's very important to see your physician. Then, your doctor can rule out potentially more significant causes of your symptoms, including high blood pressure or a thyroid problem, and give treatment that can enhance your power and quality of life.
