"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.
Though 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 reduced testosterone is more common in older men, it may occur in younger men also. Fortunately, every one of the causes of low testosterone in young guys are curable, so in the event that you encounter such symptoms at any age, there is no reason to ignore it.
Causes of Low Testosterone in Younger Men
For younger guys, a fall in testosterone levels can be brought on by some illnesses, including type 2 diabetes, diabetes, chronic liver or kidney disease, COPD or other lung disorder, or pituitary gland issues, 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 which could 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," says 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 include pituitary gland tumors, HIV infection, 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. "This could be from a developmental issue, injury to the testicles, or radiation or chemotherapy treatment. In secondary hypogonadism, the testicles are normal but function improperly because of a problem with the hypothalamus or pituitary gland."
Is It Low Testosterone?
Irrespective of the reason, low testosterone symptoms are 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€
Treatments for Low Testosterone in Younger Men
Not everyone with low testosterone needs treatment. "When it comes to treating low testosterone in older guys, 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 physician has close monitoring and understanding of the individual," Gilbert says.
An important consideration for younger men before getting treatment is fertility. "You do not wish 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. "Therefore, men of reproductive age should consider alternatives that might increase their testosterone as well as preserve their semen production," he states. 1 such choice is a category of drugs called selective estrogen receptor modulators (SERMs).
Other treatments for low testosterone include weight loss and other lifestyle changes, such as eating healthier and increasing exercise.
The bottom line, though, is that if you've got low testosterone symptoms, then it is very important to see your doctor. Then, your doctor can rule out potentially more serious causes of your symptoms, such as hypertension or a thyroid problem, and give treatment that could enhance your energy and quality of life.
