"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.
Though testosterone levels never reach zero (as estrogen levels do in women during menopause), low testosterone levels men to experience symptoms such as fatigue, low libido, and reduction of muscle mass.
While reduced testosterone is more prevalent in older men, it may occur in younger guys as well. Luckily, every one the causes of low testosterone in young guys are treatable, so if you encounter these symptoms at any age, there is no reason to ignore it.
For younger men, a fall in testosterone levels may be brought on by some illnesses, including type 2 diabetes, diabetes, chronic liver or liver disease, COPD or other lung disease, 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 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," says Bruce Gilbert, MD, PhD, an adjunct clinical professor of urology and reproductive medicine at Weill Cornell Medical College and director of reproductive and sexual medicine in the Smith Institute for Urology of the North Shore-LIJ Health System.
Additional causes of low testosterone in men 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 states. "This could be from a developmental issue, injury to the testicles, or radiation or chemotherapy treatment.
Can It Be 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.
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 younger men, we generally reserve treatment for people who have symptoms, such as fatigue and reduced 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 often used just in the short term, and when a doctor has close observation 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 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 which may increase their testosterone as well as maintain their sperm production," he says. 1 such choice is a category of drugs known as selective estrogen receptor modulators (SERMs).
Other treatments for low testosterone include weight loss and other lifestyle changes, like eating healthy and increasing exercise.
The bottom line, however, is that in the event that you have low testosterone symptoms, then it is very important to see your physician. Then, your doctor can rule out potentially more serious causes of your symptoms, including high blood pressure or a thyroid problem, and offer treatment that can improve your power and high quality of life.
