"After age 30, most men begin to experience a gradual decline in testosterone," states 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 libido, and reduction of muscle mass.
While reduced testosterone is more prevalent in older men, it may occur in younger guys also. Luckily, every one the causes of low testosterone in young men are treatable, so if you experience 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 may be brought on by some ailments, such as type 2 diabetes, diabetes, chronic liver or liver disease, COPD or other lung disorder, or adrenal gland issues, based on Dr. Samadi.
Genetic causes of low testosterone in men include the diseases Klinefelter syndrome, Kallmann syndrome, Prader-Willi syndrome, and Myotonic dystrophy. Another disorder that 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 at the Smith Institute for Urology of their North Shore-LIJ Health System.
Additional causes of low testosterone in males younger than 50 include pituitary gland tumors, HIV infection, 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.
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€
"When it comes to treating low testosterone in older men, we generally reserve treatment for those who have symptoms, such as fatigue and reduced libido," Gilbert says.
In these circumstances,"therapies are usually used just in the short term, and if 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 wish to give 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 consider alternatives which may increase their testosterone as well as maintain their sperm production," he states. 1 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 healthy and raising exercise.
The bottom line, however, is that in the event that you have low testosterone symptoms, then it is important to see your physician. Then, your doctor can rule out more significant causes of your symptoms, such as high blood pressure or a thyroid problem, and give treatment that can improve your power and high quality of life.
