"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 sex drive, and reduction of muscle mass.
While low 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 treatable, so in the event that you experience such symptoms at any given age, there's no reason to dismiss it.
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 disease, or adrenal gland problems, according to Dr. Samadi.
Genetic causes of low testosterone in males include the diseases Klinefelter syndrome, Kallmann syndrome, Prader-Willi syndrome, and Myotonic dystrophy. Another disease which 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 sexual medicine at the Smith Institute for Urology of their North Shore-LIJ Health System.
Additional causes of low testosterone in men 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 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 an urologist or endocrinologist.
Treatments for Low Testosterone in Younger Men
"When it comes to treating low testosterone in younger men, we generally reserve treatment for people who have symptoms, such as tiredness and low libido," Gilbert says.
In these circumstances,"treatments are usually used only in the short term, and when a doctor has close observation and knowledge 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 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 improve their testosterone in addition to maintain their semen production," he states. 1 such choice is a category of drugs known as selective estrogen receptor modulators (SERMs).
Other remedies for low testosterone include weight loss and other lifestyle modifications, such as eating healthier and increasing exercise.
The bottom line, however, is that in the event that you've got 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, such as hypertension or a thyroid problem, and give treatment that could enhance your energy and quality of life.
