"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 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 also. Luckily, every one the causes of low testosterone in young guys are curable, so in the event that you encounter 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 problems, according to Dr. Samadi.
Genetic causes of low testosterone in men include the diseases Klinefelter syndrome, Kallmann syndrome, Prader-Willi syndrome, and Myotonic dystrophy. Another disorder which could result in low testosterone is hemochromatosis, which makes 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 their North Shore-LIJ Health System.
Other causes of low testosterone in men younger than 50 include pituitary gland tumors, HIV disease, and radiation therapy 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. 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€
Your doctor can diagnose low testosterone with a blood test.
"When it comes to treating low testosterone in older men, we usually reserve treatment for people who have symptoms, such as fatigue and reduced libido," Gilbert says.
In men who don't make the hormone in their testes because of a condition such as Klinefelter syndrome, or those who have lost their testes because of cancer, the only option is testosterone replacement therapy.
In these circumstances,"therapies are usually used just in the short term, and if a physician has close observation and understanding of the patient," Gilbert says.
An important consideration for younger men before getting treatment is fertility. "You do not want to offer supplemental testosterone to men 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 in addition to preserve their semen production," he says. 1 such alternative is a category of drugs called selective estrogen receptor modulators (SERMs).
Other remedies for low testosterone include weight loss and other lifestyle changes, such as eating healthy and increasing exercise.
The main point, though, is that in the event that you've got low testosterone symptoms, it is 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 improve your power and quality of life.
