"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 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 loss of muscle mass.
While reduced testosterone is more prevalent in older men, it may occur in younger guys also. Fortunately, every one of the causes of low testosterone in young guys are curable, so in the event that you experience these 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 may be caused by some illnesses, including type 2 diabetes, diabetes, chronic liver or liver disease, COPD or other lung disorder, or pituitary gland issues, 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 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," states 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 at the Smith Institute for Urology of the North Shore-LIJ Health System.
Other causes of low testosterone in males younger than 50 contain adrenal 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. 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 cause, low testosterone symptoms would be the same.
"Symptoms include low libido, erectile dysfunction, fatigue, decreased mental acuity and moodiness," Dr. Gilbert says.
"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 usually reserve treatment for those 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 doctor has close observation and knowledge of the individual," Gilbert says.
An important consideration for younger men before getting treatment is fertility. "You do not want to give 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. "Hence, men of reproductive age should consider alternatives which may increase their testosterone as well as maintain their semen production," he states. 1 such choice is a class of drugs known as selective estrogen receptor modulators (SERMs).
Other remedies for low testosterone include weight loss and other lifestyle modifications, such as eating healthy and raising exercise.
The main point, however, is that in the event that you've got low testosterone symptoms, then it is important to see your physician. Then, your doctor can rule out potentially more significant causes of your symptoms, including hypertension or a thyroid problem, and give treatment that can improve your energy and quality of life.
