low testosterone Systems - Insights

There's a good reason men go girl-crazy in their teens and twenties: Their testosterone levels are at their Bonuses peak. From that point, go now though, try this out testosterone levels gradually decrease.

"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 loss of muscle mass.

While reduced testosterone is more common in older men, it may occur in younger guys as well. Luckily, all the causes of low testosterone in young guys are treatable, so in the event that you experience these symptoms at any age, there is no reason to ignore it.


For younger men, a fall in testosterone levels can be brought on by some illnesses, including type 2 diabetes, diabetes, chronic liver or liver disease, COPD or other lung disease, or adrenal gland issues, 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 that could result in low testosterone is hemochromatosis, which makes 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," says 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.

Additional causes of low testosterone in males younger than 50 include pituitary 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. In secondary hypogonadism, the testicles are normal but function improperly because of a problem with the hypothalamus or pituitary gland."

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.


If you suspect low testosterone, the first step is to see your primary care physician.

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.


Not everyone with low testosterone needs treatment. "When it comes to treating low testosterone in older guys, we generally reserve treatment for those who have symptoms, such as fatigue and low 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. Such testosterone supplements come in the form of gel, injections, patches, long-acting pellets, or oral inserts.

In these circumstances,"treatments are usually used only in the short term, and when a doctor has close observation and understanding of the individual," Gilbert says.

An important consideration for younger men before getting treatment is fertility. "You do not wish to offer supplemental testosterone to guys who are interested in being 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 consider alternatives which may 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, like eating healthy and increasing exercise.

The bottom line, though, is that if you have low testosterone symptoms, it's important to see your doctor. Then, your doctor can rule out potentially more serious causes of your symptoms, such as high blood pressure or a thyroid problem, and give treatment that could enhance your power and quality of life.
