Testosterone, the primary sex hormone in males, is known for causing physical changes during puberty. Many are not aware that it can also affect sex drive, mood, muscle mass, and bone density.

Testosterone levels tend to drop in all men as they age. In fact, according to research, about four out of 10 men over age 45 have low testosterone, or “low T.”

Here’s what you— and the people who love you — should know about this common condition:

What causes low T?

Many things can cause low testosterone, such as:

  • Aging. It’s normal for testosterone to decrease as you age.
  • Injury to the testicles, or surgery or radiation treatment in the groin area.
  • Certain medicines.
  • Having a long-term medical condition, such as high blood pressure, diabetes, kidney or liver disease, coronary artery disease or obesity.
  • Problems related to the pituitary gland or hypothalamus.
  • Low testosterone also can be present at birth.

A blood test is usually done to find out if you have low testosterone. If your doctor thinks low testosterone could be related to another medical problem, other tests may be done.

Since testosterone normally decreases with age, your doctor can help determine whether your symptoms are from low testosterone and whether you could benefit from treatment.

What are the symptoms of low T?

Symptoms may include loss of decreased libido, erectile dysfunction, and low energy. Other symptoms may include a depressed mood, the loss of muscle mass and body hair, increased body fat, weakened bones, breast discomfort, and hot flashes. If you’re experiencing these symptoms and suspect it could be due to low T, consult with your doctor.

Is low T preventable?

A lifestyle that promotes good cardiovascular health may promote normal testosterone levels. This includes things like a heart-healthy diet, exercise, not smoking, and blood pressure monitoring and control.

How is low T treated?

There are many available options for testosterone replacement, including topical gels and patches, injections, and long-acting testosterone supplements. However, testosterone supplements may increase PSA (prostate-specific antigen) levels, causing those with large prostates to experience worsening of symptoms. Additionally, testosterone replacement can cause low sperm count, so it should not be used when trying to conceive.

Through open communication and collaboration with your primary care physician, personalized treatment plans can be crafted aimed at restoring hormonal balance and improving your quality of life. Seeking medical guidance not only addresses immediate concerns but also promotes proactive management of age-related changes, fostering a healthier and more fulfilling aging journey!
