Dear Friends and Neighbors,

CentraCare care givers have been working around the clock for more than 20 months to care for you, your families and friends during COVID. We are committed to caring for every Minnesotan who needs us, and nothing will prevent us from doing so – even during these never-seen-before times.

The challenge of providing this level of care is that our hospital beds are often full. ERs in all of our hospitals are packed. And our clinical teams are exhausted. Early in the pandemic, our community stepped up in amazing ways to help us. We ask that you again join us in fighting this pandemic together.

How can you help?

  • Please get your COVID vaccines and booster shots. They are proven safe and effective in reducing COVID illness, keeping people out of the hospital, and preventing death.
  • If your situation is not an emergency, please use other care options, including:
  • If this is a medical emergency, call 9-1-1, or visit the ER.

Together, we can do this. Thank you for your support.

Ken Holmen, MD
President and CEO

The benefits and risks of testosterone therapy

Published in Urology, Sexual Medicine, Men's Health Author: Elizabeth Phillips,MD

Testosterone is known as the “male hormone” but is present in both men and women. In men, it is produced mainly in the testicles.

Testosterone effects:

  • Muscle strength and mass
  • Facial and body hair
  • Sex drive
  • Sperm production
  • Bone density
  • Fat distribution
  • Red blood cell production
  • Exercise tolerance
  • Mood

Testosterone levels usually peak during adolescence and the early 20s and gradually decline with age. Low testosterone levels may be due to a problem with the testicles or the pituitary gland (in the brain) that controls production of testosterone.

In older men, low testosterone levels may represent the normal aging process. This is known as “hypogonadism of aging.” A health care provider can help determine if a low testosterone level needs to be treated. There are benefits and risks to testosterone therapy and each person’s personal health situation must be considered carefully.

Men with low testosterone may experience:

  • loss of sex drive
  • erection problems
  • sleep problems
  • difficulty with exercise
  • weakened bones
  • depressed mood
  • less energy or motivation

Some of these signs and symptoms may be caused by other factors such as medication side effects, thyroid problems, diabetes, obstructive sleep apnea or depression. A blood test is the only way to diagnose a low testosterone level.

Health care providers may prescribe testosterone in the form of injections, patches, pills, pellets or gels. People receiving testosterone replacement therapy often experience an increase in energy, sex drive, sleep and muscle mass.

The side effects of the therapy may include:

  • symptoms of an enlarged prostate, such as trouble urinating
  • blisters, itching, or redness on the skin (if using a patch or a gel)
  • reduced or absent sperm production (infertility)
  • sleep apnea
  • acne

People can naturally increase their testosterone level by practicing good health habits, such as:

  • healthy diet
  • good sleep hygiene
  • regular exercise
  • stress management

If you think you could be experiencing low testosterone levels, or to find out if you’d be a good candidate for replacement therapy or to learn more, please talk with your health care provider.
