Testosterone Q & A

What is testosterone?

Testosterone is a hormone produced mainly in the testicles. It supports many critical bodily functions in men, including:

  • Body and facial hair
  • Bone density
  • Libido
  • Muscle mass
  • Red blood cell production
  • Sperm production

Testosterone levels are highest during the teen years into early adulthood. Around the age of 30, testosterone levels begin to decline about 1% every year.

The adrenal glands and ovaries produce testosterone in women. Testosterone produces hormones that regulate the menstrual cycle and contributes to the creation of red blood cells. The FDA has not yet approved treatments for women with low testosterone.

How does low testosterone affect men?

Signs of low testosterone in men include:

  • Decreased libido
  • Difficulty concentrating
  • Irritability
  • Increased body fat
  • Low energy/Fatigue
  • Reduced muscle mass and strength
  • Sleep disruption
  • Mood changes, including depression


Decreased testosterone is an inevitable part of the aging process. It can also be a symptom of other medical problems, including specific genetic disorders, diseases, or damage to the pituitary gland or testicles. Thyroid problems, sleep apnea, depression, and diabetes produce symptoms similar to those in men with low testosterone.

Is testosterone replacement right for me?

Dr. Velazquez tests testosterone levels for most men over 30 or with any symptoms of concern. If a blood test confirms low testosterone, he performs a comprehensive exam to determine why your levels have dropped. Because testosterone levels change throughout the day, additional tests may be needed to assess your levels.

Men with medical conditions causing a significant drop in testosterone may benefit from testosterone therapy. Oral medication, patches, gels, or injections are used to supplement testosterone and improve symptoms.

Some men see an improvement in energy level, mood, muscle mass, and sex drive after testosterone replacement, while others don’t experience any benefits. Men with low testosterone who are otherwise healthy should discuss the pros and cons of replacement with Dr. Velazquez.

Because every patient and their symptoms are unique, Dr. Velazquez treats low testosterone on a case-by-case basis. You age, symptoms, and overall health all factor into your treatment plan.
