Dr. Virginia Loewenstine, CEO and medical director of Tristate Preventive Health, answers your questions

Q: Is there a link between low testosterone and mental health?

A: Yes. More and more studies are supporting this. Low testosterone can occur in both men and women, and it doesn’t affect libido only. Besides physical conditions that include bone, muscle and hair loss, decreased sperm count, sleep problems and fatigue, low testosterone can also cause mood swings, “brain fog,” and an inability to concentrate. Most concerning is that it has been found to cause depression.

Low testosterone can be diagnosed with a simple blood test, and more and more departments are adding this to their annual physicals.
