Testosterone is a hormone produced in the human body, in ovaries by women but primarily by men within the testicles.

Testosterone affects a man’s appearance and is required for sexual development. It is also responsible for body mass, sperm production, and sex drive. According to our friends at MedicineNet, testosterone peaks during early adulthood in normal developing males. Once you reach age 30, testosterone levels naturally begin slowly decline by approximately 1% a year. A normal range of testosterone is typically 300–1000 nanograms per deciliter (ng/dL). Low testosterone is diagnosed when levels fall below 300 ng/dL.

The American Urological Association estimates that every 2 out of 10 men over the age of 60 are living with low testosterone. A blood test is used to accurately determine your level of circulating testosterone. Men can experience a range of symptoms when testosterone decreases lower than it should.

The clues aren’t always cut and dry so it is important to follow up with your doctor if you are experiencing:

• low sex drive,
• issues in achieving or maintaining erection,
• low semen production,
• hair loss,
• fatigue,
• change in sleep pattern,
• increased body fat,
• decreased bone density,
• or changes in mood.

What Options are available after an official diagnosis of low testosterone?

Testosterone replacement therapy (TRT)
As with any treatment, TRT comes with its own set of possible side effects that need to be taken into consideration before proceeding. Besides the obvious sexual benefits, TRT can improve mood and strengthen bone density. Men undergoing testosterone therapy should be aware of the increased risk of blood clots and stroke. Other side effects may include acne and sleep apnea. Men using a testosterone gel must ensure that they thoroughly wash their hands after application and that no person touches the application site for 2 to 4 hours.
