Testosterone is a hormone produced primarily in the testes in men and helps with bone density, fat distribution, muscle strength, red blood cell production and sperm production, the Mayo Clinic explains. Testosterone, which declines after the age of 40, is thought to increase strength in men and has been used for sore joints including the knees.There is no association between testosterone and knee strength in women. Before trying testosterone therapy, work with your doctor to weigh the risks and benefits.
Functions
The National Institutes of Health did a study using sex hormones and anterior knee laxity. They found that increasing serum testosterone levels relax tension in the knees. The National Institutes of Health also found that older men undergoing knee replacement surgery showed that preoperative testosterone therapy reduced the number of days for recovery. More studies are still needed regarding men and knee strength, therefore testosterone therapy is still considered experimental.
Dosage
If you begin using testosterone supplements for sore knees, it is important to discuss dosage with your doctor. Testosterone will mostly likely be used in a gel form and applied directly to the sore knee at the same time every day, the University of Maryland Medical Center explains. Be sure to store the gel in a closed container at room temperature, away from heat, moisture, and direct sunlight. If you miss an application, and you have less than 12 hours until your next dosage, it is important to not apply extra medicine to make up for a missed dose.
Side Effects
The Mayo Clinic warns that testosterone supplements may cause sleep apnea, increase red blood cell production, limit sperm production and cause acne. The University of Maryland Medical Center also warns that supplemental testosterone may increase the risk of prostate cancer, especially if it is used in older men. Be sure to discuss side effects and warnings with your family physician before using testosterone.
