Testosterone is the primary male sex hormone. Side effects of too much testosterone may include a higher risk of prostate cancer, rapid heart rate and nervousness, and agitation. It is the elevated risk of prostate cancer that prompts some men to want to lower their testosterone levels, which begin to fall naturally when a man reaches his late forties.
Talk with your doctor about the merits of reducing your testosterone level and whether lifestyle changes might help you reach this goal. Your doctor can help you create a plan for lowering testosterone.
Take any medications as prescribed by your physician, including drugs to lower testosterone and mood-altering medications that can provide calming effects in individuals with too much testosterone.
Change your diet. Eat less red meat and fewer dairy products, which contribute to testosterone production, and eat more fish and vegetables. Consume soy milk and tofu as dairy substitutes.
Get married or become involved in a long-term, monogamous relationship. Studies show married men and males in stable relationships have lower testosterone levels and fewer health problems overall than single men.
Exercise more than usual. If you are in good shape, consider increasing your workout regimen, which will help lower testosterone.
Drink alcohol. Moderate consumption of red wine inhibits testosterone production. One or two glasses per day are within the safe range.
Smoking tobacco products and marijuana have been clinically shown to lower testosterone, but are not recommended as long-term solutions.
