How to Reduce Testosterone Levels

Testosterone is the primary male sex hormone, responsible for regulating sex drive, increasing muscle mass, and decreasing body fat levels. According to the American Cancer Society, one major reason for wanting to lower testosterone levels is being affected by certain diseases such as prostate or bone cancer. Regardless of whether your reasons are medical or personal, there are steps you can take to lower your natural production of testosterone.

Instructions

• 1

  Increase your consumption of soy products to naturally lower your testosterone levels. According to a study published in the Journal of Endocrinology, soy intake had a negative effect on circulating levels of testosterone. Thus, you should strive to consume at least one or two soy products per day to reduce your testosterone levels. Consider soybeans, mizo, tofu, and any other natural soy products.

• 2

  Consult with your doctor about the possibility of going on low-dose anti-androgens such as Eulexin or Casodex. While anti-androgens will not lower the amount of testosterone that is produced by your body, they will act to prevent your body from being able to utilize the testosterone produced--having the same general effect as reducing your overall output of testosterone.

• 3

  Consider talking with your physician about starting a luteinizing hormone-releasing drug such as Lupron or Eligard. These drugs are generally more expensive than anti-androgens and require more frequent check-ups with your doctor, but the result might be worth it if you are dedicated to decreasing your testosterone levels. These drugs prevent the body from producing testosterone by cutting off your body's supply at the source.

  Consider surgical castration if you are a man looking to permanently decrease testosterone levels. While this is an extreme step and should be carefully considered before undergoing, it might be worth it if you do not have the time nor the inclination to stick to a schedule of prescription medications and dietary measures to decrease your testosterone levels.
