Testosterone Replacement Therapy

Testosterone Replacement Therapy

Have you been feeling like you are running on an empty tank?  Have you felt low on energy? Have your workouts not been like they used to or have you stopped seeing the gains that you were once having?  Have you heard about low testosterone and wondered if you have it?  Find out what you need to know about testosterone, what symptoms are associated with low testosterone and most importantly, if you could have low testosterone.

 What is testosterone?
Testosterone is the primary male hormone or androgen that is produced in the testicles.  Although testosterone is generally referred to as a sex hormone, testosterone actually governs several areas within the body including a man's development from birth onward with responsibility for everything from determining gender, through pubertal changes and male potency (libido & sexual functioning), to the partitioning of bodily muscle and fat distribution.

What are the normal levels of testosterone?

Normal testosterone levels range between 350ng/dl and 1,000ng/dl however there is a variation between normal testosterone levels and optimal testosterone levels.  Optimal testosterone levels are actually 700ng/dl and 1,100ng/dl but they also vary according to age.  

What is low testosterone in men?
Low testosterone is exactly what it says.  It is when the body makes too little testosterone. As men age, testosterone levels begin to decline.  In fact, in males, peak testosterone levels are achieved by the age of 20 after which they plateau and then slowly begin to decline through the years.  In some males, testosterone levels can decline more rapidly.  When the levels of testosterone get too low, that is when the symptoms of low testosterone develop.  The medical term for this is “androgen deficiency,” but what is exactly the range in which low testosterone is diagnosed?  Unfortunately, this number is variable.  As a general rule, a testosterone level greater than 500 is considered healthy.  This does not mean that you cannot have symptoms of low testosterone with these levels. The symptoms of low testosterone do not necessarily correlate with the levels of total testosterone but more so with the levels of free testosterone.  Free testosterone is the testosterone that is actually available to work in the body as the rest is tied up to a protein.  As the levels of free testosterone drop below 15, the symptoms of low testosterone begin to develop.   

What causes low Testosterone in men?

  1. Normal aging
  2. Injury or infection affecting the testicles (which make most of the testosterone in men)
  3. Certain treatments for cancer, including radiation, chemotherapy, and hormone therapy for prostate cancer
  4. Disorders that affect the pituitary gland, a gland at the base of the brain that controls all hormone-producing organs
  5. Other medical problems, such as liver and kidney disease, obesity, diabetes, AIDS and other rare genetic problems 

What are the symptoms of low testosterone?

The symptoms of low testosterone are different depending on how long a man has had low Testosterone. Initial symptoms of low testosterone may include: 

  1. Feel tired, especially at the end of the day
  2. Decreased exercise endurance
  3. Have little or no interest in sex (also called “low libido”)
  4. Decreased erections or absence of morning erections
  5. Feel sad, down, or depressed 
  6. Mood irritability
  7. Weight gain

As testosterone levels continued to decline, men develop other symptoms of low testosterone or medical problems, including: 

  1. Loss of muscle or difficulty gaining muscle
  2. Bone thinning
  3. Loss of facial or body hair
  4. Growing breasts (also called “gynecomastia”)
  5. Low sperm count or infertility
  6. Low Bone Mineral density

If I have these symptoms, should I see a doctor or nurse?

Yes, if you have symptoms of low testosterone, come by our offices to get your blood drawn to measure your testosterone levels. There are many things that can cause those symptoms.  A simple blood test can show whether you have low testosterone and we will have an answer typically within 24 hours.

How do you diagnose low testosterone?

Low testosterone is diagnosed with a combination of test.  The first test is quite simple and straight forward.  You simply fill out a simple survey or questionnaire that determines whether or not you have symptoms that could be attributed to low testosterone levels.  Once the presence of these symptoms are confirmed, your doctor might order some blood work to confirm the diagnosis of low testosterone.  These test include total testosterone levels as well as free testosterone levels.  Follicle-stimulating hormone (FSH) and Luteinizing hormone (LH) are also typically ordered to ensure that proper testicular stimulation is present and that the lack of testosterone production is secondary to decreased testosterone production rather than decreased testicular stimulation.

Can low testosterone in men be treated?

Low testosterone can be treated with testosterone replacement therapy, which comes in shots, patches, gels, and tablets you put on your gums. But low testosterone is not always treated, especially in men older than 60. That’s because it’s normal for testosterone to drop in men as they age. In fact, normal aging causes some of the same changes that happen in men with low testosterone, such as less energy or interest in sex.

So if you think you might have low testosterone or have already been told that your testosterone levels are low, come by and get started and start enjoying your new you. We provide a personalized approach to your therapy and make every effort to accommodate you at any time for your scheduled therapy

What can I expect after starting testosterone replacement therapy?

  2. Increase muscle strength and Decreased fat mass:  Testosterone replacement also leads to substantial improvements in muscle strength and fat-free mass in suffering from Low Testosterone

There are several different forms. Testosterone can be given in an injection (shot), patch, gel, or tablet you put on your gums.  Men who use testosterone replacement patches, gels, or tablets must wash their hands after putting on the medicine. That’s because testosterone can get on other people’s skin. It can cause harmful side effects, especially in children. Patches and gels must be put on skin that is covered by clothes. This can help keep testosterone from getting on other people.
