The Relationship Between Testosterone and Sex Drive

Testosterone is a hormone that’s gotten kind of a bad rap over the years. It’s been inaccurately tied to rage in the news and is often thought to be a male “problem” instead of accepted as a vital player in not only human growth and development, but in optimal health, performance, and disease prevention.  

When misused or abused, testosterone can cause health problems. But when prescribed correctly and dosed appropriately by an expert, it can be life-changing – in a good way!

In truth, testosterone is a critical hormone in both men and women and plays an essential role in the bodily processes and overall health of both. While it’s not responsible for rage, when it’s too high or too low, it does affect multiple body systems that influence everyday functions, causing problems like:

  • Fatigue
  • Weakness
  • Increased body fat
  • Mood changes
  • Loss of muscle mass

And of course, it plays an essential role in growth and sex characteristics in men, including:

  • Bone mass
  • Changes during puberty, like deepening voice, facial hair, pubic hair
  • Development of male sex organs
  • Libido (sex drive)
  • Muscle size and strength
  • Sperm production

So while sex isn’t testosterone’s only job, you can see that it’s critical for the development of male characteristics, including – yes – your sex drive.

How Does Testosterone Affect Sex Drive?

While testosterone is a key player in regulating your sex drive directly, it also has an indirect influence through its effect on other body systems.

Testosterone indirectly affects your sex life by improving your physical and emotional state:

  • An adequate amount of testosterone helps decrease fat mass and increase muscle size and strength, which can mean more stamina.
  • Stabilizing testosterone can help elevate your mood, improve your relationships, and increase your interest in sexual activity.
  • Increasing low levels can help you sleep better and avoid fatigue, giving you more energy throughout the day.

More energy, a better mood, and more stamina can all help you feel better, improve your relationships, and improve your desire to have sex.

More directly, testosterone:

  • Helps combat erectile dysfunction
  • Improves erections
  • Stimulates the male sex drive

It all adds up – when you feel your best physically and emotionally and are physically prepped for better erections and a stronger libido, your sexual well-being is optimal.

So, what happens when something’s just not right?

High Testosterone and Sex Drive

A high testosterone level isn’t a common problem. That may be partly because it’s hard to say what’s considered a normal or high level because testosterone fluctuates throughout the day and over time. So, one man’s highs and lows might not even affect another man.

Still, abnormally high levels can occur and may cause health problems, including:

  • Acne
  • Enlarged prostate and difficulty urinating
  • Fluid retention, swelling of the legs and feet
  • Hair loss
  • Low sperm count
  • Testicular shrinkage

When it comes to testosterone or any hormone, too much is too much of a good thing. Balance is the key.

Low Testosterone and Sex Drive

Testosterone levels tend to drop as you age, as the testes produce less. Even though it’s not the only factor behind your sex drive, it can have the unwelcome effect of decreasing your ability to have satisfying sex by lowering your sex drive and causing erectile dysfunction

Low testosterone can cause other noticeable symptoms, like:

  • Breast tissue growth
  • Decreased muscle mass
  • Depression, irritability, poor concentration
  • Hot flashes
  • Loss of body and facial hair

And it’s easy to see why some of those could affect your interest in sex along with the lower libido and erection problems.

What Causes Your Testosterone Level to Drop?

The decline in testosterone as you age is not even noticeable to some men, but if levels fall low enough, most men will notice a decrease in sex drive.

Aging isn’t the only cause for a drop in testosterone levels, however. Certain conditions or diseases affecting the testes or the pituitary gland and hypothalamus may affect testosterone levels, including:

  • Autoimmune conditions
  • Environmental toxins
  • Castration
  • Infection
  • Injury to the testes
  • Radiation or chemotherapy for male cancers
  • Some medications
  • Tumors

Understanding the cause can help you get to the bottom of the problem. When aging is the cause, hormone replacement therapy may be the ticket to getting back what you’re missing.

How Can Testosterone Therapy Improve Your Sex Life?

If low testosterone affects your mood, erections, and sex drive, hormone therapy can help you regain your ability to have satisfying sex and enjoy more intimate relationships again. When prescribed by a specialist in therapeutic doses, testosterone can be highly beneficial to your health and overall functioning. Age-related hormonal decline is a medical problem, and just like any other medical problem, you shouldn’t be embarrassed to treat it. You don’t have to just live with it.

Testosterone therapy can:

  • Boost your mood 
  • Increase stamina
  • Decrease fat mass and increase muscle size and strength 
  • Help you sleep better
  • Reduce fatigue
  • Increase your sex drive and desire
  • Improve erectile function

If you have a low sex drive, decreased sexual performance, or unsatisfying sex, you should have a complete hormonal evaluation, including a physical exam and measurement of total testosterone, free testosterone, DHEA, sex hormone-binding globulin, LH, human growth hormone, and other key hormones.

Testosterone doesn’t work alone, so addressing it as though it’s the only hormone affecting your sex life only addresses part of the problem.
