Does Testosterone Make You Last Longer in Bed?

Categories :

Testosterone is the hormone that leads you confidently from a boy to a man. It pushes you courageously from a timid teen to a confident, assertive and chiseled example of masculinity.

But as you hit your thirties your body naturally begins to slow down production of this vital androgen.

The result? A slow journey to belly fat, loss of muscle and of low libido.

Is there anything you can do? Most definitely.

Being aware of the ways in which you can keep your testosterone levels elevated can change your life for the better.

And in this article we take a look at the relationship between hormones and bedroom performance. Can testosterone make you last longer?

In this article we take a look…

Testosterone Makes You a Man

Testosterone (T) is a naturally-occurring steroid hormone released into the bloodstream by the testes. It is an anabolic-androgenic hormone in that it is responsible for not only masculinity, but also synthesising energy into muscle and bone mass too.

How does testosterone work?

When your body senses that it needs more testosterone in the bloodstream, a complex series of event is put in place. These are controlled by a system called the hypothalamic-pititary-gonadal (HPG) axis feedback loop.

And whilst there’s a lot to know about this system, here are the most important take home points:

  • The first step is for a part of your brain called the hypothalamus to kick start T production by producing a hormone called gonadotropin-releasing hormone (GnRH).
  • This hormone acts as an alarm clock for another part of the brain called the pituitary gland. GnRH wakes up the next hormone called luteinizing hormone (LH).
  • LH is a little bit more like a courier with a long-haul delivery. The reason why is LH has to take a message all the way to the testes the brain – that’s a long way.
  • The testes receive LH after its long journey, realize the body would like more T making, and specific cells called Leydig cells produce more.

Once T enters your bloodstream it needs to find a home. It’s the role of androgen receptors (AR) to grab any T they can from the blood and push it into the corresponding cells so it can do its job.

It’s a complex system but if it works effectively you’ll reap all of the rewards that this powerful hormone can offer.

Androgenic, anabolic characteristics

As you approach early teen years your body begins to go through various changes. These are characteristics of puberty.

  • Your testes and penis get bigger
  • Your voice gets deeper
  • Body hair begins to develop
  • You hit peak height velocity and see rapid increases in your height
  • Your shoulders get broader, you develop muscle mass and get much stronger

At this point, and through to your late twenties, you’re the epitome of the male physique – like Michelangelo’s David, carved from stone.

Testosterone Naturally Declines As You Age

As you hit the age of thirty, your T levels naturally begin to plummet – by around 2% per year. According to research, as many as 40% of men aged over 45 suffer from the symptoms of low testosterone

And by the age of 60, that number is well over 50%.

What are the symptoms of low T?

  • Loss of muscle, bone mass and strength
  • Increase in belly fat and ‘man boobs’
  • Increased risk of long-term metabolic and vascular health
  • Loss of sexual performance and libido

Low T is a slippery slope to poor health, physical performance and decreased cognitive ability.

But the biggest effects are on your bedroom ability –  low sex drive, a drop in physical performance and non-existent love life. There’s also the overall worry and anxiety that comes with it.

But could testosterone be the key to having better sex and lasting longer in the bedroom?

Key Point: Testosterone is the hormone responsible for both anabolic and androgenic characteristics.

Can Testosterone Help Improve Sexual Performance?

Higher test means an increased libido

One of the biggest obstacles you might find when T levels are low is actually wanting to have sex in the first place. You’ll constantly feel tired, low on energy and lethargic – the last thing on your mind is spending any intimate time with your partner.

Because low T level are thought to be one of the biggest contributors to poor sex drive, there’s been a lot of research into the relationship between the two.

And one of the biggest studies found that there was a “significant relationship between testosterone and sexual function, mood and strength” [1].

The Result: T will help you get in the mood.

Boost T levels to improve sexual function

An interesting research project published in the the Journal of Sexual Medicine [2] wanted to look at the link between men with hypogonadism (clinically low T levels) and sexual desire and function.

The research team recruited 22 men with low T – on average they were 58 years old and had suffered from decreased sexual desire for around 4 years.

Each of the men received testosterone-boosting supplementation until their free T levels were back to normal (this took only 6-8 weeks). They were asked to report their sexual appetite 24-weeks after the study started, based on a scoring system called the International Index of Erectile Function (IIEF).

There some astonishing findings when the results were published. Practically all of the men reported an improvement in libido and sexual desire, with over 50% also reporting better erectile function too.

The Result: T will improve sexual desire and function.

Stronger erections

Not only does elevating your testosterone boost libido and sexual appetite, it can also help you in the physical department too. After all, it doesn’t matter how much you want it if the machinery doesn’t let you ‘put in it place’.

A study from the journal Reviews in Urology [3] found that there was a definite correlation between low T and erectile dysfunction. 

In the detailed and comprehensive report, researchers suggested that the most likely cause of erectile dysfunction was hypogonadism. But that treatment with testosterone-boosting supplements would help sexual function return to normal.

Erections are clearly testosterone-dependent, as evidenced by the observation that men with hypogonadism have a marked reduction in the frequency, amplitude, and rigidity of erections

The Result: T will improve erection strength and symptoms of erectile dysfunction.

Key Point: Fixing your testosterone can improve your libido, sexual performance and erection strength.

Can You Correct Your Testosterone Levels?

Although T levels fall with age, there are studies that suggest it isn’t age itself  that lowers hormone levels, but simply that poor diet and lack of physical activity is catching up [4].

Lower levels of testosterone in men could be more likely a result of behavioral and health changes than by aging. And that’s good because whilst you can’t control your age you can control your lifestyle.

Age-related hormone decline may be decelerated through the management of health and lifestyle factors.

Being motivated to change your lifestyle and diet can help you make drastic changes to your testosterone levels – and all of the benefits that come with it.

So don’t accept your ever-decreasing hormone levels are just a product of age. Make changes now and reap the rewards forever.
