What Causes Low Testosterone in Females?

Keep your testosterone levels optimal and reclaim your femininity

Low testosterone in females can be a big issue for both health and physical performance.

Gone are the days when we thought that higher natural testosterone levels would lead to masculinity, huge slabs of bulky muscle and facial hair that was worthy of the circus.

We now know that through exercise, nutrition and the right supplements you can create a lean, athletic and feminine physique that shows both your strength and your female power.

Low testosterone is an issue for many women.

But what causes it and why is it so bad for health and sports performance?


Testosterone and Females: An important hormone for health

It’s often referred to as the ‘male’ hormone. But that couldn’t be further from the truth.

Women still need testosterone to regulate everything from metabolic rate, muscle mass and bone health, to libido, mood and energy levels.

It decreases your risk of vascular, metabolic and even cognitive illness too.

You produce testosterone in 3 different parts of your body:

  • Ovaries
  • Adrenal glands
  • Peripheral tissues within your body

How is testosterone regulated in the female body?

Although testosterone (T) is produced in your ovaries and other tissues, it’s actually regulated by your brain.

Two glands in your brain called the hypothalamus and pituitary work together to make sure you have just the right concentration of hormones in your blood at any one time.

And if your T gets too low, these glands send a direct message (via a chemical communicator called luteinizing hormone) to your ovaries, adrenal glands and tissues to make more.

As levels increase again, they slow down these messages to stop levels getting t.

Testosterone is a naturally-occurring androgen hormone. It’s important for both health and physical well-being. But unfortunately, by the age of 45, as many as 90% of women suffer from low T.

The biggest drop in anabolic hormone production takes places between 20 and 40 years old.


But What Exactly Causes Low Testosterone in Females?

The exact reasons why your hormone levels might be lower than optimal could be varied.

But science tells us that there are a number of common causes of low testosterone that you need to be aware of.

Here’s what you need to know…

Oral contraceptive

With as many as 60% of females opting for the oral pill, it’s the most popular type of contraceptive out there.

It works by suppressing sex hormones such as estrogen and progesterone, but can also have a dramatic effect on testosterone levels too. More so if you take the pill for extended periods of time

Oral contraceptive can really  take it’s toll on hormonal balance.

The main cause of low testosterone in females from oral pill is that it elevates SHBG levels to an uncontrollable concentration.

This is a ‘scavenger’ protein that travels up and down your blood, looking for testosterone. And once it find it, it clings to it in a tight bear-hug manner, essentially stopping your body from using it.

Low progesterone levels

Your menstrual cycle is controlled by a number of hormones. all working in synergy to control your period, ovulation and phases of cycle throughout the month.

Progesterone is important as it helps you prepare for pregnancy during the luteal (last couple of weeks) phase of your cycle, as well as regulating the endometrium lining of your uterus.

What you might not know though is that progesterone and testosterone levels are closely linked in women.

When progesterone levels fall, so does testosterone. This is because some progesterone converts into androstenedione and then testosterone in your body.

If there isn’t enough progesterone, it’s difficult to make sufficient amounts of anabolic hormones too.


One unfortunate consequence of ageing is that your body can begin to function sub-optimally.

Your skin begins to lose its elasticity, your muscle and bone mass can decrease if you aren’t active and you’ll gradually lose the healthy body composition you once had.

By the time you reach the menopause, your testosterone levels could have halved. Your ovaries struggle to remain as hormonally active, and your pituitary gland doesn’t fire messages as well as it used to.

But there are ways to fight back and ageing doesn’t always mean you’ll suffer from low T.

Other reasons

  • Adrenal insufficiency – essentially your adrenal glands can’t produce enough anabolic hormones
  • Early menopause
  • Genetics – some women don’t produce enough DHEA or DHEA-S – important precursors to testosterone
  • Hypopituitarism – your pituitary gland can’t signal your body to make enough testosterone
  • Surgical removal of ovaries

How Can You Tell If Your Testosterone Levels Are Low?

Some of the more common symptoms of low testosterone in females include:

  • Low mood, anxiety and depression
  • Reduced libido, sex drive and satisfaction (you can’t reach orgasm as well as you used to)
  • Loss of energy, irritability, lethargy and constant tiredness
  • Loss of muscle mass
  • Increased body fat

How is low testosterone in females diagnosed?

Unfortunately, many women choose not to get checked out for low hormone levels. This can lead to a ‘suffer in silence’ mentality that will leave you looking and feeling at your worst.

For your health practitioner to say you’ve got low testosterone, you’ll need to have some blood tests.

Dependant on your doctor, you might be sent for these tests on a few occasions across your menstrual cycle, as fluctuating hormone levels can affect the results.

If your total testosterone falls below the low-end cut off of 25 ng.dL you’ll be diagnosed as having low testosterone.
