Low Testosterone in Women: Causes, Symptoms, and Treatment
Testosterone is commonly recognized as a male hormone. However, women also have testosterone — albeit in smaller quantities — and it plays a number of vital roles in the female body.
When women don’t have enough testosterone, it can lead to several symptoms.
Many symptoms of low testosterone cause pain and discomfort. A deficiency of this hormone can also have psychological and emotional effects on women — potentially impacting their quality of life.
In this article, we will explore the causes of low testosterone in women, the symptoms associated with this deficiency, and the available treatments.
What is Testosterone?
Testosterone belongs to a class of hormones called androgens that are responsible for the development of secondary sexual characteristics in men such as facial and pubic hair, deepening of the voice, and increased muscle mass.
In men, testosterone is primarily produced in the testes. In women it is produced in the ovaries and adrenal glands.
Although women have significantly lower testosterone levels than men, this hormone has a vital role in a woman’s body, including regulating:
Libido
Blood cell production
Muscle mass
Bone strength and health
Energy levels
Mood
Hair and skin growth
Metabolism
Cholesterol levels
Reproductive function
For this reason, too little or too much testosterone can have a great impact on a woman’s overall health.
What Causes Low Testosterone in Women?
Also known as hypoandrogenism, a testosterone deficiency in women has both primary and secondary causes.
Primary causes
The primary causes of testosterone insufficiency are:
Polycystic ovary syndrome (PCOS): A hormonal disorder where women experience imbalanced levels of androgens, which disrupt normal ovarian function. As testosterone is produced in the ovaries, PCOS can interfere with the production of this hormone.
Women who have had their ovaries removed: Women who've had their ovaries surgically removed — through a procedure known as an oophorectomy — may experience low levels of this hormone.
Aging: As women age, their ovarian function declines, which can lead to lower levels of testosterone being produced. Postmenopausal women, in particular, have an increased risk of experiencing low testosterone levels.
Adrenal insufficiency: Also known as Addison's disease, this condition is related to the adrenal glands, where some testosterone is produced in women. While this disease primarily involves the adrenal glands, it can also affect hormonal balance.
Congenital conditions: Genetic disorders such as congenital adrenal hyperplasia (CAH) can lead to disruptions in the production of androgens by the adrenal glands.
Secondary causes
Low testosterone levels in women can also be caused by these factors:
Hormonal imbalances: Conditions like a malfunctioning pituitary gland (hypopituitarism) can disrupt the hormones that stimulate the ovaries to produce testosterone. Chronic stress can also disrupt the release of hormones.
Certain medications: Some birth control pills, as well as glucocorticoids, can lower testosterone levels. Glucocorticoids are steroid medications like prednisone.
Chronic illnesses: Conditions such as type 2 diabetes and chronic kidney disease (CKD) can cause hormonal disturbances associated with low testosterone in women. Ongoing inflammation in the body from illness can also affect hormone production.
Lifestyle factors: Excessive physical exertion, a significantly low body weight, and obesity can lead to hormonal imbalances.
Alcohol and substance abuse: These behaviors may disrupt endocrine function, potentially leading to low testosterone levels.
What are the Symptoms of Low Testosterone in Women?
As mentioned above, testosterone plays an important role in many functions in the body. So, a deficiency of this hormone would naturally cause unpleasant symptoms and health problems.
While researchers have explored the effects of excess testosterone in women, there is little scientific research into low testosterone symptoms.
It’s important to note that not all these symptoms may appear together and every woman will experience them differently. Some may have mild symptoms while others may have more pronounced effects.
Low libido
In both men and women, testosterone is associated with sexual desire. Without testosterone, there is a reduced activation of the part of the brain known as the hypothalamus, which is involved in sexual arousal.
Low sexual desire in women can lead to less sexual intimacy, which can put a strain on the relationships they have with their partners.
Fatigue and low energy levels
Testosterone helps to regulate energy levels because it influences muscle mass and metabolism — two factors that impact our energy.
Lower levels of testosterone can lead to feelings of fatigue and low energy. This can make it challenging to stay alert and complete daily tasks.
Mood changes
Our moods are somewhat impacted by the amount of testosterone in the body. It also affects the brain’s neurotransmitter systems.
For this reason, low testosterone levels can lead to mood swings, irritability, and an increased risk of mood disorders such as depression. Changes in muscle mass and strength
As an anabolic hormone that promotes muscle protein synthesis, a lack of testosterone can result in muscle loss and decreased physical strength.
Weight gain
Low testosterone can lead to unwanted body fat, especially around the abdomen.
This is because testosterone helps regulate how the body metabolizes fat, and a deficiency can lead to an imbalance between muscle and fat.
Hot flashes
The hypothalamus is largely responsible for body temperature. Lower levels of testosterone in women can impact this brain structure and result in hot flashes.
Sleep disturbances
Hormonal imbalances, including low testosterone, can interrupt the sleep-wake cycle. This can disrupt an individual’s natural sleeping patterns, potentially making it difficult to fall or stay asleep.
Changes in the skin and hair
Testosterone has a direct impact on skin health and hair growth. A deficiency in this hormone can result in thinning hair and dry skin.
It can also cause changes in the quality of the hair and skin.
Vaginal dryness and discomfort
Another important role that testosterone plays in women’s bodies is the health of the vaginal tissues and lubrication.
Reduced testosterone levels can lead to less lubrication, causing potential dryness and pain during sexual intercourse.
Menstrual pattern changes
A significant part of the regulation of the menstrual cycle relies on testosterone. So, low levels of this hormone can disrupt menstrual cycles, possibly resulting in irregular periods or changes in menstrual flow.
Cognitive problems
While research on this is limited, there is some evidence to suggest that low testosterone levels may impact cognitive functions — such as memory and mental clarity — in women. This is potentially due to how hormones influence brain function.
Bone health problems
Testosterone promotes bone density in women. Low levels of this hormone can increase a woman’s risk of osteoporosis and bone fractures, especially in postmenopausal women.
Key Point: Testosterone and Fertility
Some research suggests that low testosterone levels may affect fertility in women. This is because inadequate testosterone levels can disrupt ovarian function and menstrual cycles, potentially resulting in difficulty conceiving.
Treating Low Testosterone in Women
Women who experience low levels of testosterone can explore a variety of treatment options, such as:
Hormone replacement therapy (HRT): This testosterone therapy is prescribed by healthcare providers and comes in the form of topical gels, creams, patches, or injections.
Dehydroepiandrosterone (DHEA) supplements: DHEA is a hormone that stimulates testosterone and other androgens in the body. This testosterone treatment should only be used under the supervision of a healthcare provider as it may have potential side effects and might not be suitable for all women.
Clomiphene citrate: A medication that stimulates the ovaries to produce more testosterone. This treatment is often prescribed to women with PCOS.
Lifestyle changes: Adopting a balanced diet, increasing physical activity, and using stress management techniques are natural ways to increase your testosterone levels.
Management of underlying conditions: If low testosterone is the result of a medical condition, such as PCOS or adrenal disorders, the focus should be on addressing these, which may lead to improved testosterone levels.
Medication adjustments: If low testosterone is being caused by certain medications, your doctor may adjust your dose or suggest alternatives.
Vaginal hormone therapy: Topical hormone therapies can be used by women who experience vaginal dryness and discomfort due to low testosterone levels.
Key Point: How Do Doctors Diagnose Low Testosterone in Women?
Most healthcare providers will be able to diagnose low testosterone levels by using a blood test. However, it’s important to note that hormone levels fluctuate during the menstrual cycle, meaning your blood test results may vary.
There are four types of blood tests your doctor can run to determine if you have low testosterone levels:
-
Total testosterone level: This test measures the overall level of testosterone in the bloodstream.
-
Free testosterone level: Free testosterone is the biologically active form of the hormone that isn’t bound to proteins in the blood. This is usually a more accurate indicator of testosterone levels.
-
Sex hormone-binding globulin (SHBG): This is a protein that binds to testosterone and can affect how much of this hormone the body can use.
-
Dehydroepiandrosterone sulfate (DHEA-S): As mentioned above, DHEA is a precursor to testosterone and can provide your doctor with information about androgen production in your body.
-
Other hormone levels: Additional tests may be used to measure other hormones in your body.
When Should I Seek Medical Help for Low Testosterone Levels?
If you are experiencing any of the symptoms outlined above — especially if they’re affecting your overall quality of life — it’s important that you speak to a healthcare provider.
Low testosterone levels in women could also be an indication of an underlying health condition such as Addison’s disease, which may require specific treatment
