The signs of low testosterone in women are far more common than most people realise, yet they are routinely dismissed or misattributed to stress, aging, or simply "just being tired." Testosterone is not a male-only hormone. Women produce it too, and when levels drop, the effects ripple across energy, mood, libido, muscle strength, and cognitive clarity. If you have been experiencing unexplained fatigue or a flat feeling that no amount of sleep seems to fix, low testosterone female symptoms could be the missing piece. This guide walks through everything you need to know, including how to recognise women testosterone deficiency and how to boost testosterone naturally in women through evidence-informed lifestyle changes. For a broader foundation, explore The Complete Guide to Female Hormones before diving in.
What Is Testosterone's Role in Women?
Testosterone in women is produced primarily in the ovaries and adrenal glands, and it plays a vital role in energy metabolism, sexual desire, bone density, and muscle maintenance. Though circulating levels are roughly 10 to 20 times lower than in men, the hormone is equally important for female wellbeing and changes meaningfully across the menstrual cycle.
Most people associate testosterone with male biology, but women rely on this androgen for a wide range of functions. In the follicular phase, testosterone rises alongside estrogen, contributing to the boost in motivation and confidence many women notice around ovulation. It also helps maintain bone mineral density, supports red blood cell production, and keeps mood regulated. Understanding this context is essential when interpreting any symptoms that might point toward women testosterone deficiency.
Testosterone also interacts with other androgens. If you want to understand how these hormones connect, the article on Androgens and Your Cycle: The Hidden Driver provides useful background.
What Are the Signs of Low Testosterone in Women?
The most recognised signs of low testosterone in women include persistent fatigue that does not resolve with rest, reduced libido, difficulty building or maintaining muscle, low mood, brain fog, and a general loss of motivation or drive. These symptoms often develop gradually, which is why women testosterone deficiency is so frequently overlooked.
Here is a closer look at the key low testosterone female symptoms to watch for:
Fatigue and Low Energy
This is often the first and most pervasive symptom. Unlike normal tiredness, the fatigue linked to women testosterone deficiency tends to feel heavy and persistent, not lifted by a good night's sleep. It can make even simple tasks feel draining.
Reduced Libido
Testosterone is the primary driver of sexual desire in women. A significant drop in libido, particularly when it feels sudden or out of character, is one of the clearest low testosterone female symptoms. This is distinct from the cyclical shifts in desire most women notice across their cycle.
Loss of Muscle Tone and Strength
Testosterone supports muscle protein synthesis. When levels fall, maintaining muscle becomes harder even with consistent exercise. Women may notice that their body composition changes, with less muscle and more fat accumulation around the abdomen, despite no major change in diet or training.
Brain Fog and Difficulty Concentrating
Cognitive symptoms are among the most underreported signs of low testosterone in women. Difficulty with focus, word retrieval, and mental sharpness can all be connected to declining androgen levels, particularly in perimenopause.
Low Mood and Flat Affect
Testosterone contributes to dopamine signalling, which underpins motivation and reward. Women with women testosterone deficiency often describe a loss of enthusiasm or a flat, joyless quality to their days that does not fully meet the criteria for clinical depression but is genuinely debilitating.
Thinning Hair and Dry Skin
Hair thinning, particularly at the crown, and dry or dull skin can accompany low androgen levels. These changes are subtle at first but tend to become more apparent over time.
"Testosterone in women is like a quiet background hum. When it drops, the music doesn't stop, but everything loses a little richness. My patients describe it as feeling like a dimmer switch has been turned down on their entire life."

What Causes Signs of Low Testosterone in Women?
Common causes of low testosterone in women include natural aging and the menopause transition, surgical removal of the ovaries, use of hormonal contraceptives (particularly combined oral contraceptives), chronic stress, adrenal dysfunction, and hypothalamic amenorrhoea from under-eating or over-exercising. Each of these disrupts the pathways through which testosterone is produced or made available in the body.
The ovaries are the primary source of testosterone in premenopausal women, so any condition that affects ovarian function, including premature ovarian insufficiency, will tend to reduce production. Combined oral contraceptives raise sex hormone-binding globulin (SHBG), a protein that binds testosterone and renders it inactive. This can result in persistently low free testosterone even when total testosterone looks normal on a blood test, which is why testing matters and interpretation requires nuance.
Chronic stress is another significant driver. Elevated cortisol competes with testosterone precursors, particularly pregnenolone and DHEA, diverting them toward cortisol production instead. This is sometimes called the "cortisol steal," and it explains why prolonged stress is so damaging to androgen levels over time.
Adrenal dysfunction and thyroid issues can also suppress testosterone. Research published in the Journal of Clinical Endocrinology and Metabolism confirms that hypothyroidism is associated with reduced androgen levels in women, making thyroid function a key variable to investigate alongside testosterone.
How Is Low Testosterone Diagnosed in Women?
Low testosterone in women is diagnosed through a blood test measuring total testosterone, free testosterone, and sex hormone-binding globulin. Testing should ideally be done in the morning during the follicular phase of the cycle. There is currently no universally agreed clinical threshold for "low" testosterone in women, which makes symptom assessment equally important.
The lack of standardised reference ranges is one of the most frustrating aspects of women testosterone deficiency. Many women are told their levels are "normal" while still experiencing a full picture of low testosterone female symptoms. This is often because the test does not account for free testosterone, which is the bioavailable fraction that actually reaches tissues and receptors.
When speaking to your doctor, it helps to present your symptoms clearly alongside your cycle phase and any relevant history, including contraceptive use. The article on Best Blood Tests for Female Hormones covers exactly what to ask for and how to interpret the results.
"We don't have a validated definition of female androgen deficiency, and that creates a real clinical gap. Women with classic symptoms and low-normal total testosterone often benefit significantly from treatment, yet they're frequently dismissed because their numbers don't cross an arbitrary line."

How Can You Boost Testosterone Naturally in Women?
To boost testosterone naturally, women should prioritise resistance training, adequate protein intake, quality sleep, stress reduction, and specific micronutrients including zinc, vitamin D, and magnesium. Reducing alcohol, addressing under-eating, and managing chronic stress are equally important, as these are among the most common suppressors of natural testosterone production.
Here are the most evidence-supported strategies:
Resistance Training
Lifting weights is one of the most effective natural interventions for androgen support. A study in the Journal of Strength and Conditioning Research found that resistance exercise significantly elevated testosterone levels in women post-workout. Compound movements such as squats, deadlifts, and rows tend to produce the strongest response. Aim for two to three sessions per week.
Prioritise Sleep
The majority of testosterone synthesis occurs during deep sleep. Chronic sleep deprivation suppresses androgen production and raises cortisol, creating a double hit on hormone balance. Seven to nine hours of consistent, quality sleep is non-negotiable when you are trying to boost testosterone naturally as a woman.
Optimise Zinc and Vitamin D
Zinc is directly involved in testosterone synthesis and is one of the most common nutrient deficiencies in women. Foods rich in zinc include oysters, red meat, pumpkin seeds, and legumes. Vitamin D functions as a hormone precursor, and research published in Hormone and Metabolic Research found a direct correlation between vitamin D status and testosterone levels in adults.
Manage Cortisol
Because chronic stress actively suppresses testosterone production, addressing the root causes of cortisol dysregulation is essential. Adaptogens, breathwork, regular movement, and reducing overcommitment all play a role. The relationship between cortisol and androgens is direct and bidirectional.
Eat Enough, Especially Fat and Protein
Testosterone is synthesised from cholesterol, so eating too little fat, particularly among women following very low-calorie or low-fat diets, directly impairs hormone production. Adequate dietary protein also supports the muscle maintenance that testosterone normally facilitates. A diet rich in whole eggs, oily fish, avocado, nuts, and seeds provides the raw materials your body needs.
Reduce Alcohol
Alcohol elevates SHBG and disrupts androgen metabolism. Even moderate drinking can meaningfully reduce free testosterone over time, making it worth reassessing if you are experiencing multiple low testosterone female symptoms.
Key Takeaway
Boosting testosterone naturally in women does not require supplements or prescriptions in most cases. Sleep, strength training, adequate nutrition, and cortisol management address the most common root causes of women testosterone deficiency. Start with the basics before reaching for anything more complex.
Does Low Testosterone Affect Bone Health and Weight?
Yes, significantly. Testosterone contributes to bone mineral density alongside estrogen and progesterone, and women testosterone deficiency in perimenopause and beyond is associated with accelerated bone loss. For women approaching midlife, this makes androgen health as important as estrogen health for long-term skeletal integrity.
Weight changes are also connected. Low testosterone is associated with reduced muscle mass and increased fat storage, particularly visceral fat around the abdomen. This is not simply a cosmetic concern: visceral fat is metabolically active and promotes inflammation, which further disrupts hormone balance in a cycle that can be difficult to break without addressing the underlying androgen deficiency.
