Androgens in Women: When Testosterone Is Too High — or Too Low

Androgens are often thought of as "male hormones," but they are just as important in women. They influence libido, energy, bone density, muscle mass, mood, and importantly — reproductive function.

In women, testosterone and other androgens must strike a delicate balance. Too much or too little can impact fertility, menstrual regularity, and overall health.

What Are Androgens in Women?

Androgens include:

• Testosterone – regulates libido, ovulation, and energy
• DHEA (dehydroepiandrosterone) – a precursor to testosterone and estrogen
• Androstenedione – another precursor hormone

Produced mainly in:

• Ovaries
• Adrenal glands
• Peripheral tissues (conversion of precursors)

Normal levels support reproductive function; imbalances disrupt cycles and ovulation.

High Androgens: Causes and Consequences

Elevated androgen levels are most commonly seen in:

1. Polycystic Ovary Syndrome (PCOS)

• Most common cause of hyperandrogenism
• Leads to irregular cycles or anovulation
• Symptoms: hirsutism, acne, weight gain, insulin resistance

2. Congenital Adrenal Hyperplasia (CAH)

• Rare genetic disorder affecting adrenal steroid production
• Can cause elevated androgens and fertility challenges

3. Tumors

• Ovarian or adrenal tumors are rare but can dramatically raise androgen levels

Impact on Fertility:

• Disrupts ovulation
• Alters endometrial receptivity
• May increase miscarriage risk
• Impairs egg quality in some cases

Other Symptoms:

• Excess facial/body hair
• Acne
• Thinning scalp hair (female pattern hair loss)
• Mood changes

Low Androgens: An Overlooked Fertility Factor

While high androgens are widely recognized, low androgen levels are less commonly considered — yet they are just as important for reproductive health.

Causes of Low Androgens:

• Premature ovarian insufficiency
• Hypopituitarism or hypothalamic dysfunction
• Chronic illness or stress
• Age-related decline (particularly DHEA)

Impact on Fertility:

• Reduced libido and sexual function
• Poor ovarian response in IVF
• Low energy and reduced bone/muscle health
• Subtle disruption of follicular development

Symptoms of Low Androgens:

• Low libido
• Fatigue
• Muscle weakness
• Mood disturbances

Striking the Right Balance

Optimal reproductive function relies on moderate androgen levels. Both extremes — too high or too low — can impair ovulation, egg quality, and implantation.

• High androgens → anovulation, insulin resistance, endometrial effects
• Low androgens → poor follicular development, low libido, reduced ovarian response

Testing Androgen Levels

Evaluation typically includes:

• Total and free testosterone
• DHEA-S
• Androstenedione
• LH/FSH ratio (often relevant in PCOS)
• SHBG (affects free hormone availability)

Interpretation must be individualized — what's normal for one woman may not be optimal for another.

Management Strategies

High Androgens:

• Lifestyle: weight management, low-glycemic diet, exercise
• Insulin-sensitizing agents (e.g., metformin in PCOS)
• Anti-androgen medications (for symptoms, not always for fertility)
• Ovulation induction with targeted fertility treatments

Low Androgens:

• DHEA supplementation (in select IVF patients)
• Optimize adrenal and ovarian health
• Address chronic stress and metabolic factors

Treatment should always be tailored to reproductive goals and overall health.

The Bigger Picture

Androgen balance is critical for:

• Ovulation and egg quality
• Endometrial receptivity
• Sexual health and libido
• Energy, mood, and bone health

Ignoring subtle androgen imbalances can leave fertility issues unexplained — even when estrogen and progesterone levels appear normal.

The Bottom Line

In women, androgens are not just "male hormones" — they are essential reproductive regulators.

Both high and low levels can disrupt ovulation, reduce fertility, and affect overall well-being. Understanding androgen balance, and treating it appropriately, can make a meaningful difference in reproductive outcomes.

Fertility care is not only about numbers — it's about hormonal harmony.
