Testosterone in Perimenopause and Menopause Info

Understanding Testosterone's Role Testosterone is an important hormone in women, produced mainly by the ovaries and adrenal glands. Fun Fact: we need more testosterone than estrogen. It plays a key role in libido, energy levels, muscle mass, bone health, mood, and cognitive function. During perimenopause (the transition to menopause, often starting in the 40s) and menopause (marked by 12 months without a period), testosterone levels gradually decline, sometimes leading to symptoms that affect quality of life. This decline can begin earlier than estrogen and progesterone drops and continues post-menopause. While not all women experience issues from low testosterone, many do, and therapy may help under

Testosterone levels peak in a woman's 20s and start declining around age 30, with a more noticeable drop during perimenopause and menopause. By menopause, levels can be about a quarter of their peak. This decline is gradual but can contribute to hormonal imbalances, especially alongside falling estrogen and progesterone. Factors like ovarian aging, stress, and medications can accelerate this.

Low testosterone can manifest in various ways, often overlapping with other menopausal symptoms. Common signs include:

- Low libido: Reduced sexual desire, arousal, or pleasure.

- Fatigue and low energy: Feeling constantly tired or lacking stamina.

- Muscle weakness and loss of tone: Decreased strength, muscle mass, or difficulty building muscle.

- Mood changes: Anxiety, irritability, depression, or low mood.

- Cognitive issues: Brain fog, memory loss, or trouble concentrating.

- Other physical symptoms: Weight gain, insomnia, hot flashes, vaginal dryness, joint pains, thinning hair, or bone loss.

These symptoms may not solely be due to low testosterone, so testing is essential.

Testosterone therapy, often as part of hormone replacement therapy (HRT), can address deficiencies and improve several areas:

: Enhanced libido, arousal, orgasm, and reduced distress about sex.

: Increased energy, reduced fatigue, and better overall well-being.

: Improved muscle tone, strength, and bone density. Testosterone is the only hormone that builds bone. Estrogen maintains bone.

: Better mood, reduced anxiety/irritability, improved sleep, and sharper cognitive function.

: Potential anti-inflammatory effects, cardioprotection, neuroprotection, and relief from vulvovaginal symptoms.

Benefits are most evident in postmenopausal women with low libido, but evidence for premenopausal use is limited. Therapy is typically transdermal (gels, creams) for better safety.

Testosterone levels vary by age, lab, and measurement method (total vs. free). For women:

: Total testosterone: 9-55 ng/dL (or 0-55 ng/L in some units).

:Total testosterone: 0-40 ng/L, or often below 30 pg/mL.

Therapy aims to restore levels to the normal physiological range for women, often targeting levels from our 20’s or levels from our 30s. Regular blood tests monitor this;

While generally safe at low doses, testosterone therapy can cause:

: Acne, oily skin, increased facial/body hair (hirsutism), or scalp hair loss.

: Deepening voice (rare, usually reversible at low doses).

: Weight gain, fluid retention, changes in lipid profile (e.g., lower HDL cholesterol), or edema. This is usually only noted initially and levels out over time.

: Mood changes like anxiety, or rare risks if doses are too high (e.g., clitoral enlargement). I have only seen this in supraphysiologic doses in women transitioning.

Side effects are often mild, reversible, and less common with transdermal vs. oral forms. They're higher without concurrent estrogen therapy. Monitoring and dose adjustments minimize risks.
