Testosterone Therapy for Women: Unpacking the Clinical Evidence, Benefits, and Risks

Written by Adam Maggio | Medically reviewed by Dr. Mitchell Ross, MD, ABAARM

Testosterone therapy for women is primarily evidence-based for hypoactive sexual desire disorder (HSDD) in postmenopausal women, with other benefits less conclusive. It involves careful off-label dosing and monitoring to avoid androgenic side effects.

# Testosterone Therapy for Women: Unpacking the Clinical Evidence, Benefits, and Risks

Testosterone, often perceived as a primarily male hormone, plays a crucial and often overlooked role in female physiology, influencing sexual desire, bone health, muscle strength, cognitive function, and mood. Despite its importance, no testosterone formulations are currently approved by regulatory agencies like the FDA specifically for women in the United States. Consequently, testosterone therapy for women is typically prescribed off-label, utilizing formulations approved for men at significantly lower doses, or through compounded preparations. The evidence, while growing, primarily supports its use for a specific indication: hypoactive sexual desire disorder (HSDD) in postmenopausal women.

The Evidence for Sexual Function: Addressing Hypoactive Sexual Desire Disorder

The most robust evidence for testosterone therapy in women centers on its efficacy in treating hypoactive sexual desire disorder (HSDD), characterized by a persistent or recurrent deficiency or absence of sexual fantasies and desire for sexual activity, causing personal distress. Multiple randomized controlled trials (RCTs) have demonstrated that low-dose testosterone therapy can significantly improve sexual function, including desire, arousal, orgasm, and overall sexual satisfaction, in postmenopausal women diagnosed with HSDD [1, 2].

A 2014 systematic review and meta-analysis of 35 randomized trials (n=5053) found that testosterone use was associated with statistically significant improvement in various domains of sexual function and personal distress in postmenopausal women [2]. Similarly, a 2020 study suggested that adding testosterone to estrogen replacement therapy could improve sexual function and overall well-being in postmenopausal individuals [1]. These improvements are typically observed with doses that maintain testosterone levels within the premenopausal female physiological range.

Beyond Libido: Other Potential Benefits and the Gaps in Evidence

While the impact on sexual function is well-established, evidence for other potential benefits of testosterone therapy in women is less conclusive. Some women report improvements in mood, energy levels, cognitive function, and muscle strength. However, a global position statement on testosterone therapy for women concluded that there are insufficient data to support its use for the treatment of any other symptom or clinical condition, or for disease prevention [3].

Research is ongoing to explore the effects of testosterone supplementation on bone density, body composition, anemia, and overall quality of life. For instance, the 2014 meta-analysis noted no significant effect on anthropometric measures and bone density, though it did find an association with changes in lipid profiles (reduction in total cholesterol, triglycerides, and HDL, and an increase in LDL) [2]. It is crucial for clinicians and patients to understand that while anecdotal reports of broader benefits exist, they are not consistently supported by high-quality clinical evidence.

Dosing and Administration: Navigating Off-Label Use

Given the lack of FDA-approved female-specific formulations, clinicians must exercise careful judgment when prescribing testosterone. The goal is to achieve physiological testosterone levels typical of premenopausal women, which are significantly lower than those in men. Common administration methods include:

Male Topical Solutions: Gels and solutions designed for men are often prescribed at a fraction of the male dose (e.g., one-tenth). Patients must be meticulously instructed on precise dosing to avoid supraphysiological levels.

Compounded Gels and Creams: These custom-prepared formulations allow for precise, low-dose delivery. However, compounded drugs are not FDA-regulated, raising concerns about consistency in sterility, dosing, and quality.

Pellets: Subcutaneous pellets that slowly release testosterone over several months are available but are considered controversial due to concerns about inconsistent dosing and the inability to adjust or remove the medication if side effects occur [3].

Acne and oily skin

Increased facial and body hair growth (hirsutism)

Changes in body odor

Excessive sweating

Scalp hair thinning (androgenic alopecia)

Deepening of the voice

Clitoral enlargement

Menstrual irregularities or cessation

Mood changes, including increased aggression or irritability

Contraindications for testosterone therapy include pregnancy, breastfeeding, active liver disease, hormone-sensitive conditions (e.g., certain cancers), uncontrolled hyperlipidemia, and severe acne. Combining testosterone with other androgen-boosting supplements, such as DHEA, can also increase the risk of side effects [3]. While some short-term studies show no increased risk of cardiovascular disease and even hint at a potential protective effect against breast cancer, this evidence is still evolving and requires further long-term investigation [3].

Clinical Considerations and Guidelines

Given the complexities, individualized care and shared decision-making are paramount. Before initiating therapy, clinicians should thoroughly evaluate the patient's symptoms, rule out other causes for low libido, and measure baseline testosterone levels. If no improvement is observed after approximately six months of therapy, discontinuation should be considered [3].

Professional guidelines, such as those from the International Menopause Society and The Endocrine Society, emphasize that the only evidence-based indication for testosterone therapy in women is for postmenopausal women with HSDD. They also highlight the need for careful patient selection, appropriate dosing, and regular monitoring to ensure safety and efficacy [3].

Practical Takeaways

For practitioners, understanding the nuanced role of testosterone in women's health is key. While it is not a panacea for all menopausal symptoms, it offers a valuable therapeutic option for postmenopausal women experiencing distressing HSDD. For patients, open communication with a knowledgeable healthcare provider is essential to weigh the potential benefits against the risks, understand the off-label nature of treatment, and commit to ongoing monitoring. The field continues to evolve, and future research will undoubtedly provide more clarity on the long-term safety and broader applications of testosterone therapy in women.
