Introduction
Testosterone therapy in women has gained attention primarily for its potential role in treating female sexual dysfunction, particularly in postmenopausal women. The clinical implications and safety of testosterone supplementation remain subjects of ongoing research and debate.
Indications for Testosterone Therapy in Women
Female Sexual Dysfunction: The primary indication for testosterone therapy in women is the treatment of low sexual desire associated with personal distress, particularly in postmenopausal women. This is supported by clinical trials demonstrating improvements in sexual function with testosterone supplementation 1.
Physiological Role: Testosterone plays a crucial role in women’s health, influencing sexual desire, bone density, and overall well-being. However, the physiological changes during menopause complicate the understanding of testosterone’s role 2.
Efficacy of Testosterone Therapy
Clinical Trials: A systematic review of randomized controlled trials indicates that testosterone therapy significantly improves various aspects of sexual function, including sexual desire, arousal, and satisfaction 3. For instance, testosterone administration has shown a mean difference of 0.85 in satisfactory sexual event frequency compared to placebo 3.
Safety Profile: While testosterone therapy can enhance sexual function, concerns regarding its long-term safety profile persist. Some studies report adverse effects such as increased LDL cholesterol and acne, particularly with oral formulations 3. Non-oral routes, such as transdermal applications, are preferred due to a more favorable lipid profile 3.
Controversies and Considerations
Regulatory Status: Currently, no testosterone formulations are approved for women by regulatory agencies in the United States and many other countries, leading to off-label use of male formulations 4.
Guidelines and Recommendations: The Brazilian Society of Endocrinology and Metabolism suggests that testosterone therapy may be considered when other treatments fail, emphasizing the need for thorough discussions regarding risks and benefits with patients 4.
Conclusion
Testosterone therapy presents a potential treatment option for postmenopausal women experiencing low sexual desire. However, the lack of approved formulations and the need for further research into long-term safety and efficacy necessitate careful consideration and patient-specific discussions before initiating therapy.

Safety Concerns of Testosterone Therapy in Women:
Unregulated Prescribing: There is a risk of unregulated and dangerous prescribing practices by healthcare professionals due to a lack of understanding of testosterone as a normal female hormone, leading to potential adverse effects 1.
Adverse Events: Testosterone therapy can lead to supraphysiological concentrations, which may expose women to adverse events. It is crucial to approximate physiological testosterone levels found in premenopausal women 2.
Increased LDL Cholesterol: Oral administration of testosterone has been associated with a significant rise in LDL cholesterol, while non-oral routes (e.g., transdermal) do not exhibit this effect 3.
Dermatological Effects: Testosterone treatment is associated with a higher likelihood of reporting acne and hair growth, although no serious adverse events were recorded 3.
Effectiveness of Testosterone Therapy for Women:
Improvement in Sexual Function: Testosterone therapy has been shown to significantly increase sexual function in postmenopausal women with low sexual desire causing distress, with improvements in satisfactory sexual event frequency, sexual desire, and pleasure 3.
Short-term Efficacy: Short-term treatment periods have demonstrated effectiveness and safety in women with hypoactive sexual desire disorder 2.
Preferred Administration Routes: Non-oral administration (e.g., transdermal) is preferred due to a neutral lipid profile and fewer adverse effects compared to oral administration 3.
