The takeaway
Testosterone is gaining attention as a possible solution for menopause brain fog, but research hasn't established that it improves memory or concentration. That doesn't mean your symptoms aren't real, or that testosterone has been proven ineffective. The evidence is simply too limited. Rather than focusing on one hormone, understanding your broader hormonal health and other factors affecting your concentration is a more useful starting point.
What Happened
Testosterone is increasingly discussed as a possible answer to menopause-related forgetfulness and difficulty concentrating. But the evidence behind that promise remains limited.
As highlighted in an October 30 report by iNews, researchers at University College London examined five studies investigating testosterone and cognition, meaning memory, attention and other thinking abilities.
A combined analysis of three trials involving 244 women found no statistically significant improvement in cognitive performance among those receiving testosterone.
However, the studies were small, relatively short and largely focused on postmenopausal women. They cannot establish whether testosterone might affect brain fog during perimenopause.
The finding is important: researchers have not demonstrated a benefit, but they have not definitively ruled one out either.
What To Actually Do
- If brain fog is affecting your daily life: Notice whether it coincides with disrupted sleep, stress, menstrual changes or other symptoms. These details can help your doctor understand the bigger picture.
- Look beyond testosterone: Estrogen, progesterone and other hormonal changes may be relevant, alongside sleep and overall health. Miror's Hormonal Index offers a broader perspective on hormonal health, rather than focusing on one symptom.
- What you don't need to do: Rush into testosterone therapy or expensive hormone testing because you've become forgetful. If symptoms persist or worsen, speak to a qualified doctor about possible causes.
Good to Know
- Testosterone has a recognized, limited clinical role for certain women experiencing distressing low sexual desire after menopause, not specifically for brain fog.
- The research involved relatively small studies, so larger trials are needed.
- Testosterone treatment requires medical assessment and monitoring. Costs and availability vary, and no testosterone preparation is currently licensed specifically for women in India.

Expert review
The most useful part of this research is that it challenges the assumption that replacing one hormone can resolve a complex midlife symptom. But the absence of evidence is not evidence of absence. We still need stronger research, particularly involving women in perimenopause. Brain fog may reflect several overlapping factors, including hormonal fluctuations, disrupted sleep and stress. The better question is not simply whether testosterone helps, but what is contributing to a particular woman's cognitive symptoms and how those concerns should be assessed.
