It’s worth noting that hormonal health is just one aspect of overall brain health. They can perform blood tests to check your hormone levels and recommend appropriate interventions if necessary. Don’t forget about sleep – poor sleep can significantly impact hormone levels.
It is hypothesized that loss of function of ARs located at spinal motor neurons, skeletal muscles, and certain cranial nerves increases axonal vulnerability to various insults, contributing to disease pathogenesis . Spinal and bulbar muscular atrophy (SBMA), also known as Kennedy disease, is an X-linked neuromuscular disease characterized by loss of lower motor neurons located in the brainstem and spinal cord. The specific relationship between androgens and hemorrhagic stroke remains under-investigated. Thus, the direct relation between androgen level and homocysteine may act as a potential mechanism for increased cardiovascular events through accelerated atherosclerosis and thromboembolism 18, 19. Dose-dependent effects of testosterone and association with ischemic stroke have been established.
Another advantage of animal experiments is the possibility to surgically localize the administration of testosterone into specific brain structures, which is ethically not possible in humans. But whether the potential is used depends on other factors including environment and timing and form of learning. However, in male deer mice it has been shown that aging but not testosterone affects memory (Perrot-Sinal et al., 1998). This indicates that the effect of testosterone on memory is mediated by estradiol and the effect of aromatase which converts testosterone to estradiol.
In birds, evidence exists for a low testosterone period needed during the development of brain functions such as vocal memory (Korsia and Bottjer, 1991). A smaller, but longer study on postmenopausal women showed the complete opposite—improvement of verbal memory after testosterone treatment (Davison et al., 2011). A relatively high dose of testosterone had no effect on memory or other analyzed behavioral measures in postmenopausal women in a well-designed and large study (Kocoska-Maras et al., 2011).
However, the precise role of androgens in the pathogenesis of these disorders and their potential use in treatment remains largely unexplored . This male predominance, particularly among those with testosterone deficiency, has sparked research into the potential role of androgens in PD pathogenesis and as a therapeutic target. An epidemiological study evaluating the causal relationship between androgen and AD noted a high risk of AD with low androgen levels in men, while no effects were observed in women 43–45. A deeper understanding of the mechanisms involved in neuroplasticity could guide therapeutic interventions with androgens such as testosterone replacement therapy (TRT) in neurological recovery in neurodegenerative diseases. We examine the role of physiologically derived androgens and androgenic supplements in neurodevelopment and neuroplasticity and delve into the involvement of androgen pathways in the pathogenesis of various neurological disorders.

In gifted children, a negative correlation between salivary testosterone and spatial abilities was found (Ostatnikova et al., 1996). The size of the corpus callosum seems to add complexity in the relationship between spatial abilities and testosterone (Karadi et al., 2006). Prenatal testosterone and its proxy—the finger length ratio (second to fourth digit) seem to have a stronger association with figure-disembedding and targeting, as additional spatial abilities (Falter et al., 2006). However, it is not only the actual concentration of testosterone that is studied in relation to spatial performance. Some studies have found a positive relationship between testosterone and mental rotation in men (Silverman et al., 1999). During the productive ages and even in early adulthood, men generally outperform women in spatial abilities (Linn and Petersen, 1985). Selected animal studies analyzing the relationship between testosterone and depression.
