Androgen deprivation therapy (ADT) is the first line treatment for advanced, metastatic, and recurrent prostate cancer due to its ability to dramatically reduce circulating testosterone. Other research has shown that testosterone may exert an antidepressant action by activating androgen receptor MAPK-ERK2 signaling in the hippocampus . Increasing testosterone levels have been found to inhibit hypothalamic GnRH release via classical negative feedback thereby reducing anterior pituitary secretion of LH and FSH and their stimulation of testosterone steroidogenesis . Furthermore, using a logistic regression, this study found that high depression scores were present in 61% of men with hypogonadism compared to only 14% of eugonadal men .
The impact of chronic stress and the subsequent activation of the SNS on testosterone levels is well-documented. In times of stress, the body prioritizes the production of cortisol over testosterone, leading to a decrease in testosterone levels. While cortisol is necessary for our survival, chronic high levels can have detrimental effects on health, including a negative impact on testosterone production. Therefore, it is possible that increasing testosterone levels through the use of testosterone boosters could enhance the body’s "fight or flight" response. While research directly examining the effects of testosterone boosters on the SNS is limited, studies have shown that testosterone can influence sympathetic activity. Testosterone boosters, such as Prime Male, are supplements designed to naturally increase testosterone levels.
The safety of TRT has only been established for management of symptomatic hypogonadism and is recommended by the American Urological Association and Endocrine Society guidelines. The role of sex hormones in headache medicine is an emerging area of interest, though current literature largely focuses on female hormones and their association with migraines. Placebo-controlled trials are necessary to ascertain the role and safety of TRT in men with epilepsy. There is no evidence supporting the role of TRT for management of epilepsy.
However, it is important to note that the use of testosterone boosters should be approached with caution. They typically contain ingredients like D-Aspartic Acid, Vitamin D, and Zinc, which have been shown to support testosterone production. Given the relationship between testosterone and the SNS, it is plausible that testosterone boosters could influence the functioning of the SNS.
This suggests that testosterone and the SNS are closely linked, with testosterone potentially enhancing the body’s "fight or flight" response. There are also evidences against the neuroprotective action of testosterone. Alzheimer's disease (AD), mild cognitive impairment (MCI) or depression. One of the less known testosterone actions is neuroprotection. Testosterone -- the gonadal sex steroid hormone plays an important role in the central nervous system (CNS) development.
Thus, there is no clear role for TRT in the prevention or treatment of MCI or dementia. Similarly, another study with a one-year follow-up reviewed the impact of TRT versus placebo in men with MCI and symptomatic hypogonadism and showed no improvement in cognitive function 47, 48. One study showed no difference in cognitive performance in hypogonadal men with mild cognitive impairment on TRT compared to those on placebo at 12 weeks follow-up. This points to a possible link between androgens and amyloid beta pathway and a possible neuroprotective effect through downregulating the amyloid beta toxicity. Additionally, there is an inverse relation between serum or brain testosterone level and hippocampal volume. A randomized, controlled, double-blind trial conducted in 1989 studied the effects of TRT in 40 men with myotonic dystrophy and ultimately demonstrated increased muscle mass but without positive impact on overall strength . Another study found that androgen supplementation led to muscle growth but worsened motor neuron death and survival.
