Two critical hormones that affect overall health are testosterone and thyroid hormones. In conclusion, testosterone and thyroid hormones are both essential hormones that play vital roles in the human body. In the case of hypothyroidism, BHRT can help restore hormonal balance by replacing the hormones your body is missing. If you want to support healthy testosterone production, you also need to focus on your thyroid hormones.
In general, androgens such as testosterone promote protein synthesis and thus growth of tissues with androgen receptors. As the metabolism of testosterone in males is more pronounced, the daily production is about 20 times greater in men. In humans and most other vertebrates, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. Testosterone is a steroid hormone from the androstane class containing a ketone and a hydroxyl group at positions three and seventeen respectively.

Cortisol levels tend to rise with age, particularly in individuals with histories of chronic stress, and the hippocampus is one of the brain structures most vulnerable to the neurotoxic effects of persistently elevated cortisol. While it isn’t a sex hormone, its trajectory across the lifespan has significant implications for how the brain ages. Cortisol deserves its own prominent place in any discussion of hormones and cognitive aging. This is genuinely good news, because unlike the calendar, hormonal health is a terrain you can meaningfully influence. No, you cannot take testosterone with thyroid medication. Patients with hyperthyroidism may take anti-thyroid medications, beta-blockers, and surgery in some extreme cases .
For instance, if you have hypothyroidism (an underactive thyroid), your metabolism may slow down, leading to fatigue and weight gain. If your thyroid is not functioning properly, it can limit the benefits of TRT, making it harder to achieve wellness goals. This is why it’s important to work with a doctor who can interpret your results in the context of your symptoms, medical history, and overall health. Without testing, it’s impossible to know which hormone—or both—is causing your symptoms.
Used thoughtfully alongside the lifestyle foundations, these can meaningfully support the brain through hormonal transitions. Lion’s mane mushroom supports nerve growth factor production relevant to maintaining the neural plasticity that hormonal decline tends to erode. Zinc and magnesium support testosterone synthesis and cortisol regulation respectively. Chronic psychological stress accelerates hormonal dysregulation across the board.
An additional 40% of testosterone is metabolized in equal proportions into the 17-ketosteroids androsterone and etiocholanolone via the combined actions of 5α- and 5β-reductases, 3α-hydroxysteroid dehydrogenase, and 17β-HSD, in that order. Approximately 50% of testosterone is metabolized via conjugation into testosterone glucuronide and to a lesser extent testosterone sulfate by glucuronosyltransferases and sulfotransferases, respectively. The plasma protein binding of testosterone is 98.0 to 98.5%, with 1.5 to 2.0% free or unbound. The amount of testosterone synthesized is regulated by the hypothalamic–pituitary–testicular axis (Figure 2). In addition, the amount of testosterone produced by existing Leydig cells is under the control of LH, which regulates the expression of 17β-hydroxysteroid dehydrogenase. The number of Leydig cells in turn is regulated by luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The male generative glands also contain Sertoli cells, which require testosterone for spermatogenesis.
