What Effect Does Testosterone Have on the Body

Your Guide to What Testosterone Is and What It Does for Your Body

The control group was advised to walk for 30 min three times a week on alternate days for 16 weeks along with a standard dietary plan. In this protocol, different types of exercises, resistance, endurance, and balance, were integrated with proper warm-ups, cool-downs, and rest intervals, which required minimal setup (with only handheld dumbbells), as shown in Table 1. Testosterone is the main androgen (sex hormone) in men and normal levels are needed for physical and mental health. Some females with low testosterone levels might have loss of libido. You may have a greater drop in your testosterone levels if you have long-term medical conditions or if you are living with obesity. If low testosterone is a problem for you, you may want to speak to your doctor about whether it is simply because you are getting older or if there is another cause. Healthy older males may have lower testosterone levels due to the ageing process itself.

A low T test result in an adult man could mean the pituitary gland isn’t working properly. But a young teen with low testosterone levels might be experiencing delayed puberty. Testosterone therapy is approved for the treatment of delayed male puberty and abnormally low production of testosterone secondary to malfunction of the testes, pituitary or hypothalamus. Some men who have a testosterone deficiency have symptoms or conditions related to their low testosterone that will improve when they take testosterone replacement. For example, a man with osteoporosis and low testosterone can increase bone strength and reduce his fracture risk with testosterone replacement.

In this account, ‘T’ becomes the potent, hormonal essence of competitive, risk-taking masculinity. Sex drive is a nonclinical term that means enthusiasm or interest in sexual activity. The presence of it (or lack thereof) can indicate the state of your mental and physical functioning.

“This is part of trying to understand the underlying mechanisms of the immune system.” Dr. Reina-Campos is looking forward to working closely with collaborators, here in San Diego and across the country, to understand how to increase testosterone in men [speech-language-therapy.com] skyrocketing estrogen levels during pregnancy affect T-cell activity in mammary tissue. Not all species have evolved ‘traditional’ sex roles; environment and culture shape human behaviour; and not all men behave in stereotypically masculine ways.

An important takeaway of this diversity of sex roles across species is that we need to be cautious when generalising findings to humans. Every species has its own evolutionary history when it comes to solving the problem of reproduction, and our own evolutionary pathway is a unique one – not least the cumulative culture and social learning I mentioned before. On my account, cultural norms don’t just ‘dial up or dial down’ evolved traits. Let me recap what I understand your position, and the ‘sensible’ T-Rex approach, to be. Stronger sexual selection on males gave rise to masculine physical and psychological traits that facilitate male competition for mates, status and resources. Testosterone ties all this together, making it ‘the hormone that dominates and divides us’, as you’ve written in your 2021 book.

It’s natural for testosterone levels to vary depending on your age and overall health. If they’re consistently high or low, you may experience unpleasant symptoms worth discussing with your provider. If any of these organs — your hypothalamus, pituitary gland or gonads — aren’t working normally, that can cause abnormal testosterone levels. As testosterone in your blood increases, it suppresses the production of gonadotropin-releasing hormone, which helps maintain normal levels of testosterone. Your doctor can check your testosterone levels with a simple blood test. Testosterone therapy is available to treat men with low levels of testosterone.

Free testosterone (the active form) also matters, as does the patient’s overall health picture. It is important to note that testosterone production is a complex process, and the factors that affect it can be interrelated. Suppose you are experiencing low testosterone symptoms, such as decreased libido, fatigue, and muscle weakness. In that case, speaking with a healthcare provider to determine the underlying cause and explore treatment options is important.

These alternative and natural treatments aren’t proven to be more, or as, effective as traditional testosterone therapy. Some may also interact with any medications you may be taking and cause unintended side effects. Research shows that bone density increases with testosterone treatment as long as the dose is high enough. Clinical trials on the effect of testosterone on bone density found increases in spinal and hip bone density.

Carole says that testosterone ‘drives higher rates of aggressive competition in male mammals’ – including humans. As she puts it, sex differences ‘in traits like aggression (or anything else), originate in our differences in inherited biology’. Yet, according to her, this causally potent and ubiquitous hormonal force leaves only some men with a predisposition to aggression (setting aside whether or not it is expressed). For example, research on mice clearly shows testosterone’s causal role in male aggression – it increases at puberty, castration reduces it, and injections restore it.

If you consider your libido levels too low or too high, treatments are available. If a doctor diagnoses a testosterone deficiency, they may suggest a course of testosterone replacement therapy. This should only be done with the guidance of a physician as it can lead to dangerous health issues if done incorrectly.
