Yes, being hairy is directly related to testosterone, specifically how hair follicles respond to androgens like testosterone and its derivative, dihydrotestosterone (DHT). These hormones convert vellus hair (fine, light) into terminal hair (thick, dark) on the face, chest, and body. However, genetics determine the sensitivity of follicles to these hormones.
Like so many things, it comes down to a mixture of genetics and hormones. We know that at least some of the genes for hairiness are carried on the X chromosome – and the way these genes are expressed varies between different men and ethnic groups – but hairiness also correlates with high testosterone levels.
Is body hair a sign of high testosterone? Testosterone can cause hair growth but it's not always a sign of high testosterone levels.
Increased body hair—particularly on the chest, back, arms, legs, and buttocks—is extremely common for those on testosterone replacement therapy. Even if you already have hair on those areas, the texture is expected to become more coarse, thick, and dark.
Androgens are male sex hormones, including testosterone, which are responsible for masculine characteristics such as facial hair and coarse body hair. A woman's ovaries and adrenal glands naturally make a small amount of androgens.
Rising levels of androgens during puberty cause vellus hair to transform into terminal hair over many areas of the body. The sequence of appearance of terminal hair reflects the level of androgen sensitivity, with pubic hair being the first to appear due to the area's special sensitivity to androgen.
With hirsutism, extra hair growth often happens due to excess male hormones called androgens. The main androgen involved is testosterone. Self-care methods may be useful for removing unwanted hair. And medical treatment is available for those who wish to treat hirsutism.
Other signs of excess testosterone include increased body hair, headaches, high blood pressure, excess libido, infertility, insomnia, mood swings, urine problems, ankle swelling, or unexplained weight gain.
Testosterone promotes body hair growth in men. As a result, one common symptom of low testosterone is a loss of body hair. You may notice thinning of your armpit or pubic hair. Many men find the change is most noticeable in their beard because they don't have to shave as often.
Well-rounded diets full of healthy fats, proteins, and nutrient-dense fruits and vegetables support healthy testosterone production. Foods that have been linked to increased testosterone include onions, oysters, fatty fish (which contains healthy omega-3 fats), and extra virgin olive oil.
As men age, we produce more 5- alpha reductase, which converts more of our testosterone into dht making us hairier. The reduction in testosterone level by conversion makes it more difficult to build muscle too. Incidentally, DHT also regulates the prostate, and too much can cause unhealthy enlargement.
Increased Body Fat
Men with low testosterone levels may experience increased body fat, particularly in the belly area. This can affect a man's physical appearance and increase his risk of developing health conditions such as heart disease.
Hair growth and size is modulated by hormones, in particular androgens like testosterone, which kick in during puberty. As men generally have higher levels of testosterone than women they tend to have more terminal hair.
The researchers took saliva samples from the men to measure hormone levels of testosterone and cortisol. Women who were at the most fertile stage of their menstrual cycles preferred the smell of men with higher testosterone, rating these "manly" shirts as the most pleasant and sexiest, results showed.
Men with body hair may feel more confident and desirable, especially among partners who appreciate natural body features. Body hair can also serve as a protective barrier for the skin, helping to prevent chafing, skin irritation and reducing the risk of skin infections caused by friction during sexual activities.
Although vellus hair is already present in the area in childhood, chest hair is the terminal hair that develops as an effect of rising levels of androgens (primarily testosterone and its derivatives) due to puberty. Different from the head hair, it is therefore a secondary sexual characteristic.
Exercise. A combination of aerobic (increase in heart rate) and resistance (weightlifting) training has been found to increase the production of testosterone. This also helps prevent the most common diseases that men are most likely to die from, heart disease and cancer.
High free testosterone can affect hair growth, mood, skin health, and fertility. Learn its causes, symptoms, and what to do about it.
To many, urine smells like urine and vanilla smells like vanilla. But androstenone, a derivative of testosterone that is a potent ingredient in male body odor, can smell like either - depending on your genes.
Testosterone hormone levels are important to normal male sexual development and functions. During puberty (in the teen years), testosterone helps boys develop male features like body and facial hair, deeper voice, and muscle strength. Men need testosterone to make sperm.

Causes of hirsutism
Hirsutism is usually linked to changes in androgen levels ("male" hormones). It can happen if the level of these hormones increases or if your body becomes more sensitive to them. The most common cause is polycystic ovary syndrome (PCOS).
Hair follicles – the skin organ responsible for hair growth – contain stem cells that constantly divide, they are the driving force behind new hair growth.
