Testosterone is the most common and most active androgen, produced by the testicles of men. Hirsutism in men is often linked to high levels of testosterone and androgen hormones that lead to the growth of body hair. Factors such as genetics and hair follicle sensitivity also play an important role.
Additionally, the study by Simonsen et al. (2016) indicate that the degree of hirsutism in men is largely related to genetic factors and the sensitivity of hair follicles to androgens, rather than to overall testosterone levels. This means that hirsutism is not a reliable sign of whether a man is sexually strong or weak.
Besides, research by Nieschlag and Behre (2012) shows that men’s physiological health depends on the balance between hormones and other factors, such as nutrition and general health status. .
Therefore, relying solely on the degree of hirsutism to assess physiology is not enough and may not be accurate.
