What is testosterone known as?

Testosterone is primarily known as the male sex hormone. It plays a crucial role in the development of male reproductive tissues such as the testes and prostate, as well as promoting secondary sexual characteristics like increased muscle and bone mass, and the growth of body hair. While testosterone is present in both males and females, it is significantly higher in males, directly influencing male sexual function and overall health.

The option identifying testosterone as a female hormone is incorrect because, while females do produce testosterone, the levels and functions differ greatly compared to males. The description of testosterone as a growth hormone is also misleading; growth hormones primarily regulate growth and metabolism, while testosterone specifically affects sexual development and secondary sexual characteristics. Lastly, the classification of testosterone as an immune hormone is not accurate, as its primary roles are related to sexual characteristics and reproductive health rather than immune system modulation.
