Testosterone is a male hormone, a steroid hormone. There are normal values for testosterone in men and women. An increase in testosterone in men is an increase in male hormones. There are some people who often inject themselves with testosterone in order to increase muscle strength, such as people who work out, resulting in increased testosterone and risk of testicular cancer. High testosterone in women has disease causes, such as peripheral transformation problems, testosterone and estradiol binding globulin reduction, which can increase testosterone in women; ovarian or adrenal sebum overproduction, which leads to high testosterone in women. High testosterone in women is mostly an endocrine disorder. No matter male or female, if testosterone is high, it should be treated actively, and it is not easy to cure when the condition is serious.
