The testosterone hormone plays a role in both men’s and women’s reproductive health. People often think of testosterone as a male hormone that is produced in the testes. However, girls and women also produce a small amount in the ovaries, which is necessary to support fertility and reproduction. In both men and women testosterone also supports energy levels, brain function, libido, and sexual function.
Studies have shown that on a global level, T levels are decreasing, and many people are not even aware of it happening.
