Testosterone is one of the most critical chemical substances in the body. Typically, the element is the main component in various body functions, and its absence can have far-reaching consequences. It is the critical sex hormone in males, but females have a small portion of it in their body...
Endogenous testosterone levels correlated positively with amygdala reactivity across the young and middle-aged women. The middle-aged women received a single nasal dose of testosterone in a double-blind, placebo- controlled, crossover manner, which rapidly increased amygdala reactivity to a level ...

By using quantitative PCR (qPCR), we also found that higher levels of testosterone may lead to an increase in rhodopsin-like 2 (rh2) and a decrease in long-wavelength sensitive (lws) gene expression in males, a pattern which was also observed in wild males undergoing maturation as they ...
