The easiest way to lower testosterone levels in the short term is to have sex with someone who is nice and sympathetic to you, in a comfortable environment for both of you.
In the long term, you can disfigure yourself in a variety of ways - from alcoholism to clandestine hormonal experiments and castration. But why?
Yes, of course.
1) We run to the nearest store.
2) We buy delicious beer and the most fatty and salty croutons on a snack.
3) We sit on a cozy sofa.
4) Turn off the clinging mobile phone.
5) We start an exciting show-movie-serial-marathon.
We repeat the algorithm of this pleasant suppression of masculinity until the desired result is obtained!
Note: Beer suppresses testosterone production and increases estrogen levels, and too salty and fatty foods actively contribute to the former paragraph.
Lack of physical activity also dramatically lowers the production of hormones, including testosterone.
