Biologically speaking, testosterone plays a HUGE part in making you a man. It's the hormone that created your male sex organs during fetal development, the hormone that developed your androgenic features during puberty, and the hormone that bodybuilders leverage to increase these androgenic features post-puberty.
Yes, testosterone is pretty powerful stuff, playing a vital role in the human body. It regulates your sex drive, bone mass, muscle mass, fat distribution, strength, and the production of your red blood cells and sperm. This is why we do everything we can to keep it.
Besides low sex drive and erectile dysfunction, suboptimal testosterone can manifest in:
- Diabetes and insulin resistance
- Metabolic dysfunction
- Weight gain
- Chronic inflammation
- Poor exercise recovery
As we get older, the body's natural testosterone production gradually drops. Unfortunately, that's normal human biology — something to just accept with grace. But other factors can accelerate the decrease in testosterone, and these are things we can
control. Certain lifestyles and diets, for example, can diminish testosterone and increase estrogen, the female sex hormone (which could lead to moobs
, or man boobs).
