Indeed. A colleague of mine is a urologist and treats his male low testosterone patients with TRT. Low T readings in men typically = low sex drive. But this is not always the case as he told me that he had a patient with low t-levels but had no problem performing in bed.
That said, though the normal T-levels are calculated based the current bell curve, and if we look at the data over the past 100 years the average level of testosterone in men has been dropping consistently over the generations. Some say it's the plastic that has gotten in the food system, others speculate that it's more sinister poisoning of the food chain to make the male populous weak willed and docile in order to implement a stronger dystopia. Whatever the case, testosterone is what gives a man the initiative to get out of bed with energy, creativity, and the willingness to think for himself and fight for what he believes in.
Our genes are made to survive and thrive in a very different environment. We made to live in small groups, with changing sex partners and the whole group cares for the infants. There is great book about how women and babys shaped out higher brainfuntions, if anybody interested i can look it up Small family is already a handicap. The poor diet we have, and cigarettes, nuclear bomb test radiation bla bla bla. we made to live in the tropics, the fruit and variety of it is lacking here. And the sun not being strong most time of the year. I have lived for about 5 years in the tropics, not that it helped my depression. I think I learned my anxiety and fear in childhood from my small family, of course parents also victims.But maybe take a distance and forget about them, get some space between them and you, if you can. My Dad, i still like him, but keep a really big distance, he feels like poision to me.
Lastly Sperm count down dramatically. If we would be breeding bulls we would have been shot right away :)
I still think humans will never be able to understand the body, emotions, consciousness they dont have a clue what it is. To experiment with the body in all kinds of ways, like we did it in nature and the outside world will be as f.....ked up as before.
