Does that alone explain a 50% drop in the average testosterone level and 50% drop in the average sperm count level over the past 50 years?
In a way, I think it does, yes.
Obviously, environemental factors play a big role in the drop of testosterone levels in men ( mainly endocrine perturbators.)
But I think we ignore the many
psychogenic factors that play a big role in today's loss of men's masculinity.
The brain wiring of first world men is VERY different from what it was 50 years ago.
Nowadays, your brain is conditioned to react differently to external stimuli.
This phenomenon is partly due to the comfortable/spoiled lifestyle of today - times have become easier as many goods/machines/services replaced a lot of the things our pops used to do themselves. Brain chemistry adapted to this raise of standards of living.
Also, people today have access to unlimited sources of enjoyement, which severly disturbs, impacts their dopaminergic system.
Imagine it like a dopamine wave pool ( I stole that one from Dr. Kyle Gillett) - there are natural ups and downs of your dopamine levels/motivation ( the pursuit of the reward/ the ability to focuse our attention on outward goals — the things we want)
In the wave pool, depending on how high the peak is, you often habe a deeper throve, so you do not want too high of a peak. Most importantly, if your peak is extremely high ( from substance abuse for ex), you lose almost all the water in the wave pool, and then when you crash, not only is the throve low, you have less dopamine in the pool to begin with.
Dopamine receptors are extremely sensitive, meaning the depth of the pool can change really quickly, so you wanna have that happy medium where your are fairly near the top but not so near the top that the depth of the pool is going to go down.
At the same time, your role and duties as a man are decreased and discouraged. A strong, unhealthy emphasize is put on your emotions. Repeating relentlessly that your do have FEELINGS and that they matter ! This leaves the door open to many "imaginary" mental illnesses, excuses and victimization, instead of the masculine concepts of accountability and responsibility.
Combine all these factors tohether and you get big fat, entitled crybabies with absolutely zero emotional or physical RESILIENCE.
Male drive, motivation, positive aggression, physicality and dominance are all destroyed with psycho-social tactical nukes.
Im no endocrinologist, but I cant imagine it has no influence on our hormonal profile.
Again, first-fucking-world problems
Just my opinion
