Another flaw with many of these studies is that they do not control for the fact that smoking has massively decreased in Western countries,<ref>https://ncci.canceraustralia.gov.au/prevention/smoking-prevelance/smoking-prevalence-adults</ref> with cigarette consumption peaking in the 1950s and falling to low levels in the modern era.<ref>https://ourworldindata.org/smoking</ref> | Another flaw with many of these studies is that they do not control for the fact that smoking has massively decreased in Western countries,<ref>https://ncci.canceraustralia.gov.au/prevention/smoking-prevelance/smoking-prevalence-adults</ref> with cigarette consumption peaking in the 1950s and falling to low levels in the modern era.<ref>https://ourworldindata.org/smoking</ref> | ||
This is because smoking is correlated with higher free and total serum testosterone levels,<ref>https://pubmed.ncbi.nlm.nih.gov/31528824/</ref> a link that is not known to be casual (it could be due to T being linked to impulsiveness and risk taking etc.), though it likely is to some degree as nicotine and other compounds found in tobacco have moderate anti-aromatase properties.<ref>https://www.researchgate.net/publication/232974519_Potential_Contribution_of_Aromatase_Inhibition_to_the_Effects_of_Nicotine_and_Related_Compounds_on_the_Brain</ref> The inhibition of the aromatase enzyme would lead to increased T levels as the body would tend to compensate for the lower estrogen levels by increasing testosterone production.<ref>https://www.getroman.com/health-guide/anastrozole-improve-testosterone/</ref> | This is important because smoking is correlated with higher free and total serum testosterone levels,<ref>https://pubmed.ncbi.nlm.nih.gov/31528824/</ref> a link that is not known to be casual (it could be due to T being linked to impulsiveness and risk taking etc.), though it likely is to some degree as nicotine and other compounds found in tobacco have moderate anti-aromatase properties.<ref>https://www.researchgate.net/publication/232974519_Potential_Contribution_of_Aromatase_Inhibition_to_the_Effects_of_Nicotine_and_Related_Compounds_on_the_Brain</ref> The inhibition of the aromatase enzyme would lead to increased T levels as the body would tend to compensate for the lower estrogen levels by increasing testosterone production.<ref>https://www.getroman.com/health-guide/anastrozole-improve-testosterone/</ref> | ||
