Remember that this was done back in the 90s when they were looking for anything
to bash cannabis about, but somehow this little gem sneaked out!
Effects of chronic marijuana use on testosterone, luteinizing hormone, follicle stimulating hormone, prolactin and cortisol in men and women. (abst - 1991) Effects of chronic marijuana use on testosterone, ... [Drug Alcohol Depend. 1991] - PubMed resultTo investigate possible effects of chronic marijuana use on reproductive and stress hormones, we assayed testosterone, luteinizing hormone, follicle stimulating hormone, prolactin, and cortisol in 93 men and 56 women with a mean (+/- S.E.) age of 23.5 +/- 0.4 years. Hormone values were compared among groups of subjects stratified according to frequency of marijuana use (frequent, moderate and infrequent; N = 27, 18, and 30, respectively) and non-using controls (N = 74). Chronic marijuana use showed no significant effect on hormone concentrations in either men or women.
And then there is the "man-boobs" myth which would be caused by a drop in testosterone- the US Army had something to say about that WAY back in the 70s! The title says enough!
Gynecomastia and cannabis smoking: A nonassociation among US Army soldiers

So dudes, I think I'd take the US Army's word on that subject- they had a LOT of soldiers back in the 70s!
And of course there is good old Arnold! Just how many times have you seen that picture of him toking? Didn't seem to do him much harm! He was hardly a "girly-man"! lol (FYI - Arnie and I share a birthday!- July 30, 1947)
