Those who admitted to regularly smoking pot had a sperm count that was 29 percent lower than those who reported lighter use or didnât smoke at all. Meanwhile, men who used other recreational drugs alongside marijuana had sperm counts reduced by 55 percent and sperm concentrations reduced by 52 percent. Pot smokers were also found to have higher levels of testosterone within the same range as cigarette smokers.
Researchers found that the men with fertility problems who took 5 mg of folic acid a day and 66 mg of zinc sulfate a day for 26 weeks had a 74% increase in total normal sperm count and a minor (4%) increase in abnormal sperm count. No significant increases were found among the healthy men's sperm counts. The study author says that's most likely due to the greater variability in sperm count in these men compared with the men with infertility. When either zinc or folic acid was taken alone, there was no significant effect on sperm production.
