Dear mstang,

Yes, smoking weed could potentially lower a guy's sperm count. The primary active ingredient in marijuana is called THC (delta-9-tetrahydorcannabinol). Marijuana, like alcohol, can reduce sexual inhibitions. However, it may also reduce sex drive. This is because THC lowers testosterone levels, the hormone that is related to the sex drive in both women and men. In men, lower testosterone levels may decrease sperm count and muscle mass, as well.

Hope this information helps!

Take care,
