Marijuana Affects Sperm

The long known myth about sperm being affected by marijuana use has proven to be true!  A study at the University of Sheffield shows that cannabis use can affect the size and shape of sperm.  

Less than four percent of a man's sperm has a normal shape and size.  With that being true, young men that smoke weed can have a significantly harder time fathering offspring.  That may be good news for those not looking to have kids at the moment however, it may hurt your chances in the future.

Scientists still do not fully believe this study to be true.  During research, it was also discovered that there were decreases in sperm normality during the summer months.  Also, hormonal changes and surprisingly the length of day can also affect the quality of a man's sperm.

Something to think about, huh?
