Several past studies have highlighted the dramatic effects drug use has on male sperm and this new study published in the journal Human Reproduction was intended to corroborate the previous data. However, there were some major differences that could help bring an end to the debate.
New studies must use new standards to make appropriate correlations regarding drug use
In the new study, different attributes were separated out in order to begin to establish a associations. 1011 men were recruited and factors such as marijuana use, alcohol use, cocaine use, tobacco use, coffee intake, age, body mass, education, race and more were assessed and recorded. When the results came in, a clear distinction between ‘recreational drug users (those who use drugs like cocaine) ande marijuana users was evident, and the results were shocking.
Men who had ever smoked marijuana had significantly higher sperm concentration than men who had never smoked marijuana in unadjusted (Supplementary Table III) and multivariable-adjusted analyses…
Their conclusions showed men with a history of marijuana use had “significantly higher sperm concentration” as opposed to those who had never used marijuana. A quick recheck of methods reaffirmed the results. Is it possible cannabis increases sperm count?
Before you make any inferences, there still is a viable reason men with a history of cannabis use are shown to have higher sperm concentrations. It is commonly accepted that men with higher levels of testosterone have higher sperm concentrations and sperm counts than men with lower testosterone levels. Noted in the article and the study, men who are willing to experiment with cannabis, and other drugs for that matter, may already have a higher testosterone level leading to the higher risk behavior of experimenting with drug use. So before you run off to the dispensary to stock on baby-making strains and infused products, let the research catch up. This is a great baseline so start from and perhaps, with a little luck, it will be quickly acted upon and further researched.
Previous studies have largely focused on recreational drug use as a whole and included cannabis as part of the reasoning for lowered sperm counts. One study conducted on incoming military personnel attributed a 55% decrease in sperm count to recreational drug use which notably included marijuana use. The other ‘recreational drugs’ were not identified or singled out in an effort to create reasonable associations for such a drastic reduction in sperm. As a results of studies like this, the masses have been told smoking marijuana would lower men’s sperm counts and make procreation more difficult for families for years. The reality is, we really do not know much about cannabis use and the effects on fertility and studies like this will help influence others to conduct more research for answers, especially as cannabis use and legalization are spreading world-wide.
