Ep. 39 - Cannabis & Sperm Donors: Just Say No! (Part 4)

Our past several episodes have focused on how cannabis use is harmful across all stages of pregnancy, from the prenatal to the lactation period. However, there is another person in this equation that results in a pregnancy, and until just recently, men have been largely left out of the research regarding the effects of cannabis use in relation to reproduction. That is changing as increased legalization and access to cannabis has researchers examining the effects of its exposure on male reproduction. 

In this episode of CNT, we highlight the adverse effects of cannabis exposure in men that may create long-term genetic changes in their offspring.  From the accumulating evidence, we can state with certainty that men who are interested in contributing to a pregnancy should refrain from cannabis use, as it affects not only sperm cells but can also create harmful DNA alterations that are hereditary.  In other words, men should also just say no if they plan on contributing to a pregnancy.
