Regular cannabis use negatively affects sperm quality, count, and motility.

Scientific research generally agrees that frequent cannabis use can alter sperm vitality. A systematic review published in the Journal of Urology by the team of Rajanahally shows that cannabis is strongly associated with a decrease in sperm count, motility, and morphology. Furthermore, a large observational study conducted by Gundersen and colleagues on more than 1,200 young men revealed an approximately 30% decrease in sperm concentration among regular users. These observations are explained by the presence of receptors sensitive to the plant's active compounds directly on reproductive cells. However, recent prospective data, such as the PRESTO study from Boston University, suggest that light or occasional consumption does not systematically alter these parameters critically in all individuals. Although the link between cannabis and decreased sperm quality is well-documented by these observations, direct evidence of a systematic impact on natural conception remains partial.
