Previous Cannabis Use Myth Dispelled?
Once again the legalization and increased research into cannabis use in humans are dispelling previous beliefs. A 2025 paper outlining a study led by Boston University School of Public Health challenges previous assumptions about cannabis use and male fertility. The research analyzed semen samples from 921 men, focusing on metrics like s***m count, concentration, motility, and volume and showed no statistically significant differences were found between cannabis users and non-users in these measures, even among daily users (3.3% of participants) or regular users (22.6%) .
This finding contrasts with earlier studies that suggested cannabis might lower testosterone or s***m quality. The researchers noted inconsistencies in prior work, such as animal studies indicating THC (the psychoactive compound in cannabis) could affect testicular function, but these effects were not observed in their human cohort . They emphasized that while their results add valuable evidence, they do not conclusively resolve the debate.
The study highlights the need for further large-scale, long-term research across diverse populations to better understand cannabis's reproductive health impacts.
