The effects of cannabis on the hormonal system and male fertility remain controversial within the scientific community. A study conducted by the University of Geneva (UNIGE), in collaboration with the Swiss Center for Applied Human Toxicology (SCAHT), provides a new answer by showing that cannabis use does not reduce testosterone levels in young men and may even increase its testicular synthesis.
However, this increase in hormone levels cannot be directly linked to fertility. These conclusions are based on a detailed analysis of plasma samples from 94 Swiss conscripts. In addition, the researchers identified two new hormonal biomarkers that may help detect regular cannabis use. The findings have been published in Communications Medicine.
Some studies suggest that cannabis may reduce sperm count, concentration, and motility. These effects are believed to be linked to the endocannabinoid system—a network of chemical messengers and receptors in the brain and reproductive organs that interacts with sex hormones. However, the findings of studies conducted so far — particularly regarding the impact of cannabis use on testosterone — have often been contradictory.
