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.
