The impact of cannabis on human fertility has emerged as a critical public health concern, particularly as global cannabis consumption has surged by 23% since 2010. With 209 million users worldwide and growing, most being males of reproductive age, understanding cannabis’s effects on fertility has never been more urgent. This increase coincides with a troubling trend – global sperm counts declined by 51.6% from 1973 to 2018, and continue to fall at an accelerating rate.
The convergence of rising cannabis use and declining sperm counts has spurred renewed scientific interest in how cannabis, particularly its primary psychoactive compound THC, affects male fertility. Two landmark studies – Morishima’s groundbreaking 1984 research and Kuzma-Hunt’s comprehensive 2024 analysis – provide crucial insights into the cellular and molecular mechanisms through which cannabis influences reproductive outcomes.
