Association of Marijuana Use and the Incidence of Testicular Germ Cell Tumors |
Mar 2009 |

Negative
We observed an association between marijuana use and occurrence of nonseminoma germ cell tumors of the testis. Additional studies of TGCTs are needed to test this hypothesis, including molecular analyses of cannabinoid receptors and endocannabinoid signaling that may provide clues to biologic mechanisms.

Cannabis use and incidence of testicular cancer: a 42-year follow-up of Swedish men between 1970 and 2011 |
Feb 2018 |
|
Neutral
No evidence was found of a significant relation between lifetime ever cannabis use and the subsequent development of testicular cancer [n = 45 250; 119 testicular cancer cases; adjusted hazard ratio (AHR) 1.42, 95% CI, 0.83, 2.45]. Heavy cannabis use (defined as usage of more than 50 times in lifetime, as measured at conscription) was associated with the incidence of testicular cancer (n = 45 250; 119 testicular cancer cases; AHR 2.57, 95% CI, 1.02, 6.50).
