Claim 1: “A growing body of research suggests a controversial, increasingly common habit in the US may be quietly damaging men’s sperm — and doubling their partners’ risk of miscarriage.”
CORROBORATED
Multiple web sources independently report links between male marijuana use and increased miscarriage risk, as well as reduced sperm quality. The first source mentions a 'controversial habit' affecting sperm and miscarriage risk, the second explicitly connects marijuana use to miscarriage rates, and the third discusses oral sex as a mitigating factor (not contradicting the core claim).
