Funny how this gets burried in the articles. . .here are a few from an article about it. . . http://www.womenshealth.gov/news/headlines/668439.cfm

the findings aren't conclusive. . .

The new study examined 163 patients who were diagnosed with the most common type of testicular cancer. They were diagnosed between 1986 and 1991 in Los Angeles, and researchers asked about their drug use during in-person interviews.

The researchers compared them to 292 healthy men of similar races, ages and ethnicities.

The study found that of the men with testicular cancer who answered questions about marijuana use, 81 percent had tried the drug. Of the healthy men, 76 percent had tried marijuana.
