Before the study began, they hypothesized that cannabis would have no impact on the fertility of either men or women, which was the same case in older, similar studies. However, the male subjects who reported smoking cannabis were found to have higher sperm counts compared to those who never used it. But take the findings with a pinch of salt: because scientists still know very little about how cannabis affects fertility, at most, what this study does say is that cannabis had no negative impact on men who were doing fertility treatments.
