You're confused why they're at a fertility clinic if they have a high sperm count? Conception is a two player co-op game and you can't carry your partner.

It's a weird selection of a focus group though. And nothing warrants this headline (although it's par for the course in 2019).

Maybe that's just the only place they could get data

No kidding... This probably means that Cannabis causes infertity by some means other than lowering sperm count. Imagine the statistic: gang members admitted to the hospital were 40 percent less likely than non gang members to be diagnosed with heart disease. That's probably not because they eat a healthy diet and exercise. It's probably because the rest of the population is less likely to be diagnosed with a gunshot wound.

You have missed the point. Nothing in the study mentions a higher rate of reported cannabis use than in the general population. The record scratch is due to implying generalisations based only on a non-typical population of infertile couples without any control.
