- TL;DR Summary
- I read a study with limited exclusion criteria, but does it do its job correctly?
I read a study that linked cell phone use to infertility. They monitored 2,110 men from 1993-2007. However, they picked all of their subjects from an infertility clinic, therefore their subjects were already experiencing fertility issues. They tried to correct for this bias by having these exclusion criteria:
Is this a good exclusion critera, or is the study still flawed because they haven't excluded all possible factors that make someone infertile? (It sounds like they didn't measure key things, like BMI, stress, bathing habits, etc.)
Although smoking or alcohol consumption as well as systemic diseases, orchitis or varicocele were exclusion criteria, no other confounders were investigated
