The study later got retracted due to backlash but the fact that it happened at all if fucking baffling.
Don’t forget this study that instead of studying the causes or cures for endo studied the mental effects of the men in a relationship with someone who has endo.
I get the reasoning but is there even that much of a correlation between physical attractiveness and likeliness to reproduce?
Yep - I learned this from House:
https://en.wikipedia.org/wiki/Complete_androgen_insensitivity_syndrome (CAIS)

These are genetically male individuals (XY) who have internal un-descended testicles and present completely as a female phenotype because their body is incapable of reacting to testosterone.
Not only that, but they usually present as quite attractive women since they’re flush with estrogen, and tend to have sparse pubic, leg, and arm hair. No uterus either which may be a pro for some guys.
