No one cares to do it because it would make women look bad. The knowledge might benefit those men who would choose to looksmax or go MSTOW as a result. We are a gynocentric species and don't care about men. E.g.
- Breast cancer spenditure vs that for prostate cancer. That'll teach you not to have a prostate, you rapist!
- Balding cure = no one cares. Just shave it and be konfident!
- Contraceptive for men = no one cares, just risk those 18 years or get the snip. Man up!
- FGM vs Circumcision = don't you want your penis to look nice for the women who will never see it anyway?
We don't CARE about men. We don't want women to look ADVANTAGED or SHALLOW. We want to believe they are downtrodden and innocent.
