>>98533452Correlation does not equal causation is the only thing I can really say to that. The UTI study there for example not find an association between extreme grooming and a diagnosis of UTI alone, just in "higher risk" of recurrent UTIs. That to me suggests that shaving alone is not a "cause" for it, it is merely correlated in this particular sample. Other factors were also correlated with it too however, such as having a previous UTI (obviously, to be recurrent), frequent sexual intercourse during the past year, etc.
Here's an example of a study which did not find any correlation between STI risk factors and extreme grooming:
https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0221303None of these necessarily prove any real causation between it, merely an observation of a correlation (or in the case of that one, a lack of one) which even then, is not a very high association. An OR of approximately 1.55 might be of statistical significance, but it isn't suggestive of a strong relationship, for reference the OR of smoking and lung cancer is approximately 20. I would bet there's a higher association with hygiene habits, frequency of sex, or condom use than the "risk" of shaving and contracting a disease.
Basically, my original point. Fearmongering.
