What do you refuse to get generic versions of?
Billions of women in the world east of Europe all the way to Japan would disagree with you. But then again it’s the bidet shower variety.
It’s not really an opinion, bidets are associated with abnormal vaginal flora and preterm birth.
Your linked study is done with 212 subjects. 212!
With a population that small, you can have any conclusion you’d like. There are billions of people who use bidet showers daily in the world, your study has 212!
If you believe in the scientific method, you should know that a study has to be verified by many independent studies with big enough data samples before it is accepted as fact. You must surely know that there are studies that conclude that the climate change is a hoax. But the overwhelmingly majority makes these handful outliers or flawed studies.
Sigh, I was wondering if this particular misunderstanding of statistics had migrated from reddit to here.
No, you cannot dismiss a study because it “only” has 212 people. 200 people is enough to get an 85% confidence level.
On top of that, it is hardly the only study showing vaginal microflora alteration in bidet users:
https://pubmed.ncbi.nlm.nih.gov/21058441/
Normal microflora (Lactobacillus species) was not present in 42.86% of bidet toilet users, compared to 8.77% of non-users. Fecal bacteria were detected in 50 of the 268 cases (18.66%), 46 cases in users (92%) and only 4 cases in non-users (8%). Contamination by other pathogens was 4 to 6 times higher in users than in non-users.
I get there is a cult of bidet users who will hear no slander of them, but it’s not going to make me spray water from my toilet seat and around my vulva and potentially into my vagina. You are not changing my mind on this and I invite you to read more about sample sizes if you want to do something productive: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6970301/
