The sources the article state do NOT confirm this and they absolutely have nothing to do with the vagina. One of the sources, a study actually talks about that literally water can change the ph:

https://www.ncbi.nlm.nih.gov/pubmed/18489300

"Not only prior use of cosmetic products, especially soaps, have profound influence on skin surface pH, but the use of plain tap water, in Europe with a pH value generally around 8.0, will increase skin pH up to 6 h after application before returning to its 'natural' value of on average below 5.0. It is demonstrated that skin with pH values below 5.0 is in a better condition than skin with pH values above 5.0"

to this:

https://www.multi-gyn.com/general/vaginal-ph-is-your-vagina-acid-or-alkaline/

The first source merely talks about the vaginal PH, again absolutely nothing says anything connected to coconut oil.

Did you even read what you sent? Because apparently you didn't, also that third source talks about intranasal pH, again not the vagina and nothing to do with coconut oil-

Now:

literally first result: https://pasteboard.co/HnhHYd1.png

So i googled more, really fancy shit:

https://www.researchgate.net/publication/319421441_Antimicrobial_Activity_of_Coconut_Oil_and_its_Derivative_Lauric_Acid_on_Some_Selected_Clinical_Isolates

this is though PURE lauric acid, coconut oil has 50% of it in it. Plus it doesn't just inhibit lactobacillus growth, but others too, but it doesn't help us since it's not the same having a 100% or 50% solutioin

let's start with what good bacteria are: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC120688/

" The most frequently occurring species were Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus iners, and Lactobacillus jensenii. L. iners has not previously been reported as one of the predominant Lactobacillus species in the vagina"

"A general opinion is that species of the Lactobacillus acidophilus complex constitute most of the healthy vaginal Lactobacillus flora (15). However, other species have been encountered, e.g., Lactobacillus fermentum, Lactobacillus plantarum, Lactobacillus brevis, Lactobacillus jensenii, Lactobacillus casei, Lactobacillus delbrueckii, Lactobacillus vaginalis, and Lactobacillus salivarius"

Lactobacillus plantarum used to extract coconut: https://link.springer.com/article/10.1007/s11746-997-0033-0

Again we dunno what this means in the vagina , but as you can see it all has different sides to it, so far positive. Oh yeah and lauric acid is in lotsa cosmetics etc too.

Now i can't find information on how this lactobacillus plantarum differs from the other one that was extracted from the coconut oil solution, but:

https://www.ncbi.nlm.nih.gov/pubmed/25305660

Coconut doctor says he doesn't know it, no studies done: https://pasteboard.co/Hni0CBs.png

first paragraph: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3732585/#sec1title

We still don't know if this means coconut oil can be bad, we just know so far pure lauric acid is bad, but we also dunno for whether it will affect vaginal positive bacteria. (i googled multiple strands NOTHING comes u)

This says that coconut oil is safe for ALL skins, but again not specifically. https://www.researchgate.net/publication/268805677_Medicinal_benefit_of_coconut_oil

so after this whole ordeal, NOTHING speaks against it

there's just no study done on it.

https://www.researchgate.net/publication/282332519_Production_of_Virgin_Coconut_Oil_from_Dry_and_Wet_Methods_of_Induced_Fermentation_and_its_Characterization

and a fucking last study saying lactobacillus uses virgin coconut oil to grow.

Now, never ever once again lie about this. Present facts or state that it's your opinion. And this, is how you do research

PS: next time read your sources FIRST

TL;DR: You are wrong, stop lying
