Here's some food for thought: it is possible to make yogurt using bacteria from a woman's Vajayjay, but it's probably not a good idea.
Last August, Cecilia Westbrook, an MD/PhD student at the university of Wisconsin, Madison, decided to see if the stomach-churning idea was feasible, according to VICE. Westbrook noted that the most common bacteria found in a healthy Vajayjay was lactobacillus , the same bacteria commonly found in yogurt. She figured she could easily whip up a batch of yogurt just by extracting some of her vajayjay's bacteria with wooden spoon
Homemade yogurt is traditionally made by mixing a small amount of a yogurt starter culture with some milk and heating it.However, Westbrook discovered there was not much information on making yogurt with v**inal bacteria — or much information on va**inal bacteria at all, according to an interview she gave to Jezebel.
“I was actually surprised to know that we really don’t know a lot about vaginal flora. There’s really been only one or maybe two big studies and, interestingly, most of the information that we do know about is from white women, which suggests that there might be some indication that people from different ethnic backgrounds might have different flora.”
To do the experiment, Westbrook used three bowls: One with yogurt made with a traditional starter culture, one with just plain milk, one with just milk and her own bodily contribution.Westbrook left out the batches overnight and awoke to find a decent amount of yogurt in that third bowl, according to Westbrook’s friend, Janet Jay, who wrote the VICE article on the experiment.
