A TikTok doctor who calls herself the "v*ginacologist" has revealed the main function of the v*gina – leaving users shocked.

Dr Teresa Irwin, from Texas, US, is an expert in female pelvic dysfunctions but has also worked as a surgeon.

Over the years, she has noticed that patients' health issues are often linked to lack of education on how to treat their bodies.

The doctor regularly takes to TikTok (@dr.teresa.irwin) to share her knowledge with her 89,200 followers, having stunned social media users with a recent video that has racked up 567,300 views and 28,200 likes.

In the clip, Dr Irwin explains the primary function for the v*gina and it's not all about having babies.

Sat in front of a green screen in blue scrubs, she asked the camera and viewers, what they believe is the primary function of a woman's canal.

She goes on to say that when she asks this question in person, the answer is usually "have babies".

Dr Irwin said: "Yes, the v*gina serves the purpose to have babies but we can also have babies through an abdominal incision, otherwise known as a Caesarean section.

"Another answer I get is to have periods and yes the v*gina does the serve the function of having periods.

"So that the build-up of tissue inside of the lining of the uterus, when a woman is not impregnated, is then discharged as blood.

"But that is not the primary function – what is the primary function?

"Sex!

"Why? because once you go through menopause you can no longer have periods and you can no longer have babies.

"But what can you continue to have? Sex!"

Social media users have been left thrilled by the doctor's advice, with many people sharing tidbits from their own sex lives.

"It only gets BETTER!!!! 65 and lovin it!!!!!," wrote one user. [sic]

Someone else commented: "I knew it!! It’s my favorite function!"

Another shocked viewer added: "I thought it was to empty our bladder!"

"Wow, brilliant!!!" said another user. [sic]

"My new favourite doctor!!!!" commented someone else. [sic]

Another said: "Very true doc! well said!" [sic]

Another joked: "My wife apparently didn’t get the message!"

"Thank you for the reminder, I've let mine get a little dusty for the last two years!" joked another user.

She also recently went viral with her facts on the right way to pee for a woman, which included squatting like a cowboy, as well as her video on different types of discharge.
