A 13ft pair of inflatable knickers was spotted in Manchester - after it was revealed a quarter of women could risk their health by being too embarrassed to discuss discharge changes with their GP.

The installation at Cathedral Gardens features bleach-like stains on a pair of 13ft-10ft inflatable knickers and aims to tackle the stigma surrounding vaginal discharge.

The study, commissioned by Daye, reveals embarrassment around vaginal discharge, with more half considering it a taboo subject.

More than two-fifths (42%) admit they feel uncomfortable talking about it, while 25% are even too mortified to flag changes to their doctor - potentially leaving them at risk of health issues.

Despite discharge being a normal and essential part of maintaining vaginal health, one-fifth of those quizzed associate it with being 'unclean' and 31% are unable to identify the key warning signs of infection.

There's also widespread confusion about one of the most common signs of healthy discharge.

As discharge is naturally acidic, it can leave bleach-like marks on dark cotton underwear. This is completely normal, but is something 22% of women believe signals a medical problem.

Of the 1,000 women surveyed 15% assume they have an active infection when they notice these marks and 11% have booked a GP appointment unnecessarily.

Almost half (46%) said they'd avoid asking a pharmacist for advice, while 8% have taken unprescribed medication without medical advice to treat harmless acidic stains.

But it's not just women's health taking a hit - also their underwear drawer.

A mortified 30% of women hide their stained underwear, while one-third (33%) bin perfectly good underwear because of staining.

Almost one-third (29%) of those surveyed said they want better education around vaginal health, while one in four (25%) believe there should be less shame surrounding women's bodies.

To tackle these misconceptions head-on, Daye is flying the 13ftx10ft inflatable knickers at Cathedral Gardens in Manchester on July 31 from 10am-4pm.

Visitors will also be able to get their hands on free period products from the brand.

Valentina Milanova, Daye founder and CEO, said: " Vaginal discharge is a normal, healthy part of the body's natural defence system, yet too many women have grown up believing it's something to feel embarrassed about or hide.

"Understanding what's normal for your body makes it much easier to recognise when something changes.

"Better body literacy helps women seek medical advice sooner when they need it and avoid unnecessary worry when they don't."
