There’s no need to totally replace your underwear drawer unless they are damaged or falling apart, thankfully.

The gynaecologist said on TikTok: “I’ve just been sent a video where someone claims that women need to buy new underwear every six to nine months because somehow in six to nine months your underwear magically becomes some kind of infectious catastrophe and that’s simply not the case.

“When people tell you that you need to do really special things with your underwear, that’s just an extension of purity culture – it’s not true at all, they don’t magically become an issue in six to nine months.”
