what are Vaginal Rugae there for?

Your vagina isn't just a smooth tube... and those ridges are there for a reason.

They're called vaginal rugae which are folds in the vaginal wall that allow it to stretch, expand and contract. During labour, they help your body adapt as your baby moves down, before gradually returning towards their usual shape after birth.

Our bodies are full of incredible design features that often go unnoticed until we understand them.

Fun fact: Those little ridges don't stay the same throughout life. After menopause, they often become much flatter as oestrogen levels fall and the vaginal tissue becomes thinner.
