Half of Britons could not identify or describe the function of the urethra (58%), labia (47%) or vagina (52%).
Breaking those results down by gender, we find that six in ten men (59%) and half of women (45%) could not even label the vagina. Slightly more didn’t know what the urethra was (61% of men and 55% of women). Around half of both genders failed to label the labia (52% of men and 43% of women).
The only part of the female genitalia which the majority of both genders labelled correctly was the clitoris, identified correctly by two thirds of men and women (71% of women, 69% of men).
However, that leaves a third of both women and men who did not know what the clitoris was (29% women, 31% men).’

I recall discourse on this and it appears the rising lack of knowledge on female anatomy is due to the growing African and Middle Eastern populations in the UK.
