Speaker Sir Lindsay Hoyle has signed a pledge vowing to make the House of Commons "menopause friendly" for staff.
The pledge commits employers to supporting employees affected by the menopause, for example by providing access to fans or flexible working.
Sir Lindsay said women ran his office and he didn't want to see them leave because of the menopause.
The Commons Speaker said it should not be a "taboo subject" that was "swept under the carpet".
