In a number of countries, mainly in Asia, legislation or corporate practice has introduced formal menstrual leave to provide women with either paid or unpaid leave of absence from their employment while they are menstruating.
I en række lande, hovedsageligt i Asien, har lovgivning eller virksomheders reglementer indført officiel menstruationsorlov til at give kvinder enten betalt eller ubetalt orlov fra deres arbejde mens de menstruerer.
