menstruation
The Spanish word 'menstruación' translates to 'menstruation' in English. It is a term used in female reproductive health indicating the monthly cycle where the uterine wall sheds its lining, commonly known as a 'period'. In this context, it can be used interchangeably between Spanish and English conversations regarding feminine health. It is considered a medical term by nature, and thus holds the same technical significance in both languages.
