2 What do you need to know about the menstrual cycle?

You can see that the hormones released during the menstrual cycle, oestrogen and progesterone, are produced to support reproduction. These and other hormones are released from glands. Hormones are ‘chemical messengers’ that send messages out to organs and tissues to control health and behaviour. Hormones act to tell you to eat when you are hungry, give you energy when you are stressed and help you sleep at night.
Oestrogen and progesterone do not just control the menstrual cycle, they also contribute to variations in energy, mood, sexual desire, and changes in behaviour across the cycle (Hill, 2019). They also have a role to play in bone health, cardiovascular function and brain health.
