Your body goes through a lot of changes during menopause. This period in a women's life marks the transition from a reproductive to non-reproductive stage. Progesterone and oestrogen play a key role in your reproductive health. During the menopausal transition, the amount of oestrogen and progesterone produced declines rapidly. However, certain levels of sex hormones are still needed for your body to function. Fortunately, nature has a great solution for this.
