Hormonal

Adding progestins to oestrogen therapy enhances the protective effect against hip fractures compared to oestrogen alone, allowing for lower oestrogen doses.

If you are considering hormone replacement therapy (HRT) for hip fracture prevention, adding progestins to oestrogen may provide greater protection than oestrogen alone. This combination may also allow for lower doses of oestrogen. Discuss the benefits and risks of combined therapy with your healthcare provider.
