Why is progesterone used in HRT?
Medically reviewed by Dr. Nathan Roth, MDCM, FRCSC, FACOG · Updated 2026-07-26
Why is progesterone used in HRT?
If you have a uterus and take systemic estrogen, a progestogen (such as micronized progesterone) is added to protect the endometrial lining from overstimulation. Women without a uterus often use estrogen alone. HormoneFit individualizes progesterone type, dose, and schedule for Ontario patients.
- Protects the endometrium when systemic estrogen is used
- Micronized progesterone is a common bioidentical option
- May help sleep for some women when taken at night
- Side effects can include spotting, breast tenderness, or mood changes
- Not always required after hysterectomy
