🌿 Progesterone & Miscarriage: What You Should Know
Can progesterone supplementation help prevent miscarriage?
For many women, the answer is yes — in the right situations.
🧬 Progesterone is the “pro-gestation” hormone.
It stabilizes the uterine lining, supports early embryo development, and helps your body maintain a healthy early pregnancy. When progesterone levels are low — or when the body struggles to sustain them — the risk of early loss can increase.
Here’s what research shows:
✨ Women with recurrent pregnancy loss may benefit the most.
Studies show that progesterone supplementation can improve live birth rates, especially in women with a history of multiple miscarriages or early pregnancy bleeding.
✨ Progesterone can support implantation & early placental development.
It helps calm uterine contractions, modulates immune response, and creates the stable environment a developing embryo needs.
✨ It’s safe and well-tolerated.
Large reviews show progesterone does NOT increase birth defects or major complications.
✨ It’s individualized.
Not every miscarriage is caused by low progesterone — but for the women who do benefit, supplementation can be the missing piece that helps them carry a pregnancy successfully.
💛 Bottom Line
Progesterone won’t prevent every miscarriage, but for many women with early pregnancy bleeding, luteal phase defects, or multiple prior losses, supplementation can meaningfully increase the chance of a healthy pregnancy.
