What is progesterone treatment?

Progesterone is a hormone that during pregnancy helps your uterus (womb) grow and keeps it from having contractions. Treatment with progesterone may help prevent premature birth for some women. Premature birth is birth that happens too early, before 37 weeks of pregnancy. There are two kinds of progesterone treatment:
  1. Vaginal progesterone may help reduce for your risk for premature birth if you have a short cervix and are pregnant with just one baby.
  2. Progesterone shots may help reduce your risk of premature birth if you’ve had a premature baby in the past and you’re pregnant with just one baby.
If you’re pregnant with multiples (twins, triplets or more), progesterone treatment isn’t for you. It’s only for women pregnant with one baby. Talk to your healthcare provider to learn if progesterone treatment is right for you. Learn more at:
