Endometrin is a vaginal insert containing progesterone 100mg. Progesterone is a female hormone important for ovulation and menstruation. Progesterone causes changes in the lining of your uterus, making it easier for a fertilized egg to attach to the uterus at the beginning of pregnancy. Progesterone then helps your body maintain the pregnancy.
Endometrin is used in fertility treatment as part of Assisted Reproductive Technology (ART) for women unable to get pregnant due to a lack of natural progesterone in the body.
Endometrin may also be used for purposes not listed in this medication guide.
