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.

FIRST-Progesterone VGS 200 (for use in the vagina) is used to cause menstrual periods in women who have not yet reached menopause but are not having periods due to a lack of progesterone in the body.

FIRST-Progesterone VGS 200 is also 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.

FIRST-Progesterone VGS 200 is also used to prevent overgrowth in the lining of the uterus in postmenopausal women who are receiving estrogen hormone replacement therapy.
