What is progesterone gel-vaginal, and how does it work (mechanism of action)?

  • Progesterone is a female hormone and is the principal progestational hormone. Progestational hormones prepare the uterus (the womb) to receive and sustain the fertilized egg. Progesterone promotes the development of the mammary glands, causes changes in the endometrium, which lines the uterus, relaxes uterine smooth muscles, blocks ovulation within the ovaries, and maintains pregnancy.
