Progesteron

In women or people assigned female at birth (AFAB), progesterone supports menstruation and helps maintain the early stages of a pregnancy. Too little progesterone can cause complications with pregnancy or produce side effects similar to menopause.

The main function of progesterone is to prepare the endometrium (lining of your uterus) for a fertilized egg to implant and grow. If a pregnancy doesn’t occur, the endometrium sheds during your menstrual period. If conception occurs, progesterone increases to support the pregnancy.
