Women primarily produce progesterone in the ovaries. Following ovulation, the production of progesterone increases rapidly. Its concentration reaches its peak during the luteal phase of the menstrual cycle, particularly from day 19 to day 22. Progesterone plays several essential roles in the female reproductive system. It prepares the inner lining of the uterus, known as the endometrium, for potential implantation of a fertilized egg. Additionally, it inhibits further ovulation and thickens the cervical mucus, making it more difficult for sperm to penetrate. If fertilization does not occur, the level of progesterone drops, leading to the onset of menstruation. However, in the event of fertilization and successful implantation, the placenta generates a significantly higher amount of progesterone during pregnancy. Throughout this period, progesterone plays a crucial role in preventing miscarriage. It achieves this by reducing the maternal immune response, enabling the acceptance of the p...

If you are trying to conceive, you may already be familiar with the term progesterone. Progesterone is one of female sex hormones. Progesterone is an essential hormone for pregnancy. Without it there would be no successful pregnancy. In women progesterone is mainly made in the ovary. Progesterone level varies during the menstrual cycles and high level after ovulation is seen. The production of progesterone is increasing rapidly after ovulation. Its level is highest during luteal phase especially from day 19 to day 22 of the menstrual cycle. Progesterone prepares uterine inner lining for implantation, helps uterine lining development and make it ready for embryo implantation; it prevents further ovulation and it makes mucus thicker to prevent sperm to penetrate. If pregnancy occurs, it helps to maintain the uterine lining throughout pregnancy; if there is no pregnancy, progesterone level drops and period starts. If fertilization happens, much more progesterone is produced during pregnan...
