Progesterone Role

 Why it is important?

The level of progesterone varies with the menstrual cycle, and is responsible for most of the changes experienced by women during a month. Right after ovulation, the corpus luteum in the ovary starts releasing progesterone. The high level of progesterone causes the increase in temperature experienced by women after ovulation. If the egg is not fertilized, the corpus luteum dies, and progesterone levels drop. As a consequence, the lining of the uterus starts to bleed and is eliminated through menstruation. 

When the progesterone levels are low, the lining of the uterus might not be well prepared for the implantation to take place. Even if the implantation occurs, low levels of progesterone might make it hard for the pregnancy to develop, so the chances of miscarriage is high.
