Progesterone is a hormone released by the corpus luteum in the ovary. It plays important roles in the menstrual cycle and in maintaining the early stages of pregnancy. It may also be involved in the growth of certain cancers.
Ovulation is called the luteal stage, when the egg is released into the fallopian tube. After ovulation, progesterone levels go up for about five days before going back down. If pregnancy occurs, your progesterone levels will slowly rise from the ninth week of pregnancy until the 32nd week. The placenta will begin to make progesterone after 12 weeks to help your pregnancy stay healthy.
