What is Progesterone and what is its relationship to estrogen?
Progesterone is one of two primary hormones produced by the female body. When a woman’s monthly cycle is functioning correctly, estrogen is the dominant hormone during the first two weeks after the start of her menstrual cycle. In response to ovulation, estrogen levels drop and progesterone levels rise and assume dominance for the final two weeks of the month. When progesterone levels drop the next menstrual cycle begins in about 48 hours. Progesterone is used by the body for the production of estrogen and cortisone.
