What does Norethisterone do to the uterus?
Norethisterone is a progesterone receptor agonist. This means that it binds to the progesterone receptors in the uterus and causes the same effects as progesterone. This results in a thickening of the uterine lining, which makes it less likely for implantation to occur. It can also make the uterine lining less receptive to implantation, and make the uterus hostile to a pregnancy. In some cases, it can also lead to the shedding of the uterine lining, which is known as withdrawal bleeding.
