Effectiveness
How Microgestin 1/20 Affects Patients
Norethisterone is a type of pill taken by mouth that can be used for birth control or to treat other hormone-related conditions such as menopause or endometriosis. It acts like the hormone progesterone but with a much stronger effect. Norethisterone works by changing the function of the cervix and uterus and blocking hormones released by the pituitary gland that are involved in egg formation. Taking this kind of hormonal birth control may slightly increase the risk of breast cancer, so patients should be aware of this risk and regularly perform self-exams to check for any potential lumps.
How Microgestin 1/20 works in the body
Norethisterone helps prevent pregnancy by making the cervical mucus thicker and harder for sperm to get through. It also makes the endometrium (uterine lining) less favorable for an egg to attach itself. Norethisterone works by preventing the body from releasing hormones that cause ovulation. In menopausal women, norethisterone is used as part of hormone replacement therapy to prevent endometrial hyperplasia, which can lead to cancer. Finally, norethisterone has a low affinity for other steroid receptors, such as the androgen receptor and glucocorticoid receptor, which may be
