Cerazette affects hormones by providing a synthetic form of progesterone (desogestrel), which changes the body’s natural hormonal balance to prevent pregnancy. It mainly works by suppressing ovulation, meaning the ovaries are less likely to release an egg, and it also thickens cervical mucus, making it harder for sperm to reach the uterus. In addition, Cerazette alters the uterine lining, reducing the chances of implantation. Because it does not contain estrogen, its hormonal effects are generally milder than combined birth control pills, which is why it’s often recommended for breastfeeding women or those sensitive to estrogen.  |
