Climen Contraceptive Pills are a type of oral contraceptive containing a combination of two hormones, estradiol and cyproterone acetate. These pills are designed to prevent pregnancy by inhibiting ovulation, thickening cervical mucus to prevent sperm penetration, and altering the endometrium to reduce the likelihood of implantation. Climen is commonly prescribed for women seeking effective birth control. It is important to take these pills daily at the same time to maintain their contraceptive efficacy.
