Working of the pills

Hormones in birth control pills prevent pregnancy by stopping or reducing ovulation which is also the process of releasing the egg from the ovary. They help in thickening the cervical mucus to keep sperm from entering the uterus which in turn prevents pregnancy. It actively acts on thinning the lining of the uterus so that a fertilized egg is less likely to attach to the inner lining in case of fertilization.


These pills or contraceptive medications are used to prevent pregnancy in women. They are composed of hormones such as oestrogen, and progesterone, which are essential in a woman’s body during the reproductive cycle. They are provided by different brands and manufacturers in various packaging. Some formulations offer continuous dosing, which means the absence of any inactive pills, and a woman takes an active pill daily. Alternatively, extended cycle dosing is when inactive medicines in the active pill regimen only occur three to four times per year. This results in a condition where the woman does not experience a period until she takes the inactive pills.
