In general pills are very popular. Often pills called also “birth control pills” and/or “combined pills” and/or “combined oral contraceptives (COC)”. The effectiveness of different brands is fluctuating between 95% - 99% (if correctly used!). Combined pills contain estrogens and progesterone (or similar gestagens). The contraceptive effect of COCs is mainly due to inhibition of ovulation; they also cause thickening of the cervical mucus, making it difficult for sperm to pass into the uterine cavity and move towards the fallopian tubes. The receptivity of the uterus (endometrium) to the fertilized eggs is also reduced. It is very important to mention that different brands suit different persons.
Pills are available in packets of:
21 pills, where 1 pill containing the oestrogen/progestogen combination is taken every day for 21
days, then a break from pill-taking occurs for 7 days before starting a new packet; and
28 pills, where 1 pill containing the oestrogen/progestogen combination is taken every day for 21
days then, instead of a break, 7 placebo or iron pills are taken as the other pills in each packet to
complete a full 28-day cycle.
