Femodene contraceptive pills work in three different ways to prevent pregnancies from occurring.
Firstly, they increase the consistency of the mucus around the neck of the womb, which prevents sperm from reaching an egg.
Secondly, by adjusting the levels of hormones throughout the cycle, Femodene prevents an egg from being released in the first place, meaning even if the sperm does reach the womb, there is no egg there to fertilise.
Lastly, it alters the lining of the womb, making it inhospitable for the egg to embed itself. This means that even in the unlikely event that the first two barriers fail, fertilisation is still highly unlikely.
For the above to happen, the pill needs to be taken correctly. When it’s not taken according to these instructions, it becomes less effective at preventing pregnancy.
