If youíre vegan, you may not realise that the contraception you use might contain animal products.


Most condoms are latex and contain casein, a protein which is found in milk. Casein is added to help make the latex smooth during the manufacturing process.


There are even some condoms which are made using lambís intestines, although these arenít as common as they used to be. In fact, these lambskin condoms are not recommended for protecting yourself against sexually-transmitted diseases as they are porous, although they are effective at preventing pregnancy.


But donít despair, there are lots of vegan condoms on the market so you can practise safe sex without compromising on your principles. You may also want to avoid condoms which contain casein if you suffer from a milk allergy as it is possible you could experience a reaction.


One way of avoiding casein is to buy non-latex condoms which offer just as much protection from unplanned pregnancy and sexually-transmitted infections.


Funky Condom sells LifeStyles SKYN condoms which are made from polyisoprene and are vegan. Other non-latex condoms like Durex RealFeel are also made without casein and so are a good choice if you are trying to avoid using contraception which contains animal products.


Condomi condoms used to be recognised as vegan by the Vegan Society. However, after some changes to the manufacturing process, there have been claims that they are no longer vegan but Condomi state all their products are free from animal derivatives.


It is not just non-latex condoms which are vegan-friendly. Some manufacturers make latex condoms without using casein or any other animal products.


One of these brands is Kimono, a Japanese condom manufacturer which uses no animal or milk proteins. Funky Condom sells five products from Kimono, including Kimono Thin Maxx Large, Kimono Thin and Kimono MicroThin Large.
