Colourful condoms arranged in a line

There are two different types of condoms, male condoms which are worn on the penis, and female condoms which are worn inside the vagina. 

Condoms are made from a very thin latex, synthetic nitrile, polyisoprene or polyurethane, and can be used for vaginal, oral and anal sex.

For men, the size and fit of condoms are important so that they are comfortable and don't break or slip off.

Condoms are the only option that prevents pregnancy and STIs. 

Effectiveness

Positives

  • Easy to obtain - clinics provide them for free
  • Available without the need to see a doctor, nurse or healthcare professional
  • Protect against STIs
  • Gives men and women control over whether and when to have a baby 
  • Sex is easier to clean up after

Negatives

  • Condoms can interrupt sex
  • Condoms can reduce pleasure
  • It can be difficult to ask men to wear condoms
  • Some men worry about condoms and erections
  • Condoms need some skill - knowing how to stop condoms breaking or slipping off

 

    If condoms break or slip off there’s usually a reason

    Condoms can break because they come into contact with things like oil-based lubricants, vaginal medications, sharp fingernails, teeth, or jewellery.  Using a water-based lubricant is important. If condoms are too small they can break. There are many different sizes and brands to suit different penis length and thickness.  

    If a condom is too loose it can slip off. After a man has ejaculated, it's important that he holds the condom down at the base of the penis while he takes his penis out.

    If the condom breaks or comes off, emergency contraception might be needed

    The morning after pill (emergency contraception) can be bought from pharmacies. GP surgeries, family planning clinics and sexual health clinics can also provide the emergency copper coil and morning after pills.  

    Condoms have a shelf life

    Condoms have expiry dates. They can also weaken in different conditions, such as in hot places or if kept in sunlight.  

    Two is not better than one

    Doubling up and using two condoms at the same time actually increases the chances of the condoms breaking. 

    A new condom needs to be used each time. 

    Condom problems

    It’s not one size fits all –  there are different varieties and sizes of condoms. Condoms can feel too loose or too tight, which can result in less pleasure. Choosing the right size of condom can help.  

    Some men lose their erection when a condom is first put on – being sexual without penetration can allow time to get hard again. The right size of condom will also help, and practising being slick about using them.

    If condoms are causing a sore vagina, using a small amount of water-based lubricant in the vagina can help.

    Some people are allergic to latex, and get soreness or a rash. Non-latex condoms are available.

    Good to know

    The size and fit of condoms matters a lot. Too tight and they break, too loose and they slip off.

    How much effort are condoms?

    Condoms are simple in theory but complicated in practice.

    It can be hard to use condoms in the heat of the moment, and they can affect sexual pleasure.

    Condoms are quite a lot of effort: having them available, communicating about using them, putting it on correctly (with no air inside), and making sure it stays on when pulling out.

    Some people find that putting on a condom interrupts sex, although you can find ways round this, like putting it on as part of foreplay.

    If a condom breaks or comes off,  a woman may need to get emergency contraception (the morning after pill or IUD

    How effective are condoms?

    It depends.  When used every single time, and with no problems, condoms are about 98% effective – meaning that if 100 women used condoms for a year, about 2 of them will have an unplanned pregnancy.  However, allowing for the ups and downs of life, the average user can expect them to be around 85% effective – meaning that if 100 women used condoms for a year, about 15 of them will have an unplanned pregnancy. 

    Female condoms are about 95% effective – meaning that if 100 women used female condoms for a year, about 5 of them will have an unplanned pregnancy.  However, the average user can expect them to be around 79% effective – meaning that if 100 women used female condoms for a year, about 21 of them will have an unplanned pregnancy.

    How do they work?

    Simple concept - condoms stop sperm from getting inside the vagina and travelling up to fertilise an egg.  Find out more about how pregnancy happens here
