An individual with a female reproductive system can get pregnant if sperm reaches one of their eggs (ova). Contraception tries to stop this happening by keeping the egg and sperm apart or by stopping egg production. One method of contraception is the internal condom. 

What are Internal Condoms?

Internal condoms are made from thin, soft plastic called polyurethane (some condoms are made from this too). They are worn inside the vagina to prevent semen getting to the womb. 

When used correctly during vaginal sex, they help to protect against pregnancy and sexually transmitted infections (STIs). Condoms are the only contraception that protect against both pregnancy and STIs.  

At a Glance: Facts About the Internal Condom

  • If used correctly and consistently, internal condoms are 95% effective. This means that five out of 100 individuals using internal condoms as contraception will become pregnant in a year. 
  • Using internal condoms protects against both pregnancy and STIs. 
  • An internal condom needs to be placed inside the vagina before there is any contact between the vagina and the penis. 
  • Internal condoms need to be stored in places that aren’t too hot or too cold, and away from sharp or rough surfaces that could tear them or wear them away. 
  • Always buy condoms that have the CE mark on the packet. This means they’ve been tested to European safety standards. Condoms that don’t have the CE mark won’t meet these standards, so don’t use them. 
  • Internal condoms may not be suitable for those who are not comfortable touching their genital area. 
  • Do not use an internal condom more than once. If you have sex again, use a new internal condom. 

How internal condoms work 

The internal condom is worn inside the vagina to stop sperm getting to the womb. 

It is important to use condoms correctly, and to make sure the penis doesn’t make contact with the vagina before a condom has been put in. This is because semen can come out of the penis before full ejaculation (come). An internal condom can be put in up to eight hours before sex. 

Who can use internal condoms 

Most people can safely use condoms. However, they may not be the most suitable method of contraception for those who do not feel comfortable touching their genital area. 

Advantages and Disadvantages of an IUS

 

It is important to consider which form of contraception is right for you and your partner. Take care to use condoms correctly, and consider using other forms of contraception for extra protection. 

Advantages Disadvantages
By preventing the exchange of bodily fluids (semen and vaginal fluid), internal condoms help to protect against many STIs, including HIV.  Some couples find that putting a condom in can interrupt sex. To get around this, try making using a condom part of foreplay or insert the internal condom in advance. 
When used correctly and consistently, condoms are a reliable method of preventing pregnancy.  Condoms are very strong, but may split or tear if not used properly. 
You only need to use them when you have sex – they do not need advance preparation and are suitable for unplanned sex.  Internal condoms are not as widely available and are more expensive to buy. 
In most cases, there are no medical side effects from using condoms.   
Internal condoms can be inserted up to eight hours before sex, and mean that both share the responsibility for using condoms with their partner.   

 

Can anything make condoms less effective? 

Sperm can sometimes get into the vagina during sex, even when using a condom. This may happen if: 

  • the penis touches the area around the vagina before a condom is put in 
  • the internal condom gets pushed too far into the vagina 
  • the penis enters the vagina outside the internal condom by mistake 
  • the condom gets damaged by sharp fingernails or jewellery 

Although internal condoms (when used correctly) offer reliable protection against pregnancy, using an additional method of contraception will protect you against pregnancy if the internal condom fails. If an internal condom slips or fails, you can use emergency contraception to help to prevent pregnancy. This is for emergencies only, and shouldn’t be used as a regular form of contraception. 

Using lubricant 

Condoms come ready lubricated, to make them easier to use, but you may also like to use additional lubricant. This is particularly advised when using condoms for anal sex to reduce the chance of the condom splitting. 
Any kind of lubricant can be used with internal polyurethane condoms. If you are using latex condoms, do not use oil-based lubricants, such as body oil, petroleum jelly or creams (like Vaseline), as they can damage the latex and make the condom more likely to split. 

Risks 

There are no serious risks associated with using internal condoms. 

Where to get internal condoms 

You can get free condoms from: 

You can buy condoms and internal condoms from: 

  • pharmacies 
  • supermarkets 
  • websites 
  • mail-order catalogues 
  • vending machines in some public toilets 
  • some petrol stations 
  • Freedoms 

If you buy condoms online, make sure you buy them from a pharmacist or other legitimate retailer. Always choose condoms that carry the European CE mark or British BSI Kitemark as a sign of quality assurance. 

Contraception services are free and confidential, including for people under the age of 16. 

If you're under 16

If you’re under 16 and want contraception, the doctor, nurse or pharmacists won’t tell your parents (or carer) as long as they believe you fully understand the information you’re given, and your decisions. 

Doctors and nurses work under strict guidelines when dealing with young people under 16. They’ll encourage you to consider telling your parents, but they won’t make you. The only time that a professional might want to tell someone else is if they believe you’re at risk of harm, such as abuse. The risk would need to be serious, and they would usually discuss this with you first.
