When you use condoms, you are trusting them with your sexual health but how are they made?

The exact process will vary depending on the manufacturer but all the condoms sold by Funky Condom follow a strict set of procedures to ensure they meet international safety standards.

The following steps are used by Durex to make its latex condoms but other firms may follow a similar process:

1. Chemicals are added to the latex to make it strong and durable. It is then heated to reduce the risk of causing an allergic reaction and to increase its reliability. The latex is then tested.

2. The latex is moved into large storage tanks which are temperature controlled.

3. A line of clean glass formers are then dipped into the tanks so they become coated with a thin layer of latex. They are then dipped a second time before going through a hot oven so it hardens and sets.

4. The condoms are then removed from the glass formers and washed before pharmacologically-safe powders are added.

5. Durex then store their latex condoms for two days to allow the material to mature.

6. The condoms are put through an electronic testing machine which checks each item thoroughly for any flaws, imperfections or holes.

7. The condoms are then put into a machine which carefully inserts them into the correct foil packaging.

8. If the condom is flavoured or lubricated, the lube or flavouring is injected into the packaging at this stage of the manufacturing process.

9. The foil packaging is sealed using heat and marked with an individual batch number and expiry date.

10. The individual condoms are then put into boxes, ready to be sold.

Durex also carries out a number of tests to make sure its products meet safety standards. As well as electronic testing which is carried out on every single condom it produces, more than two million condoms each month are filled with water and suspended for a minute to check there are no leaks. A sample is taken from each batch to identify any potential problems and if any of the condoms fail a test, they are all thrown away.

A sample of condoms is also inflated with air to check their strength and elasticity. Each month this test is carried out on around 500,000 condoms every month.
