Condoms have different manufacturers and ingredients, and their shelf life varies. Most condoms have a shelf life of 5 years, while condoms containing drugs for delay and aphrodisiacs usually have a shelf life of 3 years, depending on the instructions. Condoms are worn on the outside of the penis during sex to prevent semen from entering the woman’s vagina and provide contraception. In addition, condoms are also used for the prevention of sexually transmitted diseases. As the material is latex, polyurethane, etc., it can age and break over time, so condoms need to be used within the shelf life to be safe, otherwise it is easy to cause contraceptive failure due to quality problems. It is best to keep condoms in the shade to avoid them becoming sticky and brittle, which can affect their use. It is recommended to use the regular manufacturers of condoms, and when buying condoms should pay attention to observe the date of production, so as not to use expired condoms.
