Both men and women need to look after their sexual health and take time to understand the issues that surround contraception and sexually transmitted infections (STIs).
For instance there are some STIs, like chlamydia, that you could be carrying without having any symptoms. This infection can affect fertility, so it’s important to make use of the sexual health services available for free on the NHS.
There are so many different types of contraception available and you may want to try several different things before you choose the one you like most. This short video from NHS Choices gives an overview of different types of contraception.
Chlamydia is the most commonly diagnosed sexually transmitted infection among under-25s. Often there are no symptoms, but testing and treatment are simple.
Causes and risk factors Chlamydia is usually passed from one person to another during vaginal, oral or anal sex, or by sharing sex toys. It can live inside cells of the cervix, urethra, rectum and sometimes in the throat and eyes.
