Consistent and correct use of latex condoms reduces the risk for many STDs that are transmitted by genital fluids (STDs such as chlamydia, gonorrhea, and trichomoniasis).
How effective are condoms at preventing chlamydia?
Condoms are 98% effective at protecting against most STIs like chlamydia and gonorrhoea. However, condoms don't protect you from all STIs such as herpes, genital warts and syphilis which can be spread from skin-to-skin contact.
Can chlamydia spread through condoms?
Since chlamydia can be transmitted even if the penis or tongue does not completely enter the vagina, mouth or rectum, using latex condoms at the beginning of sexual contact until there is no longer skin contact is the best form of prevention.
