Can men who have chlamydia be asymptomatic for months and then have symptoms just show up?
The only way to absolutely ensure that you do not get chlamydia is to avoid sexual contact. In other words abstinence. In cased where abstinence is not possible, having a long-term, mutually monogamous relationship will ensure that chlamydia is not spread further. If you are not in either of these categories, you should use a latex or polyurethane condom correctly and cosistently. It is important to remember that although condoms reduce the transmission of most STIs dramatically, including chlamydia, they are NOT 100% effective.
