[Sterility and Chlamydia infection. Risk factors].

The authors distributed a questionnaire to 89 patients who consulted them for sterility for reply by themselves. The blame for chlamydia trachomatis infection as a cause of sterility was worked out as a level of IgG above 1/8. The risk factors for being infected with chlamydia trachomatis is above all the number of sexual partners; the odds ratio of 2,68 being significant for those who had more than one partner. The age of marriage and the age at first intercourse do not count. The prevention of the consequences of infection depends on education about the risks and screening for infection when the partner is changed.
