Quantitative transcervical uterine cultures in asymptomatic women using an intrauterine contraceptive device

Quantitative transcervical uterine cultures were obtained in 100 asymptomatic women using intrauterine contraceptive devices for varying periods. Twenty women using barrier forms of contraception served as controls. Cultures were obtained safely and satisfactorily without trauma to either the endocervix or endometrium. It was found that normal uterine sterility was significantly compromised in women using an intrauterine contraceptive device. The number of intrauterine organisms cultured was associated with neither the type of intrauterine contraceptive device (Cu-7, Lippes Loop, Saf-T-Coil) nor the duration of use (less than one month to greater than five years).
