The role of mycoplasma among 81 consecutive pregnancies: a prospective study.

1. Among 41 previously positive and treated pregnant patients who were retreated when pregnant, the fetal wastage was 15%. 2. Among 40 previously negative or never cultured pregnant patients, the fetal wastage was 25%. 3. The incidence of previous major fertility surgery was 32% for the previously positive patients, but only 7% for the previously negative patients. 4. All of the 43 1-year-old children whose mothers received Vibramycin during early pregnancy have now been reported to be normal.
