Sexual intercourse during pregnancy and preterm delivery: effects of vaginal microorganisms

Article Abstract:

Frequent sexual intercourse in association with certain types of vaginal infections may increase the risk of preterm delivery in pregnant women. Among 13,285 pregnant women, 1,527 (12%) delivered a premature infant. Sexual intercourse one or more times a week at 23 to 26 weeks of pregnancy significantly reduced the risk of preterm delivery in women without a vaginal infection caused by Trichomonas vaginalis, Mycoplasma hominis or Gardnerella vaginalis. Frequent sexual intercourse at 23 to 26 weeks of pregnancy increased the risk of preterm delivery in women with one of these types of vaginal infections. Women with a vaginal infection who did not have frequent sexual intercourse at 23 to 26 weeks of pregnancy did not have a higher risk of preterm delivery.

Is a change in the vaginal flora associated with an increased risk of preterm birth

Article Abstract:

A study was conducted to determine if a change in the vaginal flora was associated with an increased risk of preterm birth, and to determine if metronidazole therapy before 32 weeks increased the risk of preterm birth. It was concluded that changes in vaginal flora might explain the increased risk of preterm birth seen with vaginal clindamycin or oral metronidazole therapy.

Are racial differences in vaginal pH explained by vaginal flora?

Article Abstract:

The study is assessed racial differences in vaginal pH among women without bacterial vaginosis. It shows that the findings strongly suggest that observed racial differences in vaginal pH reflect differences in vaginal flora, and not inherent biological differences in pH.
