title: A population-based study of pregnancy and delivery characteristics among women with vulvodynia.
abstract: BACKGROUND
  To examine pregnancy and delivery characteristics of women with and without vulvodynia.
  
  
  METHODS
  The authors analyzed 227 vulvodynia cases that were less than 45 years old at pain onset; controls were age matched 1:1 to cases and had no history of vulvar pain. Pregnancy and delivery events were assessed after age at first vulvar pain onset (the reference age) in cases and a matched age in controls.
  
  
  RESULTS
  The authors observed no significant difference between cases and controls in achieving pregnancy after reference age. Also, no difference in pregnancy outcome was observed between cases and controls (P = 0.87). There was an indication that cases were more likely to receive a Cesarean section delivery (P = 0.07). In addition, 37.1% of cases who had vaginal delivery versus 11.3% of controls (P < 0.01) reported pain at 2 months postpartum. Comparing only women with vulvodynia, women who had intermittent pain versus constant pain were more than twice as likely to have a pregnancy (adjusted odds ratio 2.26, 95% CI 1.10-4.60).
  
  
  CONCLUSIONS
  Women with vulvodynia may be as likely as other women to carry their pregnancy to birth; however, they may experience higher rates of Cesarean section delivery and could reflect a selection towards those women with vulvodynia who have inconsistent pain.
