OBJECTIVE: To determine how often women with Ehlers-Danlos syndrome experience obstetric and gynecologic issues both compared with the general population and within the three most common subtypes of Ehlers-Danlos syndrome.

METHODS: An anonymous, prospective, online questionnaire in English was posted to the Ehlers-Danlos National Foundation web site (

RESULTS: Of the 1,769 of those who completed the survey, 1,225 reported a typed diagnosis of Ehlers-Danlos syndrome. Further stratification to the three most common types and reproductive-aged women (n=775) allowed conclusions to be made about differences in rates of obstetric complications and gynecologic dysfunction compared with the general population and between types of Ehlers-Danlos syndrome. Rates of obstetric outcomes for women who reported at least one pregnancy included term pregnancy in 69.7%, preterm birth in 25.2%, spontaneous abortion in 57.2%, and ectopic pregnancy in 5.1%. Infertility was reported by 44.1% of survey respondents. Normal menstrual cycles were reported by only 32.8% with intermenstrual bleeding occurring in 18.6%. Heavy menstrual bleeding was reported by 32.9% survey participants. Gynecologic pain reported included dysmenorrhea by 92.5% and dyspareunia by 77.0%.

CONCLUSION: There is a much greater prevalence of obstetric and gynecologic issues reported by women with Ehlers-Danlos syndrome than in the general population. Additionally, rates differed significantly among the three most common types of Ehlers-Danlos syndrome with vascular type having the highest rates of adverse pregnancy outcomes and menstrual abnormalities. Physician providers should be aware of these challenges and should counsel patients with Ehlers-Danlos syndrome about relevant options and risks.


Women with Ehlers-Danlos syndrome have a much greater prevalence of obstetric and gynecologic issues than do women in the general population.
