An observational study in Obstetric Anal Sphincter Injury, Sexual Dysfunction and the Mode of Deliveries and Pelvic Floor Disorders, sponsored by Tampere University Hospital. Enrolling by invitation at 1 site in Finland. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-15.
Sponsored by Tampere University Hospital · Observational
The goal of this observational study is to understand long-term pelvic floor symptoms and sexual dysfunction after childbirth-related anal sphincter injury in women who gave birth at Tampere University Hospital between 2009 and 2021. The main questions it aims to answer are:
How common are long-term pelvic floor symptoms and sexual dysfunction after sphincter injury? What factors are associated with an increased risk of long-term symptoms?
Additionally, the study explores whether sphincter injury affects desired family size and satisfaction with the mode of delivery in a subsequent pregnancy.
Participants will:
385 studies on the registry are indexed under Sexual Dysfunction, Physiological; 72 are open to participants now.
This study's planned enrollment of 600 is above the median of 176 across 113 observational studies indexed under Sexual Dysfunction, Physiological.

The study population consists of individuals who gave birth at Tampere University Hospital (Tays) between 2009 and 2021 and whose delivery was complicated by an anal sphincter injury (n = 580).

Exclusion Criteria:
-
No pregnancies ending in delivery after obstetric anal sphincter injury
Only cesarean delivery/deliveries after obstetric anal sphincter injury
Vaginal delivery/deliveries after obstetric anal sphincter injury
Pelvic floor symptoms
Pelvic floor symptoms described in the short form of PFDI-20 (Pelvic floor distress inventory) questionnaire. The questionnaire consists of 20 items, each of which is scored from 0 to 4 points. The items are presented in domains describing different pelvic floor symptoms: those associated with pelvic organ prolapse, those associated with defecation, and urinary symptoms. Higher score indicates more distress associated with the symptom. In this study, individual items, domain scores and overall score are compared between the study groups.
Time frame: 5-26 years after the delivery complicated by OASI
Sexual dysfunction
Sexual dysfunction symptoms described in the PISQ-12 (Pelvic organ prolapse/urinary incontinense sexual questionnaire). This instrument includes 12 items that are scored on a scale from 1 to 5, higher score indicating higher sexual function. In this study, each item score as well as total score will be compared between the groups.
Time frame: 5-26 years after the delivery complicated by OASI
Satisfaction regarding the choice of mode of delivery in subsequent delivery
Satisfaction assessed with a numerical rating scale (1 to 10)
Time frame: 5-26 years after the delivery complicated by OASI
Plan to share: No — Finnish legislation prohibits sharing individual participant data.
Start is estimated for Oct 2026; primary completion for Jul 2027, 9 months later.
Of 37 non-industry observational studies under Sexual Dysfunction, Physiological, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 55. This study's planned 9 months is below that.
Counting every sponsor, half of 40 studies reached it within 42 months; a quarter within 11 and three quarters within 65.
Start moved once since we started tracking on Sep 25, 2026: Aug 2026 → Oct 2026, on Oct 15, 2026.
