Design outcomes

Primary

Measure	Time frame
1. Reported coital activity from diary (kept from recruitment to delivery - expected to be only days worth in most instances) 2. Labour onset on or before appointment for labour induction: spontaneous labour (defined as spontaneous uterine contractions resulting in cervical dilatation of at least 3 cm) or pre-labour rupture of membranes on or before appointment date for labour induction Primary outcomes should typically be resolved within one week of recruitment (no requirement for long term follow up).	—

Secondary

Measure	Time frame
1. Reported orgasms 2. Mode of delivery 3. Recruitment to birth admission interval 4. Initial Bishop Score at the admission for birth 5. Pre-labour rupture of membranes 6. Use of dinoprostone 7. Use of oxytocin infusion during labour 8. Maternal fever 9. Epidural use in labour 10. Meconium stained liquor 11. Delivery blood loss 12. Neonatal admission 13. Apgar score at five minutes 14.
