Study population: Participants include 88 primigravida women at ≥37 weeks of gestation, each with a singleton pregnancy in cephalic presentation. All participants present with medical or obstetric indications for induction of labor, such as post-dates, oligohydramnios, mild preeclampsia, or premature rupture of membranes. Exclusion criteria include prior uterine surgery, multiple pregnancies, malpresentation, placenta previa, vasa previa, non-reassuring fetal status at admission, or maternal infections such as active genital herpes and HIV. A carefully designed sample size calculation ensures adequate power, with a final cohort of 44 women per study arm.
Who may be able to join
- Singleton pregnancy
- Cephalic fetal presentation
- Gestational age ≥37 weeks (confirmed by reliable dating)
- Indication for induction of labor (postdate pregnancy, oligohydramnios, mild preeclampsia, premature rupture of membranes)
Who cannot join
- Previous uterine surgery (e.g., cesarean section, myomectomy)
- Multiple gestation
- Malpresentation
- Placenta previa or vasa previa
- Non-reassuring fetal heart status at admission
- Active genital herpes or HIV infection

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Transvaginal Ultrasound Group (TVUS): | Participants undergo sonographic measurement of cervical length. A CL <28 mm is considered favorable for successful induction. This method provides an objective and reproducible cervical assessment. | |
| Bishop Score Group (BS): | Participants undergo digital vaginal examination to assign Bishop Scores. A score ≥6 is considered favorable for induction. This is the traditional method of assessing cervical readiness. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Rate of vaginal delivery
The proportion of women achieving vaginal delivery after induction of labor within 24 hours of initiation.
Measured: Within 24 hours

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Rate of vaginal delivery (time frame: Within 24 hours). It is what the study was designed to measure, not a finding.
