Full Term Gestation & Labor Readiness
Educational content only — not medical advice.
Embryonic Age: 38 weeks post-fertilization — Full-term gestational endpoint. All physiological systems are primed for autonomous neonatal life; maternal-fetal hormonal cascades trigger labor contractions.
Biometric Measurements
- Approximate Length: 51.2 سم (CRL/CHL - INTERGROWTH-21st)
- Estimated Weight: 3.4 كجم (Hadlock)
- Fundal Height: 38 cm
- Size Comparison: Full Watermelon / Pumpkin
Key Fetal Milestones
- Cranial bones remain unossified at fontanelles to allow head molding through birth canal
- Peak maternal immunoglobulin G (IgG) placental transfer conferring passive neonatal immunity
- Ready for first neonatal breath: pulmonary fluid clearance triggered by catecholamine surge
Maternal Changes
Cervical effacement and progressive dilation; strong coordinated myometrial contractions drive the stages of active labor.
