• Fetal status, development, and prenatal diagnostics as bases for obstetric risk assessment, integrating gestational age estimation, intrauterine growth regulation, fetal heart rate/pH monitoring, and progesterone dynamics [2], [4], [5], [7], [20].

• Labor dynamics and uterine function shaping obstetric risk management, through studies of spontaneous contractility, oxytocin sensitivity, and patterns of uterine rupture across delivery settings and cesarean trials [8], [10], [11], [18], [19].

• Abortion and termination practices, clinical experiences, and policy implications across midpregnancy and second-trimester contexts, including hypertonic saline, vacuum aspiration, and mechanical methods in diverse health systems [9], [12], [15], [16], [17].
