Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

The Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Optimal timing for induction of labor in normotensive women: A retrospective cohort study

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 365-371, April 2025.
Abstract Objective Labor induction is offered to reduce the risk of stillbirth at late term (41+0 to 41+6) but earlier induction in normotensive singleton pregnancies is supported by weak evidence. The aim of the present study was to investigate the optimal timing for induction in normotensive women.

A comparison in maternal and neonatal outcomes between mild fundal pressure and vacuum extraction for shortening the second stage of labor

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Mild fundal pressure (MFP) and vacuum extraction (VE) are interventions used during the second stage of labor when clinical intervention is required. While VE is well established with standardized training and predictable risks, MFP remains controversial with limited comparative data. This study aimed to compare maternal and neonatal
