This is a very interesting observation. But definitely it needs a
closer look with data collection not only regarding induction of labour
before 42 wks but also behavioural characteristics e.g, smoking habits,
stress. Other factors like gender of the fetus (1), vaginal fibronectin
concentration around due dates (2) may be important determinants of post-
term pregnancy.
