Dysfunctional labour describes the condition when uterine contractility is too poor to dilate the cervix, and it is the leading cause of emergency Caesarean sections. Recently, insight has been gained into a possible causal mechanism for dysfunctional labour. Study of the physiological mechanisms that produce excitation in the uterus, the subsequent Ca<jats:sup>2<\/jats:sup><jats:sup><jats:bold>+<\/jats:bold><\/jats:sup> signals and biochemical pathway leading to contraction has underpinned this progress. In this review, I give an account of excitation\u2013contraction signalling in the myometrium and explore the implications of recent findings concerning lipid rafts for these processes. I also discuss how changes of pH are fundamentally enmeshed in uterine activity and biochemistry and explore the effect that pH changes will have on human myometrium. Finally, I present the evidence that acidification of the myometrium is correlated with dysfunctional labour and suggest the processes by which it is occurring. It is only by gaining a better understanding of uterine physiology and pathophysiology that progress will be made and research findings translated into clinical benefit for women and their families.<\/jats:p>","DOI":"10.1113\/expphysiol.2007.038125","type":"journal-article","created":{"date-parts":[[2007,4,28]],"date-time":"2007-04-28T00:33:53Z","timestamp":1177720433000},"page":"621-631","source":"Crossref","is-referenced-by-count":111,"title":["Insights
