This essay details past and current research into the area of human birth seasonality. It focuses on the contrast in the mechanisms affecting the energetic regulation of ovulation (ERO), which leads to birth seasonality between tropical and temperate subpopulations. In doing so, the seasonal nutritional conditions of females in sub-Saharan Africa and Nepal are evaluated, as well as the climatic and cultural factors that affect the hormonal balance that creates ERO. The essay finds that whereas decreased energy intake causes ERO and therefore birth seasonality in tropical agricultural/pastoral populations, it is increased energy expenditure that has the same effect in temperate agricultural/pastoral populations. Finally, current directions in the field of ERO are briefly explored as they relate to birth outcomes that remain unlinked to seasonality in industrialist populations.
