Live births between February and May exceed the annual average, those between October and January do not reach it. Still births prove to be higher between November and April, and lower between June and September. Premature births are less frequent from June to October. In cases of spontaneous abortions, no seasonal change was found. Conceptions grow rarer in the late winter and early spring months, to become more frequent in the summer months. The data are based on the outcome of pregnancies in Hungary in the years 1957–1963.
