title: Geophysical variables and behavior: LXXVIII. Lunar phase and birthrate: an update.
abstract: Martens, Kelly, and Saklofske in 1988 examined 21 studies considering the possible relationship between lunar periodicities and birthrate. They reported that the majority of studies uncovered no relationship and that the positive studies were inconsistent in their findings. The present update reports on six additional studies on birthrate and lunar periodicities from five different countries. None of these studies produced evidence of lunar periodicities consistent with folklore or some previous studies.
