Patterns of human reproduction and geographic latitude
Abstract
The present paper offers data to suggest an effect of geographic latitude in regard to the frequency of conception in human populations. The birth statistics from eight countries in different parts of the world have been evaluated. A particularly strong minimum appears to occur in almost all regions but is shifted in time with changing latitude.
