Abstract
Seasonal variation of live birth sex ratio has been studied among the new-born badies of Visakhapatnam. The live birth sex ratio is inversly related to live birth ratio. Climate has considerable effect on reproductive function. A gradual increase of conceptions from July to February and thereby an increase in birth ratio is noticed. Along with this increase in live birth ratio, the live birth sex ratio has decreased.
