Abstract
Sex ratio was studied among abortuses and infants who died perinatally (9972 cases). Sex begins influencing mortality in the perinatal period, in which a significant increase in the sex ratio is shown (106 males: 100 females--antenatal; 136 males: 100 females--intranatal; 159 males:100 females--within the first 6 days of life).
