Objective The impact of maternal stress on birth outcomes is well established in the scientific
research. The sex ratio at birth (SRB), namely the ratio of male to female live births, shows …

The secondary sex ratio (SSR), defined as the ratio of male to female offspring at birth, has
garnered significant scientific interest due to its potential impact on population dynamics and …

Background The sex ratio at birth (male live births divided by total live births) may be a
sentinel health indicator. Stressful events reduce this ratio 3–5 months later by increasing …

Objectives The sex ratio at birth (SRB), calculated as male divided by total live births, is an
important indicator of population health. Typically, male live births slightly outnumber female …

Abstract The Trivers–Willard hypothesis predicts that mammalian parents in poor
environmental conditions will favor the offspring sex with more reliable chance of …

The sex ratio at birth (ratio of males to females) has been known to be affected by
exogenous shocks such as wars, pollution, natural catastrophes, economic crises, and …

Objective: The sex ratio at birth, defined as males/total (M/T) approximates 0.515 but is
affected by many factors. Acute and chronic stress have been shown to lower M/T, and both …

The Handbook of Sex Differences is a four-volume reference work assembled and written to
assess sex differences in human traits (although findings regarding other species are also …

The sex ratio (ratio of boys to girls) at birth (SRB) is about 1.05 (about 105 males to 100
females) under normal conditions and could be an indicator for monitoring demographic …

The secondary sex ratio (SSR), indicating the ratio of male to female live births, has
garnered considerable attention within the realms of reproductive biology and public health …
