Warfare in the Middle East has created significant demographic and genetic disparities between males and females, primarily driven by high male mortality, patrilineal clan structures, and high rates of stress-induced pregnancy complications.

Key findings regarding these disparities include:
Genetic Bottlenecks: Historical conflicts between patrilineal clans in the region have led to a collapse in Y-chromosome diversity, suggesting a pattern where only a few male lineages survived, while female genetic diversity remained more intact.
Sex Ratios at Birth: Research on regional conflicts, such as in Egypt, has shown dips in male-to-female ratios, potentially due to stress-related, disproportionate miscarriage rates of male fetuses during times of war.
Congenital Anomalies: Studies in conflict zones like Fallujah, Iraq, have reported high rates of congenital malformations (15% of births) and anomalous male-to-female ratios in children under five, attributed to environmental and toxic legacies of war.
Health and Genetic Differences: Female veterans of the Gulf War era have reported higher rates of illness compared to their male counterparts, highlighting a gendered disparity in long-term health consequences.
Reproductive Differences: Recent studies suggest that certain genetic mutations that cause male sterility are more prevalent in the region, which may be linked to differing natural selection pressures on males and females.
Consanguinity and Health: High rates of inbreeding (20% to over 70%) in certain Middle Eastern communities, combined with war-related environmental factors, have led to a high prevalence of autosomal recessive disorders.
