Why do male seahorses get pregnant instead of females?

Male seahorses can get pregnant because they lack key immunity genes. A missing or dysfunctional part of the vertebrate immune system might explain why male seahorses and pipefishes can carry a pregnancy – and could possibly inspire novel treatments for immune-related diseases in humans and other animals.
