A molecular method of identifying sex in three-spined sticklebacks Gasterosteus aculeatus showed that adult males had a higher prevalence of dermal Glugea anomala cysts than adult females, and young-of-the-year had more than adults. At the end of the breeding season, as predicted, the adult sex ratio became female biased and there was a disproportionate increase in G. anomala parasitism in adult males.
