Sex and parasites are two of the most important forces in evolution, shaping everything from the appearance of organisms (sex, by favoring the evolution of ornaments and weapons) to their physiological functioning (parasites, via selection for host defenses). They have been studied both separately and together, with parasite–sex interactions similarly featuring in a wide range of areas in biolo...
