Copulatory wounding (CW) is widespread in the animal kingdom, but likely
underreported because of its cryptic nature. We use four case studies (Drosophila
flies, Siphopteron slugs, Cimex bugs, and Callosobruchus beetles) to show that CW
entails physiological and life-history costs, but can evolve into a routine
mating strategy that, in some species, involves insemination through the wound.
Although interspecific variation in CW is documented, few data exist on
intraspecific and none on individual differences. Although defensive mechanisms
evolve in the wound recipient, our review also indicates that mating costs in
species with CW are slightly higher than in other species. Whether such costs are
dose- or frequency-dependent, and whether defense occurs as resistance or
tolerance, decisively affects the evolutionary outcome. In addition to sexual
conflict, CW may also become a model system for reproductive isolation. In this
context, we put forward a number of predictions, including (1) occasional CW is
more costly than routine CW, (2) CW is more costly in between- than
within-population matings, and (3) in the presence of CW, selection may favor the
transmission of sexually transmitted diseases if they induce resource allocation.
Finally, we outline, and briefly discuss, several medical implications of CW in
humans.
