The transfer of sperm through a physically inflicted wound (wound = trauma [Greek]).
Introduction
Traumatic insemination (TI) is a special form of traumatic mating (TM) that refers to cases where routinely “the partner’s intra- or extragenital integument is wounded by specialized devices in the direct context of copulation” (Lange et al. 2013).
This explanation excludes accidental cases of copulatory wounding, which perhaps can happen in any group of animals with internal fertilization. Other forms of TM refer to cases where only seminal fluid, but no sperm, is transferred through the wound, or traumatic penetration with neither sperm nor seminal fluid transferred (Lange et al. 2013).
Far from being a bizarre, even aberrant, behavior, recent systematic reviews (Lange et al. 2013; Tatarnic et al. 2014; Reinhardt et al. 2014) identified both TM and TI as being...
