Abstract Many simultaneously hermaphroditic animals cross-inseminate when copulating, even though unilateral sperm exchange is functionally possible. The question is why reciprocity is the rule. This study addresses sperm exchange in a hermaphroditic planarian flatworm, Dugesia polychroa, in which self-fertilisation does not occur. We investigated the availability of self sperm for inseminating a partner, how self sperm affects the likelihood of sperm donation, and whether sperm donation… CONTINUE READING
