Formally, a nuptial gift is a material presentation to a recipient by a donor during or in relation to sexual intercourse that is not simply gametes in order to improve the reproductive fitness of the donor.[1] Often, such a gift will improve the fitness of the recipient as well.[1] This definition implies neutral gifts, costly gifts and beneficial gifts regarding the fitness of the recipient.[1]
Nuptial gifting is at the intersection of sexual selection, nutritional ecology, and life history theory, creating a link between the three.[1][2]
