monogyny
Monogyny is a specialised mating system in which a male can only mate with one female throughout his lifetime but the female may mate with more than one male. In this system the males generally provide no paternal care. 〔Andrade, M.C.B., & Kasumovic, M. Terminal Investment Strategies and Male Mate Choice: Extreme Tests of Bateman. ''Integrative and Comparative Biology', 2005, pp. 838-847〕 In many spider species that are monogynous, the males have two copulatory organs, which allows them to mate a maximum of twice throughout their lifetime. 〔Lutz Fromhage, McNamara, & Houston. A Model for the Evolutionary Maintenance of Monogyny in Spiders. ''Journal of Theoretical Biology'',2008, pp. 524-531 〕 As is commonly seen in honeybees, ants and certain spider species, a male may put all his energy into a single copulation, knowing that this will lower his overall fitness. During copulation monogynous males have adapted to cause self genital damage or even death to increase their chances of paternity.
== Definition and distinction ==
Monogyny is one of several mating systems observed in nature, in which a male mates only once; females, however, may mate with multiple males. It is important to emphasize the distinctions between monogyny and polyandry, and monogyny and monogamy. Polyandry is a mating system by which a female mates with more than one male; the male, in turn, can also mate with more than the one female. In a monogamous setting, both male and female consent to having only one mate at any one time and thus mate only with that partner for that time period. Hence, monogyny is sometimes referred to as male monogamy because the male only mates with one female.〔Lutz Fromhage, McNamara, & Houston.
