Abstract Past reproductive effort allows males to assess their ability acquire mates, but it also consumes resources that can reduce future competitive ability. Few studies have examined how a male’s history affects his subsequent mate choice, and, date, no study has determined the relative contribution of past mating behavior and ejaculate production because these two forms investment are naturally highly correlated. Here, we disentangled effects in mosquitofish (Gambusia holbrooki) by experimentally preventing some from ejaculating when trying mate. We assessed effect on choice comparing had previously been with or without access females male rivals for 8 16 weeks ejaculation either could not they weeks. Reproductive treatment did affect attractiveness, choice. Somewhat surprisingly, five six treatment-by-age at testing combinations, preferred female vicinity rival over solitary female. This preference was marginally stronger engaged were unaffected production. discuss potential benefits associating another seeking mates. is first quantify influence pre- post-copulatory
