While the response of testis length to variation in the intensity of sperm competition is well documented across many taxa, few studies address the importance of testis size in determining other components of male reproductive success ( such as mating frequency) or the significance of size variation in accessory reproductive organs. Accessory gland length, but not testis length, is both phenotypically and genetically correlated with male mating frequency in the stalk-eyed fly Cyrtodiopsis dalmanni. Here we directly manipulate male mating status to investigate the effect of copulation on the size of both the testes and the accessory glands of C. dalmanni.Results: Accessory gland length was positively correlated with male mating frequency. Copulation induced a significant decrease in accessory gland size. The size of the accessory glands then recovered slowly over the next 8 - 48 hours. Neither testis length nor testis area was altered by copulation.Conclusion: These results reveal that the time course of accessory gland recovery corresponds to field observations of mating behaviour and suggest that accessory gland size may limit male mating frequency in C. dalmanni. date: 2005-06-09 publisher: BIOMED CENTRAL LTD official_url: http://dx.doi.org/10.1186/1471-2148-5-37 vfaculties: VFLS oa_status: green pmcid: PMC1180822 language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_batch elements_source: Web of Science elements_id: 69959 doi: 10.1186/1471-2148-5-37 language_elements: EN lyricists_name: CHAPMAN, TRACEY lyricists_name: Fowler, Kevin lyricists_name: Pomiankowski, Andrew lyricists_name: ROGERS, DAVID lyricists_id: TCHAP22 lyricists_id: KFOWL83 lyricists_id: APOMI03 lyricists_id: DWROG07 full_text_status: public publication: BMC Evolutionary Biology volume: 5 article_number: 37 pagerange: - issn: 1471-2148 citation: Rogers, DW; Chapman, T; Fowler, K; Pomiankowski, A; (2005) Mating-induced reduction in accessory reproductive organ size in the stalk-eyed fly Cyrtodiopsis dalmanni - art. no. 36.
