--- abstract: "Olfactory cues play an integral role in the organization of events that mediate reproductive success. In a variety of species, priming\r\npheromones, in particular, are important for ensuring reproductive fitness. To date, very little research has focused on how male-emitted\r\npriming pheromones, such as those that regulate the onset of puberty and estrus synchronization in females, affect the reproductive\r\nphysiology of the female Siberian hamster (Phodopus sungorus sungorus). This lack of research may be due to the physiology of the\r\nPhodopus genus; vaginal cytology cannot be used as a reliable indicator of estrus or ovulation. Using a jugular cannulation technique to\r\ndetermine estrous stage by blood analysis of prolactin and luteinizing hormone, we sought to determine if male priming pheromones affect\r\nestrous cyclicity in the female Siberian hamster and, if so, whether the production of these priming pheromones is androgen dependent. Our results showed that females exposed to bedding from mature, intact males showed a significantly higher incidence of proestrus 3 days later than did females exposed to the bedding of mature, gonadectomized males. Therefore, we found that not only do male Siberian hamsters emit chemical signals that induce estrus synchronization, but also that this ability is likely to be androgen dependent." altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - ~ - kristal@buffalo.edu - ~ creators_name: - family: Dodge given: J.C. honourific: Dr. lineage: '' - family: Kristal given: M.B. honourific: Dr. lineage: '' - family: Badura given: L.L. honourific: Dr. lineage: '' date: 2002 date_type: published datestamp: 2013-05-04 23:22:04 department: ~ dir: disk0/00/00/89/55 edit_lock_since: ~ edit_lock_until: 0 edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 8955 fileinfo: /style/images/fileicons/application_pdf.png;/8955/1/Physio%20Behav.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: ~ item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'Whitten effect, estrus, pheromones, testosterone, hamster' lastmod: 2013-05-04 23:22:04 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: 227-231 pubdom: TRUE publication: Physiology & Behavior publisher: Elsevier refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 12 series: ~ source: ~ status_changed: 2013-05-04 23:22:04 subjects: - behav-neuro-sci - bio-ani-behav - bio-behav - bio-pop - neuro-endocrin succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: Male-induced estrus synchronization in the female Siberian hamster (Phodopus sungorus sungorus) type: journalp userid: 88 volume: 77
