Hyperandrogenism is a major PCOS characteristic and evidence supports it playing a key role in PCOS pathogenesis. Classically, androgens can act directly through the androgen receptor (AR) or, indirectly, following aromatization, via the estrogen receptor (ER). We investigated the mechanism of androgenic actions driving PCOS by comparing the capacity of non-aromatizable dihydrotestosterone (DHT) and aromatizable testosterone to induce PCOS traits in WT and\n                    <jats:italic>Ar<\/jats:italic>\n                    -knockout (ARKO) mice. DHT and testosterone induced the reproductive PCOS-like features of acyclicity and anovulation in WT females. In ARKO mice, DHT did not cause reproductive dysfunction; however, testosterone treatment induced irregular cycles and ovulatory disruption. These findings indicate that direct AR actions and indirect, likely ER, actions of androgens are important mediators of PCOS reproductive traits. DHT, but not testosterone, induced an increase in body weight, body fat, serum cholesterol and adipocyte hypertrophy in WT mice, but neither androgen induced these metabolic features in ARKO mice. These data infer that direct AR-driven mechanisms are key in driving the development of PCOS metabolic traits. Overall, these findings demonstrate that differing PCOS traits can be mediated via different steroid signaling pathways and indicate that a phenotype-based treatment approach would ensure effective targeting of the underlying mechanisms.\n                  <\/jats:p>","DOI":"10.1530\/joe-19-0530","type":"journal-article","created":{"date-parts":[[2020,3,31]],"date-time":"2020-03-31T10:29:02Z","timestamp":1585650542000},"page":"381-395","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-5","source":"Crossref","is-referenced-by-count":59,"title":["Androgen signaling pathways driving reproductive and metabolic phenotypes in a PCOS mouse model"],"prefix":"10.1530","volume":"245","author":[{"given":"Ali","family":"Aflatounian","sequence":"first","affiliation":[{"name":"1Fertility and Research Centre, School of Women\u2019s & Children\u2019s Health, University of New South Wales Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa C","family":"Edwards","sequence":"additional","affiliation":[{"name":"1Fertility and Research Centre, School of Women\u2019s & Children\u2019s Health, University of New South Wales Sydney, New South Wales, Australia"},{"name":"2Andrology Laboratory, ANZAC Research Institute, University of Sydney, Concord Hospital, Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valentina","family":"Rodriguez Paris","sequence":"additional","affiliation":[{"name":"1Fertility and Research Centre, School of Women\u2019s & Children\u2019s Health, University of New South Wales Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J","family":"Bertoldo","sequence":"additional","affiliation":[{"name":"1Fertility and Research Centre, School of Women\u2019s & Children\u2019s Health, University of New South Wales Sydney, New South Wales, Australia"},{"name":"3Laboratory for Ageing Research, School of Medical Sciences, University of New South Wales Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reena","family":"Desai","sequence":"additional","affiliation":[{"name":"2Andrology Laboratory, ANZAC Research Institute, University of Sydney, Concord Hospital, Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert B","family":"Gilchrist","sequence":"additional","affiliation":[{"name":"1Fertility and Research Centre, School of Women\u2019s & Children\u2019s Health, University of New South Wales Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William L","family":"Ledger","sequence":"additional","affiliation":[{"name":"1Fertility and Research Centre, School of Women\u2019s & Children\u2019s Health, University of New South Wales Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David J","family":"Handelsman","sequence":"additional","affiliation":[{"name":"2Andrology Laboratory, ANZAC Research Institute, University of Sydney, Concord Hospital, Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirsty A","family":"Walters","sequence":"additional","affiliation":[{"name":"1Fertility and Research Centre, School of Women\u2019s & Children\u2019s Health, University of New South Wales Sydney, New South Wales, Australia"},{"name":"2Andrology Laboratory, ANZAC Research Institute, University of Sydney, Concord Hospital, Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","container-title":["Journal of Endocrinology"],"original-title":[],"link":[{"URL":"https:\/\/joe.bioscientifica.com\/view\/journals\/joe\/245\/3\/JOE-19-0530.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/joe.bioscientifica.com\/downloadpdf\/journals\/joe\/245\/3\/JOE-19-0530.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T13:57:02Z","timestamp":1784555822000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.bioscientifica.com\/joe\/article\/245\/3\/381-395\/5331"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,6]]},"references-count":0,"journal-issue":{"issue":"3"},"URL":"https:\/\/doi.org\/10.1530\/joe-19-0530","relation":{},"ISSN":["0022-0795","1479-6805"],"issn-type":[{"value":"0022-0795","type":"print"},{"value":"1479-6805","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,6]]}}}
