This paper reveals that exposure to the pervasive oestrogenic pollutant 17\u0251-ethinylestradiol does not impact female reproduction in a nonmodel viviparous fish.<\/jats:p>\n                  <jats:p>Abstract: Pharmaceuticals are fast becoming a major source of environmental pollution. Many pharmaceuticals are endocrine disruptors and can thus interfere with the endocrine system of exposed organisms, leading to a suite of behavioural and physiological alterations. While numerous studies have shown that exposure to pharmaceutical contaminants can disrupt the reproductive ecology of oviparous fishes, far less attention has been given to understanding the impacts on viviparous fishes, despite their ecological and evolutionary importance. Here, we investigated the impacts of the pharmaceutical contaminant 17\u0251-ethinylestradiol (EE2) on the reproductive biology of a marine livebearer, the Southern crested weedfish (Cristiceps australis). Adult weedfish were exposed to one of three nominal concentrations of EE2 (0, 30, and 300\u2009ng\/L) for 14\u2009days. We then assessed the impacts of exposure on morphology of both sexes, and female gametogenesis. In doing so, we found no differences in the body length, weight, or condition of fish between treatment groups. We additionally found no differences in gonadosomatic index or gametogenesis between exposed and unexposed females. In contrast to reports in other taxa, our findings suggest that short-term exposure to EE2 does not produce detectable effects on weedfish growth and reproduction. However, the extent to which exposure duration influences these responses is unknown. Ultimately, these results emphasize the importance of assessing the effects of EE2 on a diverse range of organisms if we are to gain a more comprehensive understanding of its ecological impacts.<\/jats:p>","DOI":"10.1093\/reprod\/xaag062","type":"journal-article","created":{"date-parts":[[2026,5,14]],"date-time":"2026-05-14T12:02:57Z","timestamp":1778760177000},"source":"Crossref","is-referenced-by-count":0,"title":["Ovarian responses to 17\u0251-ethinylestradiol in a marine livebearer, the Southern crested weedfish"],"prefix":"10.1093","volume":"171","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-4949-1405","authenticated-orcid":false,"given":"Rhiannon V","family":"Eastment","sequence":"first","affiliation":[{"name":"School of Biological Sciences, Monash University , Melbourne,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiho","family":"Ozeki","sequence":"additional","affiliation":[{"name":"School of Biological Sciences, Monash University , Melbourne,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-7947-6473","authenticated-orcid":false,"given":"Jack L","family":"Manera","sequence":"additional","affiliation":[{"name":"School of Biological Sciences, Monash University , Melbourne,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew D","family":"McGee","sequence":"additional","affiliation":[{"name":"School of Biological Sciences, Monash University , Melbourne,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5765-9699","authenticated-orcid":false,"given":"Camilla M","family":"Whittington","sequence":"additional","affiliation":[{"name":"School of Life and Environmental Sciences, The University of Sydney , Sydney,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9352-6500","authenticated-orcid":false,"given":"Bob B M","family":"Wong","sequence":"additional","affiliation":[{"name":"School of Biological Sciences, Monash University , Melbourne,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,5,16]]},"reference":[{"key":"2026061800214020000_xaag062-B1","doi-asserted-by":"publisher","first-page":"2","DOI":"10.23880\/act-16000240","article-title":"Effect of 17\u03b1-ethinylestradiol on the intestinal calcium carbonate excretion rate of Yellow Fin Sea Bream (Acanthopagrus latus)","volume":"7","author":"Al-Jandal","year":"2022","journal-title":"Advances in Clinical Toxicology"},{"key":"2026061800214020000_xaag062-B2","doi-asserted-by":"publisher","first-page":"469","DOI":"10.1093\/ilar.45.4.469","article-title":"Small fish models for identifying and assessing the effects of endocrine-disrupting chemicals","volume":"45","author":"Ankley","year":"2004","journal-title":"ILAR Journal"},{"key":"2026061800214020000_xaag062-B3","doi-asserted-by":"publisher","first-page":"104","DOI":"10.1016\/j.envint.2014.04.011","article-title":"Occurrence of 17\u03b1-ethynylestradiol (EE2) in the environment and effect on exposed biota: A review","volume":"69","author":"Aris","year":"2014","journal-title":"Environment International"},{"key":"2026061800214020000_xaag062-B4","doi-asserted-by":"publisher","first-page":"366","DOI":"10.1016\/j.chemosphere.2015.08.078","article-title":"Reproductive effects in fathead minnows (Pimphales promelas) following a 21 d exposure to 17\u03b1-ethinylestradiol","volume":"144","author":"Armstrong","year":"2016","journal-title":"Chemosphere"},{"key":"2026061800214020000_xaag062-B5","doi-asserted-by":"publisher","first-page":"20130569","DOI":"10.1098\/rstb.2013.0569","article-title":"Medicating the environment: Assessing risks of pharmaceuticals to wildlife and ecosystems","volume":"369","author":"Arnold","year":"2014","journal-title":"Philosophical Transactions of the Royal Society of London.
