Therefore, production of high quality semen was restricted to the end of the spawning season and delayed for approximately 4 weeks in comparison to the control. At BPA exposure levels of 5.00 μg l<sup>−1</sup> only one of eight males gave semen of low quality (reduced semen mass, motility rate, and swimming velocity).<p>The percentage of ovulated females was similar for the control group and the groups exposed to estimated BPA concentrations of 1.75 and 2.40 μg l<sup>−1</sup>, whereas at 5.00 μg l<sup>−1</sup> BPA females did not ovulate during the investigation. While brown trout of the control group ovulated between the 28 October and 12 November, brown trout exposed to estimated BPA concentrations of 1.75 μg l<sup>−1</sup> BPA ovulated approximately 2 weeks later and brown trout exposed to 2.40 μg l<sup>−1</sup> BPA approximately 3 weeks later. Therefore, the tested BPA concentrations affected the percentage of ovulated females and the time point of ovulation. No effect was observed on the quality of eggs (egg mass, percentile mass increase during hardening, egg fertility).","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effect of bisphenol A on maturation and quality of semen and eggs in the brown trout, <i>Salmo trutta f. fario</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:12.047151","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"bisphenol A; brown trout; Salmo trutta f. fario; spermatozoa; eggs;motility; fertility","OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2020-10-16","DateCreate":"2005-11-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000233067100003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquatox.2005.08.004"},"refs":null,"anarec":{"AnaID":77769,"PubliDate":2005,"Pagination":"213-224","XtraPublOfAnaID":null,"ISBN":null,"Volume":"75","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42203,"SerRR":"Aquatic Toxicology.
