Assisted reproductive technologies, including semen preservation and artificial insemination (AI), are vital for conservation efforts. Although the results are controversial, it has been reported that antioxidants, such as catalase, play an important role in protecting against oxidative damage caused by reactive oxygen species during short\u2010 and long\u2010term sperm storage. This study evaluated the protective effects of catalase (200\u2009IU\/mL) on stored\/frozen\u2010thawed capercaillie sperm. The possible protective or harmful effect of catalase on fertilizing ability was assessed after AI with fresh and stored semen. Results indicated that catalase had no significant effect on sperm motility, viability, or DNA integrity after liquid storage or freezing\/thawing. Fertility rates decreased sharply after semen storage for 6\u2009h at 5\u00b0C even in the presence of catalase. Catalase\u2010treated samples maintained similar fertility rates to controls. The study also provided the first evidence of sperm storage duration within female capercaillies, which lasted up to 21 days. These findings underscore the challenges of semen preservation in wild species and highlight the need for further exploration of alternative antioxidants to optimize storage media.\n                  <\/jats:p>","DOI":"10.1002\/zoo.70056","type":"journal-article","created":{"date-parts":[[2026,3,14]],"date-time":"2026-03-14T09:20:20Z","timestamp":1773480020000},"page":"307-315","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Catalase Effect on Sperm Storage and Fertilization Capacity of Capercaillie (\n                    <i>Tetrao urogallus<\/i>\n                    )"],"prefix":"10.1002","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3142-9382","authenticated-orcid":false,"given":"Emma","family":"O'Brien","sequence":"first","affiliation":[{"name":"Centro de Cr\u00eda del Urogallo de Valsemana, Consejer\u00eda de Medio Ambiente, Vivienda y Ordenaci\u00f3n del Territorio, Junta de Castilla y Le\u00f3n Valsemana Le\u00f3n Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexia Siegmund","family":"Sabater","sequence":"additional","affiliation":[{"name":"Departamento de Reproducci\u00f3n Animal INIA\u2010CSIC Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6679-485X","authenticated-orcid":false,"given":"Adolfo","family":"Toledano\u2010D\u00edaz","sequence":"additional","affiliation":[{"name":"Departamento de Reproducci\u00f3n Animal INIA\u2010CSIC Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Casta\u00f1o","sequence":"additional","affiliation":[{"name":"Departamento de Reproducci\u00f3n Animal INIA\u2010CSIC Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ram\u00f3n","family":"Balsera","sequence":"additional","affiliation":[{"name":"Servicio de Vigilancia y Control de la Biodiversidad, Direcci\u00f3n General de Planificaci\u00f3n Agraria Oviedo Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Centro de Recuperaci\u00f3n de Fauna Silvestre de Sobrescobio, Direcci\u00f3n General de Planificaci\u00f3n Agraria Oviedo Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"de Pedro Aguilar","sequence":"additional","affiliation":[{"name":"Centro de Cr\u00eda del Urogallo de Valsemana, Consejer\u00eda de Medio Ambiente, Vivienda y Ordenaci\u00f3n del Territorio, Junta de Castilla y Le\u00f3n Valsemana Le\u00f3n Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Cubero","sequence":"additional","affiliation":[{"name":"Direcci\u00f3n General de Patrimonio Natural y Pol\u00edtica Forestal, Junta de Castilla y Le\u00f3n Valladolid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ewa","family":"\u0141ukaszewicz","sequence":"additional","affiliation":[{"name":"Division of Poultry Breeding, Institute of Animal Breeding Wroc\u0142aw University of Environmental and Life Sciences Wroc\u0142aw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5551-8120","authenticated-orcid":false,"given":"Juli\u00e1n","family":"Santiago\u2010Moreno","sequence":"additional","affiliation":[{"name":"Departamento de Reproducci\u00f3n Animal INIA\u2010CSIC Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,14]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10344-015-0929-1"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cryobiol.2015.03.001"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1530\/jrf.0.0830873"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.5772\/54918"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/00071668.2024.2394185"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1017\/S175173110700081X"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.3382\/ps.0160019"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1530\/jrf.0.0640259"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10592-023-01567-6"},{"key":"e_1_2_10_11_1","volume-title":"Reproduction in Poultry","author":"Etches R.
