The general features of the ovary of the coypu older than 6\u2009months are similar to those described for other hystricomorphs. The objective of this research was to expand the qualitative and quantitative characterization of the follicular typology of coypu at sexual maturity. We worked with 36 ovaries from females in different stages of the oestrous cycle. The follicles were analysed based on qualitative and quantitative characteristics, such as their size (mean follicular diameter and number of granulosa cells), size of each oocyte and its nucleus, presence of zona pellucida, antrum, and theca. Six follicular types were established, subdivided into 12 subtypes. Establishing this follicular typology in a South American species advances comparative studies. Additionally, it enables a deeper analysis of follicular development across different species.\n                  <\/jats:p>","DOI":"10.1111\/ahe.70131","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T13:15:06Z","timestamp":1779369306000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ovarian Follicular Typology in Coypu (\n                    <scp>\n                      <i>Myocastor coypus bonariensis<\/i>\n                    <\/scp>\n                    )"],"prefix":"10.1111","volume":"55","author":[{"given":"Felipe Antonio","family":"Eduardo","sequence":"first","affiliation":[{"name":"Universidad Nacional del Centro de la Provincia de Buenos Aires Facultad de Ciencias Veterinarias, Centro de Investigaciones Biol\u00f3gicas, Laboratorio de Histolog\u00eda y Embriolog\u00eda  Buenos Aires Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Killian Marcelo","family":"Pablo","sequence":"additional","affiliation":[{"name":"Universidad de Buenos Aires Facultad de Ciencias Veterinarias, C\u00e1tedra de Histolog\u00eda y Embriolog\u00eda  Buenos Aires Argentina"},{"name":"Universidad de Buenos Aires, Facultad de Ciencias Veterinarias, Instituto de Investigaci\u00f3n y Tecnolog\u00eda en Reproducci\u00f3n Animal (INITRA)  Buenos Aires Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lombardo Daniel","family":"Marcelo","sequence":"additional","affiliation":[{"name":"Universidad de Buenos Aires Facultad de Ciencias Veterinarias, C\u00e1tedra de Histolog\u00eda y Embriolog\u00eda  Buenos Aires Argentina"},{"name":"Universidad de Buenos Aires, Facultad de Ciencias Veterinarias, Instituto de Investigaci\u00f3n y Tecnolog\u00eda en Reproducci\u00f3n Animal (INITRA)  Buenos Aires Argentina"},{"name":"Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET)  Buenos Aires Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,21]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"Acta de Bienestar Animal.2002.\u201cFacultad de Ciencias Veterinarias Universidad Nacional del Centro de la Provincia de Buenos Aires.\u201dhttp:\/\/www.vet.unicen.edu.ar."},{"key":"e_1_2_8_3_1","first-page":"55","article-title":"Estudo Morfol\u00f3gico e Morfom\u00e9trico do Ov\u00e1rio de Cutias (Dasyprocta aguti, Linnaeus, 1766)","volume":"40","author":"Almeyda M.
