This animal is listed as \u2018vulnerable\u2019 on the International Union for Conservation of Nature's Red List of Threatened Species. Studies on the reproduction of this species are essential because of its peculiarities; however, there is a lack of information on its reproductive aspects and the biotechnologies that can be applied to it. Morphological and histopathological descriptions of the reproductive organs of <jats:styled-content style=\"fixed-case\"><jats:italic>Myrmecophaga tridactyla<\/jats:italic><\/jats:styled-content> are fundamental for determining the general characteristics that could improve our understanding of reproductive disorders in this species. Therefore, this study aimed to perform morphological and histochemical characterisation of the penis of <jats:styled-content style=\"fixed-case\"><jats:italic>Myrmecophaga tridactyla<\/jats:italic><\/jats:styled-content>. For this purpose, we collected six postmortem samples of giant anteater penises. The penis of the giant anteater has no foreskin, two erectile bodies, a paired corpora cavernosa, corpus spongiosum and urethra. Type I (red) and type III (yellow\u2010green) collagen fibres were distributed throughout the stroma and erectile bodies of the penis. Periodic acid\u2010Schiff (PAS)\u2010positive staining was observed in the epithelial cells at the base of the hair follicles, and immunohistochemical immunolabelling for androgen receptors (AR) and oestrogen receptors (ER) was detected in all cells of the transitional epithelium of the penile urethra. These findings suggest that penile urethra cells are sensitive to oestrogen and progesterone.<\/jats:p>","DOI":"10.1111\/ahe.70057","type":"journal-article","created":{"date-parts":[[2025,8,6]],"date-time":"2025-08-06T10:29:57Z","timestamp":1754476197000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Morphological, Histochemical and Immunohistochemical Characterisation of the Penis in Free\u2010Ranging Giant Anteaters (<i>Myrmecophaga tridactyla<\/i>)"],"prefix":"10.1111","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8153-2038","authenticated-orcid":false,"given":"Fernanda Barthelson Carvalho","family":"de Moura","sequence":"first","affiliation":[{"name":"School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victor Gustavo Santos","family":"M\u00f4ra","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences Paulista University (UNIP)  Bauru Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia Camargo","family":"Faraldo","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel Correa","family":"de Camargo","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Roberto","family":"Teixeira","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Valeria","family":"de Toledo Rodovalho","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences Paulista University (UNIP)  Bauru Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatiane Terumi Negr\u00e3o","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Antech Diagnostics, Mars Petcare Science and Diagnostics  Fountain Valley California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel Felipe Barrantes","family":"Murillo","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathobiology, College of Veterinary Medicine Oklahoma State University  Stillwater Oklahoma USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noeme Sousa","family":"Rocha","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences Paulista University (UNIP)  Bauru Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Eduardo","family":"Fonseca\u2010Alves","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"},{"name":"Institute of Health Sciences Paulista University (UNIP)  Bauru Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,8,6]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464\u2010410x.2010.09944.x"},{"issue":"2","key":"e_1_2_10_3_1","first-page":"41","article-title":"Topography of the Organs of the Pelvic Cavity and Macroscopic and Histologic Findings of the Sex Organs of a Male Giant Anteater (Myrmecophaga tridactyla) With Regard to Fertility","volume":"104","author":"Bartmann C.
