We consider over seventy references spanning from 1965 to 2020, with the majority of work being done in the past twenty years. Knowledge of the reproductive tract and reproductive technologies is critical to the conservation and preservation of these species. Although all three animals had similarities in their anatomy, such as no overt scrotums and testes located intra-abdominally in the inguinal region, some had unique features\u2014for example, the agouti and the paca had penile spines, and two lateral penile cartilages. High spermatogenic efficiency was noted in the agouti and the paca, making them good candidates for increasing their reproductive performance in conservation programs. A review of the literature has shown that there is increasing work taking place on the reproductive technologies used in these animals; however, a lot of work is still lacking, as, to the author\u2019s knowledge, standard protocols and artificial insemination procedures are yet to be established.<\/jats:p>","DOI":"10.3390\/ani12010034","type":"journal-article","created":{"date-parts":[[2021,12,24]],"date-time":"2021-12-24T08:38:46Z","timestamp":1640335126000},"page":"34","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Reproductive Technologies Used in Male Neo-Tropical Hystricomorphic Rodents"],"prefix":"10.3390","volume":"12","author":[{"given":"Kavita Ranjeeta","family":"Lall","sequence":"first","affiliation":[{"name":"Department of Food Production (DFP), Faculty of Food and Agriculture (FFA), University of the West Indies (UWI), St. Augustine Campus, St. Augustine 999183, Trinidad and Tobago"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1260-7606","authenticated-orcid":false,"given":"Kegan Romelle","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Food Production (DFP), Faculty of Food and Agriculture (FFA), University of the West Indies (UWI), St. Augustine Campus, St. Augustine 999183, Trinidad and Tobago"},{"name":"Department of Basic Veterinary Sciences (DBVS), School of Veterinary Medicine (SVM), Faculty of Medical Sciences (FMS), University of the West Indies (UWI), St. Augustine Campus, St. Augustine 999183, Trinidad and Tobago"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary Wayne","family":"Garcia","sequence":"additional","affiliation":[{"name":"Department of Food Production (DFP), Faculty of Food and Agriculture (FFA), University of the West Indies (UWI), St. Augustine Campus, St. Augustine 999183, Trinidad and Tobago"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"95","DOI":"10.1258\/002367767781035521","article-title":"The Care and Management of Laboratory Hystricomorph Rodents","volume":"1","author":"Weir","year":"1976","journal-title":"Lab.
