The purpose of this study was to evaluate this organ histologically and to determine the time of development of the UGP in Black Rockfish. Twelve adult males, three adult females and around 500 juveniles were used in the experiment. The juveniles were divided into normal developmental and androgen groups. The androgen group was exposed to methyltestosterone (100\u2009\u03bcg\/L) for 2\u2009h daily for 38 days. Samples (\n                    <jats:italic>N<\/jats:italic>\n                    \u2009=\u200910 per sampling) were randomly selected for analysis every 5 days from 30 to 116 days after birth. Parameters assessed included the type of epithelium, composition of connective tissue, muscular tissue, and the timing of UGP development. Differences in these parameters between normal developmental and androgen groups were evaluated. The results indicated that the UGP of the adult fish contains the sperm duct and ureter, which have the function of transporting sperm and urine, respectively. The androgen\u2010treated juvenile fish developed the UGP earlier than the normal development group. This study provides a reference for understanding the external genitalia of other viviparous fishes by studying the UGP of the male Black Rockfish.\n                  <\/jats:p>","DOI":"10.1002\/jmor.21534","type":"journal-article","created":{"date-parts":[[2022,11,14]],"date-time":"2022-11-14T03:00:16Z","timestamp":1668394816000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Morphology of the urogenital papilla of the male marine teleost Black Rockfish,\n                    <i>Sebastes schlegelii<\/i>\n                    (Hilgendorf, 1880), and its role in internal fertilization"],"prefix":"10.1002","volume":"284","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7145-2125","authenticated-orcid":false,"given":"Tao","family":"Wang","sequence":"first","affiliation":[{"name":"School of Marine Science and Engineering Qingdao Agricultural University Qingdao China"},{"name":"CAS and Shandong Province Key Laboratory of Experimental Marine Biology, Center for Ocean Mega\u2010Science, Institute of Oceanology Chinese Academy of Sciences Qingdao China"},{"name":"Laboratory for Marine Biology and Biotechnology Qingdao National Laboratory for Marine Science and Technology Qingdao China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xueying","family":"Wang","sequence":"additional","affiliation":[{"name":"CAS and Shandong Province Key Laboratory of Experimental Marine Biology, Center for Ocean Mega\u2010Science, Institute of Oceanology Chinese Academy of Sciences Qingdao China"},{"name":"Laboratory for Marine Biology and Biotechnology Qingdao National Laboratory for Marine Science and Technology Qingdao China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Zhao","sequence":"additional","affiliation":[{"name":"CAS and Shandong Province Key Laboratory of Experimental Marine Biology, Center for Ocean Mega\u2010Science, Institute of Oceanology Chinese Academy of Sciences Qingdao China"},{"name":"Laboratory for Marine Biology and Biotechnology Qingdao National Laboratory for Marine Science and Technology Qingdao China"},{"name":"University of Chinese Academy of Sciences Beijing China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qinghua","family":"Liu","sequence":"additional","affiliation":[{"name":"CAS and Shandong Province Key Laboratory of Experimental Marine Biology, Center for Ocean Mega\u2010Science, Institute of Oceanology Chinese Academy of Sciences Qingdao China"},{"name":"Laboratory for Marine Biology and Biotechnology Qingdao National Laboratory for Marine Science and Technology Qingdao China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zongcheng","family":"Song","sequence":"additional","affiliation":[{"name":"Weihai Shenghang Aquatic Product Science and Technology Co.
