Struktur anatomi dan histologi organ reproduksi jantan garangan jawa (herpestes javanicus) abstrak garangan jawa (herpestes javanicus) merupakan salah satu mamalia karnivora yang menarik untuk dikaji terkait karakteristik organ reproduksinya. organ reproduksi jantan berperan penting dalam proses perkembangbiakan dan keberlangsungan suatu spesies. secara umum, struktur organ reproduksi mamalia menunjukkan kesamaan, namun terdapat variasi dalam bentuk, ukuran, dan pola histologis, terutama pada kelompok karnivora. penelitian ini bertujuan untuk mengetahui struktur anatomi, histologi, dan histomorfometri organ reproduksi jantan garangan jawa. penelitian dilakukan secara eksploratif menggunakan tiga ekor garangan jawa jantan dewasa. pengamatan anatomi dilakukan secara makroskopis, sedangkan pengamatan histologi dan histomorfometri dilakukan pada preparat jaringan dengan pewarnaan hematoksilin-eosin. hasil penelitian menunjukkan bahwa organ reproduksi jantan garangan jawa terdiri atas testis, epididymis, ductus deferens, glandula accessoria yaitu glandula prostat dan bulbourethralis (tidak terdapat glandula vesicula seminalis), dan penis yang mengandung os penis, yaitu pada bagian corpus penis hingga glans penis secara histologis, testis tersusun atas tubulus seminiferus dengan diameter rata-rata 164,45 μm ± 13,17 μm dan ketebalan epitel 54,19 μm ± 4,54 μm. epididymis menunjukkan peningkatan diameter duktus dari caput, corpus, dan cauda secara berturut-turut, 192,61 μm ± 19,43 μm; 220,61 μm ± 28,65 μm; dan 417,52 μm ± 44,88 μm disertai peningkatan ketebalan epitel ductus pada bagian caput (36,93 μm ± 5,83 μm) ke corpus (37,12 μm ± 3,37 μm) dan menurun pada bagian cauda (21,04 μm ± 2,19 μm). dapat disimpulkan bahwa organ reproduksi jantan garangan jawa secara umum memiliki karakteristik yang mirip dengan hewan karnivora jantan lainnya namun secara spesifik tidak memiliki glandula vesicula seminalis dan memiliki os penis pada corpus penis hingga glans penis. kata kunci: garangan jawa, organ reproduksi, jantan, anatomi, histologi

ANATOMICAL AND HISTOLOGICAL STRUCTURE OF THE MALE REPRODUCTIVE ORGANS OF THE JAVAN MONGOOSE (Herpestes javanicus) ABSTRACT The Javan mongoose (Herpestes javanicus) is one of the carnivorous mammals that is interesting to study in relation to the characteristics of its reproductive organs. The male reproductive organs play an important role in the reproductive process and the continuity of a species. In general, the structure of mammalian reproductive organs shows similarities; however, variations exist in their shape, size, and histological patterns, particularly among carnivores. This study aimed to determine the anatomical, histological, and histomorphometric structures of the male reproductive organs of the Javan mongoose. The research was conducted using an exploratory approach involving three adult male Javan mongooses. Anatomical observations were carried out macroscopically, while histological and histomorphometric observations were performed on tissue preparations stained with hematoxylin–eosin. The results showed that the male reproductive organs of the Javan mongoose consist of the testis, epididymis, ductus deferens, and accessory glands, namely the prostat and bulbourethral (with no vesicula seminalis present), as well as the penis, which contains an os penis extending from the corpus penis to the glans penis. Histologically, the testis are composed of tubulus seminiferus with an average diameter of 164.45μm ± 13.17μm and an epithelial thickness of 54.19μm ± 4.54μm. The epididymis showed an increase in duct diameter from the caput, corpus, and cauda, measuring 192.61μm ± 19.43μm; 220.61μm ± 28.65μm; and 417.52μm ± 44.88μm, respectively. The epithelial thickness of the duct increased from the caput (36.93μm ± 5.83μm) to the corpus (37.12μm ± 3.37μm) and decreased in the cauda (21.04μm ± 2.19μm). In conclusion, the male reproductive organs of the Javan mongoose generally exhibit characteristics similar to those of other male carnivores, however, they specifically lack vesicula seminalis and possess an os penis extending from the corpus penis to the glans penis.
