Lima ekor betina Kanguru Pohon Kelabu (Dendrologus inustus) dewasa dengan rata-rata umur 1-2,5 tahun, bobot badan 10,83 kg dan panjang tubuh 72,8 cm, dibedah memakai peralatan bedah dan diambil organ reproduksinya. Karakteristik organ reproduksi didokumentasikan dengan kamera digital, diukur dan ditimbang. Penelitian ini menggunakan metode studi eksperimen deskreptif dengan teknik studi kasus. Analisis data menggunakan statistik deskreptif dan korelasi bagi beberapa informasi yang dibutuhkan lalu ditampilkan dalam nilai rata-rata dan standar deviasi (SD). Hasil pengamatan diperoleh panjang organ reproduksi betina D.inustus berkisar 18,88 ± 0,78cm (kiri) dan 19,00 ± 0,78cm (kanan) dengan panjang ovarium berkisar 1cm (kiri/kanan) dengan berat berkisar 0,59 ± 0,85g (kiri) dan 1g (kanan). Diameter dan panjang tuba fallopi, cornu uteri, corpus uteri, dan cervix masing-masing adalah: 0,57 ± 0,01mm (kiri) dan 0,60 ± 0,01mm (kanan), dan 3,00 (kiri) dan 3,26 ± 0,18cm (kanan); 0,54 ± 0,02mm (kiri) dan 0,56 ± 0,02mm (kanan), dan 4cm (kiri) dan 4,8 ± 0,45cm (kanan); 1,16 ± 0,09mm (kiri) dan 1,3 ± 0,12mm (kanan), dan 1cm; 0,3mm (kiri/kanan) dan 3cm (kiri/kanan), sedangkan panjang vagina dan vulva berturut-turut adalah 4 dan 2 cm. Hasil studi menunjukkan bahwa bentuk dan model organ reproduksi D.inustus menyerupai organ betina mamalia umumnya, namun semua organ berjumlah dua dengan sekat yang tampak jelas serta ukurannya yang berbeda.

Five females of 1-2.5 years old Gray Tree Kangaroo (Dendrologus inustus), 10.83kg body weight and 72.8cm body length were dissected, then the reproductive organ were observed for morphology, length, and weight using digital camera, tape measured and scale. This study used experimental studies-descriptive case study technique, statistical analytic and correlation displayed in the average value and standard deviation (SD). The length of the female D.inustus reproductive organ was range 18.88 ± 0.78cm (left) and 19.00 ± 0.78cm (right), length of ovarian 1cm (left/right), and 0.59 ± 0.85g (left) and 1g (right) weight. Diameter and length of fallopian tube, uterine horn, corpus uteri, and cervical ware 0.57 ± 0.01mm (left) and 0.60 ± 0.01mm (right) and 3.00cm (left) and 3.26 ± 0.18cm (right); 0.54 ± 0.02mm (left) and 0.56 ± 0.02mm (right) and 4cm (left) and 4.8 ± 0.45cm (right); 1.16 ± 0.09mm (left) and 1.3 ± 0.12mm (right) and 1cm (left/right); 0.3mm (left/right) and 3cm (left/right), respectively. Length of vagina and vulva were 4 and 2cm, respectively. The result showed that shape and model D.inustus reproductive organs were similar with the mammalian female reproductive organs generally but all the organs have two parts which has evident partition as well as different sizes.
