...Danny Wotherspoon; Shelley Burgin Testis volume is generally correlated with sperm production. Their size is, therefore, considered informative, and is widely used as a surrogate for reproductive ability in a range of species. Gonadal abnormalities that influence adult reproductive function...

...S Johnston; C Rumph; M Lucht; D Stenzel; V Nicolson; D Blyde; T Keeley Despite its vulnerable conservation status there is scant information on male Greater Bilby Macrotis lagotis reproduction. Observations of gross anatomy revealed a testis to body weight ratio of 0.08 - 0.'7% (n = 4...

... become sexually mature at a SVL of approximately 42 mm and 46 mm. respectively. In the Sturt sample, testis size is much larger in spring that in autumn. In the species as a whole, reproduction occurs between early spring and mid-autumn. Females with yolking follicles or oviducal eggs range in size from...

... in tall open forest at Cam- banrille about 90 km north-east of Melbourne. Descrip- tions of habitat and climate can be found in Smith (1982, 1984) and Craig (1985). The following measurements were made for each animal at time of capture: mass, body length, head-body length, pes length, testis length...

.... RESULTS Gross examination of the gonads of the recently metamorphosed frogs revealed two different shapes to the organ: a compact ovoid; and a more elongate and slightly convoluted ribbon. On the basis of the size and shape of the mature gonad, the former shape was interpreted as a testis and the latter...

...% of the total ovary weight. The testes are whitish in colour and are divided also for their entire length. One testis is longer than the other. The testes may be very large, reaching up to 55% of the length of the fish. For example, in one fish 96mm long and weighing 7.0g, one testis weighed 1.08g and was 52mm...
