Electroejaculation of a variety of Australian marsupials was attempted in this study. The animals used were conscious, sedated, anaesthetized or recently shot. Electroejaculation proved to be a satisfactory means of obtaining seminal plasma but not spermatozoa. The largest volumes of seminal plasma were collected from animals shortly after death. Anaesthetized animals also provided useful volumes of seminal plasma but only insignificant amounts were obtained from conscious and sedated animals. Quantitative analyses of N-acetylglucosamine, glucose and anthronereactive material were made of deproteinized, deionized, water extracts of seminal plasma from electroejaculates obtained from wallabies and kangaroos shortly after death. The major seminal sugar of the three macropod species was N-acetylglucosamine and glucose was also present in quite large concentrations. These observations show that the pattern of sugars in the prostate gland of marsupials is reflected in the semen.
本研究尝试对多种澳大利亚有袋动物进行电射精。所用动物处于清醒、镇静、麻醉状态或刚被射杀。结果表明，电射精是获取精浆而非精子的一种令人满意的方法。刚死亡后不久的动物能采集到最大量的精浆。麻醉状态的动物也能提供一定量有用的精浆，但清醒和镇静状态的动物只能获得少量精浆。对从刚死亡后的小袋鼠和袋鼠电射精获取的精浆进行脱蛋白、去离子水提取后，对其中的N - 乙酰葡糖胺、葡萄糖和蒽酮反应性物质进行了定量分析。三种有袋类动物精浆中的主要糖类是N - 乙酰葡糖胺，葡萄糖也以相当高的浓度存在。这些观察结果表明，有袋动物前列腺中的糖类模式在精液中得到了体现。
