Catecholamine distribution in the adult rat testis was examined using a sensitive radioenzymatic method. Norepinephrine was present in the capsule and the interstitial fluid, in higher concentrations than dopamine, while in the interstitial cell preparations only norepinephrine was found. Epinephrine was undetectable in all testicular compartments investigated. No catecholamines were found in the seminiferous tubules. Testicular denervation caused a significant decrease in capsular catecholamines, confirming the neural origin of these amines.
使用灵敏的放射酶法检测成年大鼠睾丸中儿茶酚胺的分布。去甲肾上腺素存在于被膜和间质液中，其浓度高于多巴胺，而在间质细胞制剂中仅发现了去甲肾上腺素。在所研究的所有睾丸区域均未检测到肾上腺素。在生精小管中未发现儿茶酚胺。睾丸去神经支配导致被膜儿茶酚胺显著减少，证实了这些胺的神经来源。
