The authors made a detailed clinical analysis of 119 stabilized total paraplegics in order to define, as precisely as possible, the limits of the medullary segment which, for each patient, had lost all its functional value. The relationships between the affected segments and the sexual capabilities of these patients show that the segment must: --exclude the sacral spinal cord if reflex erections are to occur; --underly Th. IX at least, or better still Th. XI, for psychogenic turgescence to appear; the efferent pathways seem therefore, to emerge from the cord quite close to the level which receives testicular afferent pathways; --underly or overly Th. XII, L I, and L II for at least the greater part, for emission of sperm to occur; a true abrupt ejaculation probably requires the complementary integrity of the sacral spinal cord.
作者对119例病情稳定的全瘫患者进行了详细的临床分析，以便尽可能精确地确定对每位患者而言已丧失所有功能价值的脊髓节段范围。这些患者受影响节段与性功能之间的关系表明，该节段必须：——若要出现反射性勃起，必须排除骶髓；——至少在胸9以下，最好在胸11以下，才会出现精神性勃起；因此，传出通路似乎在离接受睾丸传入通路的水平很近的脊髓节段发出；——至少大部分在胸12、腰1和腰2以下，才会发生射精；真正的突发性射精可能需要骶髓的完整配合。
