The ionic composition of human prostatic fluid varied greatly between individuals, reflecting the secretory activity of the gland and the presence or absence of prostatic inflammatory disease. In normal prostatic fluid the major anion was citrate, while chloride concentrations were lower. Their counterions were mainly sodium and potassium, together with calcium, magnesium and zinc. Prostatic secretions from men with prostatitis comprised mainly sodium and chloride. The electrolytes were closely correlated to each other (except for sodium, which was essentially invariant at about 145 nm). The molar changes per mole of citrate were about 0.52, potassium; -0.53, chloride; 0.17, calcium; 0.14, magnesium; and 0.09, zinc. The pH was also associated with citrate, decreasing from 8.0 to 6.2 as the citrate increased. These various ionic changes can be explained as responses to citrate secretion, without the need to propose specific transport mechanisms for the other ions measured. The marked effect of prostatic inflammation on the composition of prostatic fluid can be seen as being due mainly to decreased secretion rather than active modification.
人类前列腺液的离子组成在个体之间差异很大，这反映了前列腺的分泌活动以及前列腺炎症疾病的有无。在正常前列腺液中，主要阴离子是柠檬酸盐，而氯离子浓度较低。它们的抗衡离子主要是钠和钾，还有钙、镁和锌。前列腺炎患者的前列腺分泌物主要由钠和氯组成。电解质之间密切相关（钠除外，其在约145纳摩尔时基本不变）。每摩尔柠檬酸盐的摩尔变化约为：钾0.52；氯-0.53；钙0.17；镁0.14；锌0.09。pH值也与柠檬酸盐有关，随着柠檬酸盐增加，pH值从8.0降至6.2。这些各种离子变化可以解释为对柠檬酸盐分泌的反应，而无需为所测量的其他离子提出特定的转运机制。前列腺炎症对前列腺液成分的显著影响主要可归因于分泌减少而非主动改变。
