The prostatic fraction of seminal plasma contains components that are involved in the process of transforming fructose into glucose. If a positive correlation can be found between the slope of the decrease of fructose (estimated to be between 30 minutes and 5 hours) and the sperm count, with at the same time the maintenance of a relatively constant glucose level, then we have been able to demonstrate that glucose is more efficient than fructose to keep spermatozoa mobile. The enzyme process involved in transforming fructose into glucose may thus act to maintain definite glyspermia with a maximum value of 1.8 g/l. Aspermia in some circumstances then can be related to the absence or poor function of the transformation process and thus with the absence or decrease in prostatic secretion.
精浆中的前列腺部分含有参与将果糖转化为葡萄糖过程的成分。如果在果糖减少的斜率（估计在30分钟至5小时之间）与精子数量之间能发现正相关，同时葡萄糖水平保持相对恒定，那么我们就能证明葡萄糖在保持精子活力方面比果糖更有效。将果糖转化为葡萄糖所涉及的酶促过程可能因此起到维持特定血糖水平的作用，最大值为1.8克/升。在某些情况下，无精症可能与转化过程的缺失或功能不良有关，进而与前列腺分泌的缺失或减少有关。
