Abstract

Sialic acid levels were determined in spermatozoa and seminal plasma of 47 semen samples divided into two groups according to sperm counts. Group 1, up to 40 x 10(6) sperm/ml seminal fluid and group 2, above 40 x 10(6) sperm/ml seminal fluid. The content of sialic acid in spermatozoa ranged from 4.4-28.1 micrograms/10(8) spermatozoa and from 70-95 mg/100 ml seminal plasma. Sialic acid was significantly higher in sperm and lower in seminal plasma of group 1 as compared to group 2. The lower content of sialic acid in seminal plasma might have a deteriorating effect on structural integrity of sperm.

摘要

根据精子计数，将47份精液样本分为两组，测定了精子和精浆中的唾液酸水平。第1组，精液中精子含量高达40×10⁶/ml，第2组，精液中精子含量高于40×10⁶/ml。精子中唾液酸含量范围为4.4 - 28.1微克/10⁸个精子，精浆中唾液酸含量范围为70 - 95毫克/100毫升。与第2组相比，第1组精子中的唾液酸含量显著更高，精浆中的唾液酸含量更低。精浆中较低的唾液酸含量可能会对精子的结构完整性产生不良影响。
