Seminal hyperviscosity has been shown to be associated with male infertility. The aim of this study was to assess the prevalence of hyperviscosity in semen of Malawian males seeking infertility treatment.
A total of 120 men visiting our laboratory for fertility assessment donated semen samples. The semen samples were assessed for hyperviscosity, volume, concentration, total motility, progressive motility, viability, and morphology.
Out of the 120 samples analyzed, 34 samples were hyperviscous representing 28.3%. No significant statistical difference in semen volume between samples with normal viscosity compared to those with hyperviscosity (p>0.05). Sperm concentration, progressive motility, total motility, viability, and normal morphology were significantly higher in the normal viscosity group when compared to the abnormal viscocity group (p<0.05).
Hyperviscosity affects a significant number of men in Malawi and may be the cause of decreased fertility as it was associated with poor sperm concentration, total motility, progressive motility, viability, and morphology.
精液高黏稠度与男性不育有关。本研究旨在评估在马拉维寻求不孕治疗的男性精液中高黏稠度的流行率。
共有 120 名男性在我们的实验室接受生育评估，捐献了精液样本。对精液样本进行高黏稠度、体积、浓度、总活力、前向运动活力、活力和形态学评估。
在分析的 120 个样本中，34 个样本为高黏稠度，占 28.3%。正常黏度样本与高黏度样本的精液体积无显著统计学差异（p>0.05）。与异常黏度组相比，正常黏度组的精子浓度、前向运动活力、总活力、活力和正常形态均显著更高（p<0.05）。
高黏稠度影响了马拉维相当数量的男性，可能是导致生育能力下降的原因，因为它与精子浓度、总活力、前向运动活力、活力和形态学降低有关。
