Sperm quality is a very important population survival factor, which can be influenced by the level of male's genetic diversity and can influence reproduction effectiveness, what may be crucial in terms of decision about local, endangered population protection plans. Thus, we analysed if heterozygosity and age influence sperm quality in the engendered European capercaillie (Tetrao urogallus) population in Polish breeding stations. Obtained results showed no relationship between normal sperm morphology and heterozygosity, as well as age and sperm morphology, but it was shown that both high and low level of heterozygosity significantly influenced the percentage of abnormal sperm. Thus, heterozygosity level can be a useful tool for population reproduction potential prediction, however, further research on how those abnormalities influence fertilization process are needed.
精子质量是一个非常重要的种群生存因素，它可以受到男性遗传多样性水平的影响，并可以影响繁殖效果，这对于地方濒危种群保护计划的决策可能至关重要。因此，我们分析了波兰繁殖站中产生的欧洲松鸡（Tetrao urogallus）种群的杂合度和年龄是否影响精子质量。结果表明，正常精子形态与杂合度以及年龄与精子形态之间没有关系，但表明高杂合度和低杂合度都会显著影响异常精子的比例。因此，杂合度水平可以作为预测种群繁殖潜力的有用工具，但是需要进一步研究这些异常如何影响受精过程。
