Although active spermatogenesis occurs throughout the year in the male European badger Meles meles L., seasonal fluctuations of testicular activity were observed. The present study compared the pattern of luteinizing hormone (LH) and testosterone (T) secretions throughout the annual cycle. LH secretion was investigated by means of a heterologous radioimmunoassay using anti-ovine LH beta antiserum and canine reference standard. Seasonal and nycthemeral changes in LH and T secretions were observed. During the year a period of maximal values for both hormones is well correlated with the breeding. Moreover, episodic LH releases occurs during the period of minimal testosterone values, indicating resumption of hypothalamo-pituitary activity well before the breeding period.
尽管雄性欧洲獾（Meles meles L.）全年都有活跃的精子发生，但仍观察到睾丸活动存在季节性波动。本研究比较了全年周期中促黄体生成素（LH）和睾酮（T）的分泌模式。采用使用抗羊LHβ抗血清和犬参考标准品的异源放射免疫分析法研究LH分泌。观察到LH和T分泌的季节性和昼夜变化。在一年中，两种激素的最大值时期与繁殖期密切相关。此外，在睾酮值最低的时期会出现LH的间歇性释放，这表明下丘脑-垂体活动在繁殖期之前就已恢复。
