Testosterone concentrations in the seminal plasma of cocks ranged from 0.46 to 5.05 ng/ml and were substantially lower than in blood plasma. No significant variation was noted in seminal plasma testosterone concentrations during the light phase of the day, whereas the concentration in blood declined over this period. Spermatozoal concentration and seminal testosterone decreased in the third sample of the semen collected sequentially at 3 h intervals. Testosterone concentrations in seminal plasma (1.57 +/- 0.17 ng/ml) and in the semen from the ductus deferens (1.34 +/- 0.24 ng/ml) were not significantly different.
公鸡精液中睾酮浓度范围为0.46至5.05纳克/毫升，显著低于血浆中的浓度。在白天的光照阶段，精液中睾酮浓度没有显著变化，而血浆中的浓度在此期间下降。每隔3小时依次采集的精液第三个样本中，精子浓度和精液睾酮含量降低。精液中睾酮浓度（1.57±0.17纳克/毫升）与来自输精管的精液中睾酮浓度（1.34±0.24纳克/毫升）没有显著差异。
