Production of spermatozoa and secretion of rete testis fluid (RTF) in rams was assessed by a rete testis cannulating technique. Four breeds (Ile-de-France, Romanov, Préalpes du Sud and cross-breed Romanov) were studied throughout the year. Inhibitory effects of the cannulation process on spermatogenesis were observed for some animals. Between-breed differences were found in sperm concentration and flow rate of the RTF. The seasonal variations in the daily sperm production of the testis were more pronounced for Ile-de-France rams than for the other breeds. There was a seasonal variation in the flow rate of RTF in Ile-de-France rams, the minimum flow being in February (winter) and the maximum in August-September (autumn).
通过睾丸网插管技术评估了公羊精子的产生和睾丸网液（RTF）的分泌。全年研究了四个品种（法兰西岛、罗曼诺夫、南阿尔卑斯和罗曼诺夫杂交品种）。观察到插管过程对某些动物的精子发生有抑制作用。在精子浓度和RTF流速方面发现了品种间差异。法兰西岛公羊睾丸每日精子产量的季节性变化比其他品种更为明显。法兰西岛公羊的RTF流速存在季节性变化，最低流速在2月（冬季），最高流速在8月至9月（秋季）。
