大鼠及大多数哺乳动物的睾网有3个部分:睾丸内、白膜内及睾丸外。大鼠的睾丸内睾网基本上是一个扁平囊,其长度约10mm。睾丸内睾网与白膜内睾网相连,白膜内睾网再延伸成睾丸外睾网,后者由互相贯通的3～9个腔组成,每个腔与一根输出管相连而接至附睾。收集睾网液的传统方法是在结扎输出管后一定时间,用具有侧孔的带针塑胶导管(外径0.5mm)直接穿刺白膜而进入睾丸内睾网。此法有以下缺点:导管插入位置不易掌握,插管时局部损伤较大,收集到的睾网液有时混有少量血液或组织液,影响数据的准确性。国外也有人指出,本法常因误差所测得数据波
The testis of rats and most mammals has three parts: the testis, the perilymph and the testis. The testicular intraperitoneal mesh of a rat is essentially a flattened capsule with a length of about 10 mm. Testicular testis network connected to the white membrane within the testicular network, the testicular network in the white membrane and then extended into the testis outside the testis network, which consists of interpenetrating 3 to 9 cavities, each cavity connected to an output tube connected to Epididymis. The traditional method of collecting the testis fluid is to insert the testicular endometriosis net directly with a plastic catheter with a lateral hole (0.5 mm in outside diameter) punctuating the white membrane immediately after the output tube is ligated. This method has the following shortcomings: the catheter insertion position is not easy to grasp, local injury when intubation larger, collected fluid collected sometimes mixed with a small amount of blood or tissue fluid, affecting the accuracy of the data. Someone abroad also pointed out that this law is often the result of error data wave
