摘要
目的:观察精囊腺摘除后SD大鼠的性反应,分析精囊分泌功能对性功能的影响。方法:实验组采用普通的外科手术将雄性大鼠精囊腺摘除,对照组暴露两侧精囊腺后即行缝合。在对雌鼠给予药物催情的情况下,分两组进行交配,观察两组雄鼠爬高潜伏期、爬高总次数、插入潜伏期等性功能相关指标,并进行统计学分析。结果:与对照组相比,SD大鼠在摘除精囊腺后,爬高潜伏期、插入潜伏期延长,2h内爬高总次数、2h内插入总次数及有射精活动鼠数减少,两组间的差异性具有极显著性;两组的命中率比较,P<0.05,其差异具有显著性。结论:精囊腺摘除后,大鼠的性功能显著降低,说明精囊腺对维持大鼠的正常性功能具有重要影响。
Objective： To observe the influence of excising seminal vesicle on male SD rat＇s sexual behavior and analyze the effect of secretory function of seminal vesicle on rat＇s sexual function. Methods：Experimental group SD rats were surgically removed their seminal vesicles while control group underwent pseudo-operation. Then, two groups of male rats copulated with female rats philtred in advance. Indexes of sexual function such as mount latency,mount frequency and intromission latency were observed and recorded and statistically analyzed. Results：Compared with control group, SD rats removed of seminal vesicles prolonged their mount latency, intromission latency and decreased their mount frequency in 2 hours. The differences between two groups were statistically significant （P 〈 0.05）. Conclusion：The removal of rats＇seminal vesicle is associated with decreased sexual behaviors,which suggests that the existence of seminal vesicle is obviously important to keep the normal sexual function.
