The present study compared several rat sperm parameters in semen samples recovered from a natural uterine environment (i.e., intact estrous female) to those recovered from an artificially induced uterine environment (i.e., ovariectomized hormonally primed female). The sperm parameters measured were percent motile, percent exhibiting forward progressive motility, actual swimming speed, and linear swimming speed. The comparisons were conducted at four postcopulatory time points (0.25, 1.5, 3, and 6 hours) in order to detect differences as a function of residence time within the uterus. No significant differences (P less than 0.05) in the parameters were seen between the two types of uterine environments. Residence time within the reproductive tract had no significant effect on the parameters with the exception of percent motile, which was significantly increased (P less than 0.01) at the 1.5-hour postcopulatory time point.
本研究比较了从自然子宫环境(即完整发情期雌性大鼠)中采集的精液样本与从人工诱导子宫环境(即切除卵巢并用激素处理的雌性大鼠)中采集的精液样本的几种大鼠精子参数。所测量的精子参数包括活动百分比、呈前向进行性运动的百分比、实际游动速度和直线游动速度。为了检测子宫内停留时间对精子参数的影响,在交配后的四个时间点(0.25、1.5、3和6小时)进行了比较。两种子宫环境下的参数均无显著差异(P小于0.05)。除活动百分比在交配后1.5小时显著增加(P小于0.01)外,生殖道内的停留时间对这些参数无显著影响。
