精子的前向运动主要利用三磷酸腺苷(ATP)当精子移动至附睾运动减慢时ATP含量下降,这一过程是精子在附睾中成熟的重要部份。α-糖甙酶由附睾上皮分泌,并被认为是附睾功能良好和开放的一种标志,附睾远端上皮细胞的脱落又称脱离的纤毛束(DCTs)过去曾在一些不育病人中报告过,同时也认为这些DCTs可能来自附睾。故对有DCTs病人和对照组之间比较精子ATP含量和精液中α-糖甙酶的活性来评价附睾功 The forward movement of sperm mainly utilizes adenosine triphosphate (ATP). When the sperm moves to the epididymis, the ATP content decreases when the exercise is slowed down. This process is an important part of sperm maturation in the epididymis. Alpha-glucosidase is secreted by the epididymis epithelium and is considered a hallmark of the well-functioning and open-ended epididymis. The shedding of the distal epididymal epithelium, also known as detached ciliated bundles (DCTs), has been reported in some infertile patients in the past , But also think that these DCTs may come from the epididymis. Therefore, patients with DCTs and control groups compared sperm ATP content and semen α-glycosidase activity to evaluate epididymal function
