精子在睾丸内形成后在功能上并未完全成熟,要经过附睾,受到附睾内各种因素的影响,才逐渐获得运动和授精的能力趋于成熟阶段。干扰精子在附睾中成熟的过程,就可能使精子失去授精和运动的能力从而达到节育的目的,因而研究附睾的生理功能,对男性计划生育科研有重要意义。一、附睾的功能 (一)附睾的分部:根据结构和功能的不同,附睾常分为头、体、尾三部份,这三部份还可分为若干亚段(Subsegment),附睾上皮有其独特的细胞类型和功能特点,组织化学也有明显差异。附睾上皮密切依赖睾丸雄激素以维持其结构及分泌、吸收、生物
After the formation of spermatozoa in the testis is not fully functional in function, to go through the epididymis, by the epididymis of various factors before they gradually gain the ability to exercise and insemination tends to mature stage. Interfere with sperm maturation process in the epididymis, sperm may lose the ability of insemination and exercise to achieve the purpose of birth control, and thus study the physiological function of epididymis, male research in family planning is of great significance. First, the epididymal function (a) epididymal Division: According to the different structures and functions, epididymis is often divided into three parts, the first three parts can be divided into several sub-segments (Subsegment), epididymal epithelium Has its unique cell types and functional characteristics, histochemistry, there are significant differences. Epididymal epithelium closely depends on testicular androgen to maintain its structure and secretion, absorption, biology
