精囊是男性附属性器官之一,它的分泌物含有果糖,柠檬酸以及多种酶,参与精液的组成,因此对男性生殖和精子的活动超重要作用。精囊的形态结构和功能直接依赖于雄激素的作用。性激素和促性腺激素以及抗促性腺激素等均能引起精囊(主要是精囊上皮)形态结构以及分泌活动发生极其明显的改变从而影响生殖功能。通过改变附属性器官的分泌功能,我们有可能达到男性节育的目 Seminal vesicle is one of the male accessory organs, its secretion contains fructose, citric acid and many enzymes involved in the composition of the semen, so the male reproductive and sperm activity is super-important role. The structure and function of the seminal vesicle directly depends on the role of androgens. Sex hormones and gonadotropins as well as anti-gonadotropin and other can cause the seminal vesicle (mainly seminal vesicle) morphological structure and secretion of very significant changes in the impact of reproductive function. By changing the secretion of accessory organs, we are likely to reach the goal of male birth control
