精囊的生理功能与男性不育的关系

精囊作为男性生殖系统的重要附属性腺，在男性生殖过程中发挥重要作用。精囊分泌多种物质，如果糖、抗坏血酸、凝集酵素和前列腺素等。前列腺素及多种蛋白质具有多种作用，包括精液凝固、调节精液的黏稠度、维护精子DNA的稳定性以及抗氧化作用等。精囊发育不良与精囊相关疾病如精囊炎、精囊囊肿等，均会造成男性不育症的发生。精囊镜的普及与广泛应用也为精囊相关疾病的诊断及治疗提供了一种新的手段和治疗策略。现就精囊生理功能及其功能障碍引起男性不育的最新进展作一综述。

The Association between Seminal Vesicle and Male Infertility

Seminal vesicles, as an essential affiliated sexual gland, are important for male reproduction. Seminal vesicles can secrete various substances and factors, such as fructose, ascorbic, agglutinin, prostaglandin, etc. Prostaglandin and many proteins are necessary for seminal coagulum, seminal viscosity, the stability of sperm DNA and antioxidative reactions. Seminal vesicle dysplasia and disorders such as seminal vesiculitis, seminal vesicle cysts, etc., will result in male infertility. The seminal vesiculoscopy has been widely used in those diseases related to seminal vesicle, which provides a new strategy for clinical diagnose and treatment.
