人的正常精液呈乳白色,有一股特殊的腥味。如果排出的精液呈棕红、红褐色或混有血丝,称为血精症。此时取一滴精液放在显微镜下观察,可见其中含有大量的血细胞。血精症大多发生在性生活旺盛的中青年身上。其原因既有生理性的,也有病理性的,如出血,炎症甚至肿瘤等引起。 偶然发生血精,大多是属于生理性的.由于射精时精囊发生剧烈地收缩,使内部压力骤增,而射精结束精囊又变为松弛,内部压力迅速下降。这种大起大落的变化,容易引起精囊管壁毛细血管的通透性改变,使血管中的红细胞渗透到精液中,以致下次射出的精液中含有红细胞。若性交过程中某些组织因急剧充血和机械碰撞出现微细小血管破裂,也可导致血 Normal human semen was milky white, there is a special smell. If the discharge of semen was brown, reddish brown or mixed with bloodshot eyes, known as blood sperm disease. At this point take a drop of semen on the microscope, we can see that which contains a large number of blood cells. Most seminogens occur in young and middle-aged sexually active persons. The reason for both physiological, but also pathological, such as bleeding, inflammation and even caused by tumors. Occasional blood serum, most of them are physiological.Because the ejaculation severe contraction of the seminal vesicle, so that the internal pressure surge, while the ejaculation seminal vesicle has become loose, the rapid decline in internal pressure. This ups and downs of the change, easily lead to changes in the permeability of the capillaries of the seminal vesicles, so that blood cells in the red blood cells penetrate into the semen, so the next injection of semen contains red blood cells. If sexual intercourse in some organizations due to rapid hyperemia and mechanical collision of micro-small blood vessels rupture can also lead to blood
