On each of these sites there can be an obstacle to passage of a seed liquid of the congenital or got character. Congenital developmental anomalies мочеиспускательного the channel – defect of its back wall (гипоспадия) – lead to that thrown up from incorrectly located external aperture of an urethra of sperm does not get to a vagina, and streams before it. Developed as a result of chronic inflammatory process or damage мочеиспускательного the channel narrowing (стриктура) it also can, though and is very rare, to serve as the barreness reason: thus the seed liquid is late in the channel, is thrown in a bladder or gradually follows upon termination of the sexual intercourse. Most often экскреторной forms of man's barreness serve as the reason of anomaly and diseases of appendages яичек. Bilateral anomalies of appendages яичка in a kind гипоглазии (reduction of the sizes), аплазии (congenital absence) or obliterations (absence of a gleam in this body) meet seldom. Much more often bilateral inflammatory diseases of appendages яичка (эпидидимит) appear the barreness reason. After specific (гонорейного, tubercular) эпидидимита very often there are cicatricial changes which can sharply break movement сперматозоидов on an appendage gleam, up to its full impassability.
