精液由精浆和精子组成,精子由睾丸生精细胞产生,在附睾内成熟,通过输精管运输。精浆主要是由前列腺、精囊腺、尿道球腺等附属腺体分泌。精浆主要来源于精囊腺和前列腺,前者占60%,后者占30%,其余10%由附睾、输精管壶腹部、尿道球腺等组织所分泌。在这个过程中,任何一个器官、环节等出现异常,都会引起精液的变化。 Semen consists of seminal plasma and sperm, produced by the spermatogenic cells of the testes, matured in the epididymis and transported through the vas deferens. Seminal plasma is mainly by the prostate, seminal vesicles, urinary bulb gland and other subsidiary gland secretion. Seminal plasma is mainly derived from seminal vesicles and prostate, the former accounted for 60%, the latter accounted for 30%, the remaining 10% by the epididymis, ampulla of the ampulla, urethral gland and other organizations secreted. In this process, any one organ, links and other abnormalities, will cause changes in semen.
