In prostatorrhoea the discharge is never milky, white or purulent as in pure prostatitis. Microscopically the slowly dried slide shows the characteristic crystals of sodium chloride, but no spermatozoa. In prostatorrhoea the orifice of the urethra shows constant moisture. The copious evacuations occur while straining in the water-closet. The patients are, as a rule, constipated. The discharge is attended with peculiar sensations, sometimes of a pleasurable nature, sometimes of a dropping sensation, weight in the region of the prostate, anus and rectum. Examination per rectum often shows hard points and nodules in the prostatic gland. The most frequent anomaly caused by venereal excesses is spermatorrhoea and nocturnal pollutions. The excesses provoke a chronic hypertrophy of the prostatic gland, and this hypertrophy renders the ejaculatory ducts insufficient. In spermatorrhoea there is an oozing of semen from the urethra without erection or pleasurable sensations. The rhythmic muscular contractions, found in normal ejaculations, are missing here. The failure of the normal contractions is due to a paresis of the muscular fibres of the ejaculatory ducts. Spermatorrhoea usually takes place after micturition or during defecation. Sometimes spermatorrhoea is caused by the slightest excitement. The sight of a woman’s bust or of her leg, the touch of her hand, the smell of her perfume, the glance at a lascivious painting, or a voluptuous thought may cause a precipitate discharge, without an erection or with an imperfect erection. The discharge taking place at a complete relaxation of the ejaculatory ducts, the voluptuous sensations are, as a rule, entirely absent. Spermatic discharges sometimes occur in affections of the central nervous system, where the usual inhibitions through consciousness are ineffectual. Microscopically the discharge in spermatorrhoea shows amyloid bodies, lecithin and prostatic epithelia. The fluid has the seminal odor which is peculiar to the spermin reaction; the amount of spermatozoa is somewhat diminished. The testicles and the skin of patients, suffering from spermatorrhoea, are less sensitive to electrical stimulation, while the urethra is hypersensitive.
