Inflammation of the urethra may become very intense, and extend to the bladder, particularly when venereal excesses coexist with intemperate habits: the discharge of urine may then be interrupted, and consequently all the symptoms of dysuria and strangury may supervene. Chronic catarrh of the bladder is often observed, also, in those individuals who have abused the pleasures of love. Montegre, speaking of a kind of cystitis, which he terms _vesical hemorrhoids_, mentions among its causes venereal excesses, and particularly those repeated titillations, which keep the genital organs in a state of semi-orgasm, which is not terminated by any crisis. Lallemand reports the case of an individual, who, being addicted to venereal excesses, experienced frequent desire to urinate, and found it difficult to empty his bladder. Finally, unable to pass water without the use of a sound, he learned to introduce it himself. This was not difficult, although the bladder could not be emptied without it. The urine was turbid, thick, and deposited a great deal of glairy mucus, which adhered to the pot de chambre. The prostatic portion of the urethra was cauterized, but without success. Lallemand thought that there was a morbid development of the middle lobe of the prostate gland. In another patient, whose history is given by this excellent observer, excessive masturbation appeared to have predisposed to a chronic inflammation of the genito-urinary organs, which were developed under the influence of the abuse of coition. (_Obs._, &c., p. 440.) It is easily seen, that if coition and masturbation may cause all these inflammations, so, too, they may sustain and increase them. The pleasures of love, therefore, should be strictly forbidden to persons affected with diseases of the genito-urinary passages. Acute inflammation of the urethra, blenorrhagia, has often been known to pass to a chronic state by a single act of venery; which, says Lewedrain, may even cause this change several months after the apparent termination of acute blenorrhagia. May an incontinence of urine be produced by excesses in coition or masturbation? We have more than once seen this disease in young onanists. Sainte Marie, also, places it among the symptoms of daily involuntary pollution; and Lallemand has remarked, that most individuals affected with this pollution had been subject, in their infancy, to incontinence of urine. May not the relations between these two affections extend to the causes which determine them? One of the most common causes of excesses in venery is, the _involuntary loss of semen_. This disease, which has been termed _spermatorrhœa_, _involuntary pollution_, may also arise from other causes; but as it results most frequently from excesses in masturbation or coition, we shall devote particular attention to it.
