Dr. Van Buren is the author of a paper which appeared in the _New York Med. Journal_, November, 1868, in which he attempts to establish the cause as a spasmodic condition of the urethra, forcing the seminal fluid, by reflux action, into the bladder. I can not, at present, think that this is always the case. Only a little attention to physiology will familiarize any person with the calibre-contractions that follow a column of urine from the bladder to the meatus. This same muscular contraction exists in the veins, and is what constitutes the venous wave. The same wave exists in the ejaculation of semen; and where the muscles that perform accelerating movements are paralyzed, the natural consequence must be, that the fluid will remain in its reservoir until its place is supplied by new, and a portion is forced out along the urethra, which drips away when the penis returns to flaccidity. Then, I can but regard this condition, often, as one of paralysis, in which are affected the muscles of ejaculation and acceleration. This condition often exists where the genitals are not impaired as to potence. That such a condition is present, should not be declared until after bougies have proven, to entire satisfaction, the absence of organic stricture or spasmodic contraction. When such a lesion has come on gradually and is of long standing, the prognosis is very unfavorable; as relapses will most generally occur with the slightest indulgence. But when the condition has made its advent suddenly, from inflammatory causes, the prognosis is very favorable. A gonorrhœal orchitis will often produce this condition, which is only transitory, or of a few months’ duration. This is only symptomatic, and very much unlike the true aspermatism of a neurotic origin. A very extraordinary case has of late engaged my attention and curiosity. No case of the kind have I been able to discover, in medical literature or in the practice of my medical friends. _Case._――A young married man consulted me with an affliction (as it were), much to the discomfort of himself and to the great injury of his wife. He never had passed the sexual orgasm, nor ejaculated semen during coition. He is very erotic, and has no difficulty in performing the marital act, but it is followed without the slightest satisfaction. He continues in the act of coition until exhausted, and retires with the wife very much in the same condition after repeated sexual orgasms. He informs me that one hour is not an uncommon length of time for him to occupy in the act of coition, participating in the sexual beatitude during the entire period, until gradually becoming exhausted, when the pleasure dwindles away, but his penis remains erect for some time after. He says that he has often applied cold water to facilitate flaccidity.
