Convulsive spermatorrhœa is not very common, while a person is awake: it then rarely presents the purely convulsive character, with perfect erection, and distinct ejaculation, that is seen in a healthy emission of semen. This state, however, is possible: an instance of it may be seen in the case of satyriasis stated by M. Duprest-Rony. Whenever this young man beheld his mistress looking at him, erection took place, and ejaculation followed. He, however, had refrained from masturbating for two years, and had regained in a great measure his former strength. M. Sainte Marie has reported a case of priapism, during which the patient ejaculated fourteen times in a few hours. But this affection was not in consequence of venereal excesses, and the emission of semen presented nothing more extraordinary than other cases of priapism. Diurnal convulsive pollution is seldom accompanied, in individuals exhausted by abuses of masturbation and coition, with a perfect erection. The size of the penis increases, but it does not become hard. The semen is then emitted only to a short distance, if there be any ejaculation. The least cause, the slightest touch, is sufficient to excite this. Thus, in a man thirty years old, whom Tissot has mentioned, after Boerhaave, the semen escaped whenever there was a commencement of an erection, for it was never complete; and instead of being expelled forcibly, it oozed out drop by drop. The patient became impotent. This symptom (adds Tissot) is very frequent among those who are exhausted, and it contributes to continue the exhaustion. The slightest excitement causes the commencement of an erection, which is followed by an emission. We have seen a similar phenomenon in one of the patients of M. Dalandeterie. There were frequent painful erections, of short duration, which always terminated by a more or less abundant discharge of fluid. These kinds of pollutions were always painful, and were followed by extreme prostration. It is evident, from the remarks we have quoted, that there was no ejaculation in this patient; and probably, also, the erections, though painful, were imperfect. Daily convulsive spermatorrhœa assumes then, as it were, a bastard character in onanists: it occupies an intermediate place between proper convulsive spermatorrhœa, such as occurs during sleep, and the non-convulsive spermatorrhœa, which we shall mention directly.
