Interesting as are all the anomalies of conception, none are more so than those of unconscious impregnation; and some well-authenticated cases can be mentioned. Instances of violation in sleep, with subsequent pregnancy as a result, have been reported in the last century by Valentini, Genselius, and Schurig. Reports by modern authorities seem to be quite scarce, though there are several cases on record of rape during anesthesia, followed by impregnation. Capuron relates a curious instance of a woman who was raped during lethargy, and who subsequently became pregnant, though her condition was not ascertained until the fourth month, the peculiar abdominal sensation exciting suspicion of the true nature of the case, which had previously been thought impossible. There is a record of a case of a young girl of great moral purity who became pregnant without the slightest knowledge of the source; although, it might be remarked, such cases must be taken "cum grano salis." Cases of conception without the slightest sexual desire or pleasure, either from fright, as in rape, or naturally deficient constitution, have been recorded; as well as conception during intoxication and in a hypnotic trance, which latter has recently assumed a much mooted legal aspect. As far back as 1680, Duverney speaks of conception without the slightest sense of desire or pleasure on the part of the female. Conception with Deficient Organs.--Having spoken of conception with some obstructive interference, conception with some natural or acquired deficiency of the functional, organic, or genital apparatus must be considered. It is a well-known fact that women exhibiting rudimentary development of the uterus or vagina are still liable to become pregnant, and many such cases have been recorded; but the most peculiar cases are those in which pregnancy has appeared after removal of some of the sexual apparatus.
