On examination by the surgeons she was found to have a dense membrane, of a fibrous nature, entirely occluding the vagina, which they incised.

Immediately afterward the woman exhibited morning sickness and the usual signs of pregnancy, and was delivered in four months of a full-term child, the results of an impregnation occasioned by one of the unsuccessful attempts at entrance.

Such instances are numerous in the older literature, and a mere citation of a few is considered sufficient here.

Zacchias, Amand, Fabricius Hildanus, Graaf, the discoverer of the follicles that bear his name, Borellus, Blegny, Blanchard, Diemerbroeck, Duddell, Mauriceau, a Reyes, Riolan, Harvey, the discoverer of the circulation of the blood, Wolfius, Walther, Rongier, Ruysch, Forestus, Ephemerides, and Schurig all mention cases of conception with intact hymen, and in which there was no entrance of the penis.

Tolberg has an example of hymen integrum after the birth of a fetus five months old, and there is recorded a case of tubal pregnancy in which the hymen was intact.
Gilbert gives an account of a case of pregnancy in an unmarried woman, who successfully resisted an attempt at criminal connection and yet became impregnated and gave birth to a perfectly formed female child.
The hymen was not ruptured, and the impregnation could not have preceded the birth more than thirty-six weeks.
