During coitus the penis became erect, etc.
Schrell describes a case in which, independent of the true penis and testicles, which were well formed, there existed a small vulva furnished with labia and nymphae, communicating with a rudimentary uterus provided with round ligaments and imperfectly developed ovaries.
Schrell remarks that in this case we must notice that the female genitalia were imperfectly developed, and adds that perfect hermaphroditism is a physical impossibility without great alterations of the natural connections of the bones and other parts of the pelvis.
Cooper describes a woman with an enormous development of the clitoris, an imperforate uterus, and absence of vagina; at first sight of the parts they appeared to be those of a man.
In 1859 Hugier succeeded in restoring a vagina to a young girl of twenty who had an hypertrophied clitoris and no signs of a vagina.

The accompanying illustrations show the conformation of the parts before operation with all the appearance of ill-developed male genitalia, and the appearance afterward with restitution of the vaginal opening.
Virchow in 1872, Boddaert in 1875, and Marchand in 1883 report cases of duplication of the genitalia, and call their cases true hermaphrodites from an anatomic standpoint.

There is a specimen in St.Bartholomew's Hospital in London from a man of forty-four, who died of cerebral hemorrhage.

He was well formed and had a beard and a full-sized penis.
He was married, and it was stated that his wife had two children.

The bladder and the internal organs of generation were those of a man in whom neither testis had descended into the scrotum, and in whom the uterus masculinus and vagina were developed to an unusual degree.
