I think BridgetteFeels asked for what the french speaking world understands with 'Bistournage'.
This castration form results from the torsion of the testicular cords within the scrotum. So this scrotum is not opened !
What is bistournage ?
The scrotum can be regarded as just a sac containing the two testicles hanging on a cord. Simple thinking may lead to a very simple way of castration, especially in those patients with long scrotal necks: Just turn the testicle round its own axle and a torsion of the cord is the result. This torsion obliterates the blood vessels and the testicle dies of hypoxia.
This is/was a castration method in older days. The big advantage was there was no cutting, no wound, so no risk of infection. Disadvantage was the method is not reliable. Why ?
Why is the method not reliable ?
Nature is not stupid. During development human gonads (these gonads develop in ovaries or testicles depending on the chosen sex, XX or XY) are located in the belly. They are conected with a membrane that pulls them down.
Female ovaries will be connected to the this membrane, 'ligamentum rotundum' which holds the ovaries in the neighbourhood of the womb .
Male testicles will locate themselves in the scrotum, pulled downwards by their connected membrane or 'gubernaculum'. (I believe I ones read that at a certain stade this membrane develops muscle tissue to pull the testicles downwards. Failure can lead to cryptorchidism). After the testicular descent it remains as a small but important fibrous connection between the scrotum and the testicle.
This gubernaculum prevents turning of the testicle in its own sac because it is connected to.
However
Active turning and twisting of the testicles can lead to the testicular death and so castration in certain animals. As stated, this method has been described. I have an old french book (1941) in which the method is described along with other approaches: tearing out the testicles with the teeth, torsion until rupture (manual version of the Henderson, I think), elastration, Burdizzo.
The book rejects elastration because of the pain and risk of infection. The book prefers the bistournage (if in good hands because it does not seam to be an easy procedure) and burdizzo method. Open procedures are done in bigger animals.
Human analogue
A similar condition of testicular torsion occur sometimes spontaneously in humans. Especially postpuberal boys and young men can have this problem.
Due to an incomplete or loose gubernaculum the testicle can sometimes turn upon its own. This results in what docs call: acute scrotum: The testicle, not having enough blood and oxygen cries for it: An unusual great pain, without trauma before starts in the groin, irradiates towards the kidney region.
Some boys are afraid to tell this because it usually happens after masturbation (due to contraction of the dartos during this), and actually try to harden this pain. It seems a hot bath can ease the pain. A testicle that is ischaemic for a few hours is most probably lost. It appears that due to immunologic changes it even can deteriorated the fertility of the other (healthy) testicle.
One could find more and even with pictures at google (images). Just look for 'acute scrotum'.
And my attempts:
I often tried to turn my testicles. It does not work. Fortunately ?
However, after twisting the testicle twice, traction on the testicle gives a profound feeling ...
Hoping to have helped some what,
Take care !
Vesal.
Excellent post.
