Castration is of no use nowadays when medical science and technology are so advanced.
Do you know about Pen*le grafts using the thigh muscle flap technique?We can literally make a new and Improved Pen*s for the ones who had accidental castration, hell many women undergo sex change operation that Urologists will implant new organs on them and they are dime a dozen in pron industry.
As for ED =Erectile Dysfunction sufferers we have Pen*ile prosthetic implants.Even a 90 year old with these prosthesis can have s*x anytime any time he wants nowadays and the results and sensation are the same as normal natural one, not to mention the variety of Erection drugs in market, soon there will be gene therapy to completely rid of ED in males already there is lot of work done and some are in test trials it will be out in some 5-10 years.
There are two primary types of penile prosthesis: noninflatable, semirigid devices and inflatable devices.
[6] Noninflatable, semirigid devices consist of rods implanted into the erection chambers of the penis and can be bent into position as needed for sexual penetration. With this type of implant the penis is always semi-rigid and therefore may be difficult to conceal.
Penile prosthesis - Wikipedia, the free encyclopedia
Hydraulic, inflatable prosthesis also exist and were first described in 1973 by Brantley Scott et al.
[7] These saline-filled devices consist of inflatable cylinders placed in the erection chambers of the penis, a pump placed in the scrotum for patient-activated inflation/deflation, and a reservoir placed in the abdomen which stores the fluid. The device is inflated by squeezing the pump several times to transfer fluid from the reservoir to the chambers in the penis. After successful sexual relations, the pump can be deactivated to return the penis to a flaccid condition. Almost all implanted penile prosthesis devices perform satisfactorily for a decade or more before needing replacement
So i don't know how any castration works if the person is in touch with latest medical developments he will pay money to a urologist and claim he was accidentally castrated and the UroSurgeon will make him a new appendage any time.
