I expect that the survival rate should be incredibly close to 100%, if one goes to a surgeon rather than cutting himself. The number of years of life one should expect to lose from dying during an orchiectomy times the probability of death occurring then is going to be hundreds of times less then the expected number of years even a 30-year old would gain from castration.
The survival rate is close to 100% now. However the data that you rely on comes from previous centuries when the survival rate was low. Thus your data set has a literal survival bias.
