To the Editor:—  The author of the answer to the question on undescended testes in The Journal, June 11, page 742 states, "... since only 12% of testicular tumors occur in undescended testes, surgical exploration can be delayed until such time as more definite indications exist."This I cannot understand. I do not know the incidence of undescended testes, but I would guess it is but a fraction of 1%. If tumor development in testes had nothing to do with testicular ectopy, then the incidence of ectopy should be the same in testes, tumorous and non-tumorous, i. e., the incidence of ectopy in testes with tumors should also be only a fraction of 1%. It is much higher in tumor-bearing testes, suggesting a causal connection between ectopy and malignant changes. Thus, the statistical information in the expert's answer is a strong argument for removal of undescended testes, not against it.To
