Chromosomal studies in cryptorchidism.
The chromosomes of undescended tests from 13 boys were analyzed. In 12 of these patients the peripheral blood chromosomes were examined and in 7 the chromosomes of normal skin cultures were examined. In addition to standard techniques the chromosomes also were analyzed by G and Q-banding methods. We were unable to detect any significant abnormalities of either chromosome number of structure in the undescended testes. Thus, our investigation failed to demonstrate a chromosomal lesions that may be responsible for maldescent of the testes. Our investigation did not reveal any changes in the chromosomes of these undescended testes that could be interpreted as indicating a potentially malignant state.
