Risk of testicular cancer with cryptorchidism and with testicular biopsy: cohort study.
Swerdlow et al studied a cohort of 1075 men who had been treated for cryptorchidism. In 120 testes that had been biopsied at the time of orchiopexy the relative risk of subsequent development of testicular cancer was 66.7. The corresponding relative risk in 1285 undescended testes that had also been operated on but not biopsied was 6.7. The estimate for testes that were not biopsied is about as...

The genitoinguinal ligament, or gubernaculum, first enlarges to hold the testis near the groin, and then it develops lim...
