Chromosomal anomalies in cryptorchidism.
Chromosome analysis was performed in 160 patients with cryptorchidism. Chromosomal anomalies were found in 7 patients (4.4%). The incidence of chromosomal abnormalities was not significantly different between patients with bilateral or unilateral cryptorchidism. Of 7 patients, 1 had sex chromosomal aberration, 2 had marker chromosome and 4 had autosomal anomalies. Additional congenital anomalies were observed in 1 with sex chromosomal aberration, 2 with marker chromosome and 2 with autosomal anomaly. These facts indicate that we had better perform chromosome analysis in all patients with bilateral or unilateral cryptorchidism.
