Cytogenetic analysis of men with cryptorchidism and reduced fertility.
A cytogenetic chromosomal analysis was performed in 140 infertile men with cryptorchidism--85 with unilateral and 55 with bilateral. The most frequent anomaly was sex chromosomal aneuploidy found in 7.1% of patients. This is significantly higher compared to a group of infertile men with normal descended testes. Other chromosomal anomalies were not more frequent than in infertile men without cryptorchidism.
