Effect of cryptorchidism and retractile testes on male factor infertility: a multicenter, retrospective, chart review

Fertil Steril. 2005 May;83(5):1581-4. doi: 10.1016/j.fertnstert.2005.01.088.


This multicenter retrospective chart review study performed on 162 cryptorchid patients and on 34 subjects with retractile testes suggests that cryptorchidism and retractile testes can alter spermatogenesis, with more serious damage observed in bilateral cryptorchidism. This spermatogenetic impairment is probably related to the lack of an appropriate or timely surgical correction.
