[Cryptorchism: long-term results in subjects evaluated in a conjugal infertility service (monolateral cryptorchism fertility)].

Infertile male subjects because of cryptorchidism have an overall rate of 0.5-1%. Undescended testis even if treated by surgery and/or hormonal therapy have a bad seminal map. However in Author's experience, the hormonal treatment give a significant improvement in terms of fertility. Biopsies carried out on undescended testis demonstrated an early cellular damage of the testis.
