**2.6 Cryptorchidism**

Crptorchidism is a serious developmental disorder while in either one or both the testes fail to descend into the scrotum from abdomen [19]. It is the most common defect of the male reproductive tract pooled in the scientific literature. Almost

3% of full term and 30% of premature infant boys have been reported to born with at least one undescended testis. Absent testis from usual scrotal position can be present anywhere along the path of the descent, in the inguinal canal, ectopic, hypo plastic or dysgenetic.
