Background: Experimental cryptorchidism is a common model for examining the expression and function of heat-induced spermatogenesis related genes in testis. In this study the expression of genes & proteins thatinvolved in programmed cell death after treatment of cryptorchidism was examined.

Over the last 40-50 years studies involving thousands of testicular biopsies in boys with cryptorchidism have contributed to our knowledge of testicular histopathology and our understanding of the effects of cryptorchidism on the normal development of the germinal epithelium. Growth and maturation of germ cells and Leydig cells are crucial to allow boys to reach normal fertility potential. The ...

We report a case of a 2-year-old boy who presented with an empty left scrotum. Clinical examination revealed a left palpable undescended testis. During orchidopexy, segmental atresia of the vas deferens was found, and microsurgical repair was carried out. Segmental vasal atresia is an extremely rare condition and is infrequently diagnosed, especially in the pediatric age group. This is the firs...

The diagnosis of traumatic testicular dislocation was confirmed by ultrasound (fig 2). Closed reduction was unsuccessful and explor...

Objective To evaluate semen quality in infertile men with a history of unilateral cryptorchidism Methods Semen samples were obtained from 47 infertile men with a history of unilateral cryptorchidism. Semen analysis and membrane integrity including both eosin Y stain and hyo-osmotic swelling tests were performed using standard procedures. All men were divided into three groups according to their...
