background: disruption of testicular function and arrest ofspermatogenesis are the consequence of cryptorchidism inresponse to elevated temperature. objectives:this investigationwas set to clarify the possible ghrelin efficacy in altering somesperm quality parameters upon experimentally-induced cryptorchidism.methods: thirty male adult rats were scheduled for thestudy and were divided into thre...

Objective- Cryptorchidism, common birth defect of the male genital tract, is one of the causes of fertility problems. The elevation of tissue temperature following of cryptorchidism could induce oxidative stress which influences the cellular and tissue degeneration. Amlodipine is a third-generation of calcium channel blockers which has antioxidant activity. The aim of this stud...

UNLABELLED We investigated whether or not surgical strategy has an impact on the risk of invasive testicular neoplasia in cases of cryptorchidism. We made a database study of the incidence of testicular neoplasia at surgery for cryptorchidism in childhood, and evaluated if such abnormalities were found in special categories of patients, and also of the incidence of testicular neoplasia after or...

Background and objectives: Cryptorchidism or undescended testicle, with a prevalence of 33 percent in preterm and 3-5 percent in term infants, is the most common congenital abnormality in newborn boys. The present study aimed to assess the recovery rate and urinary tract infection among infants with cryptorchidism during the first 15 months of their life.         Methods: This cross-sectional d...

Cryptorchidism is a well-known congenital anomaly in children. However, its diagnosis is often delayed for reasons including patient unawareness or denial of abnormal findings in the testis. Moreover, it has been difficult to establish an optimal treatment strategy for postpubertal cryptorchidism, given the small number of patients. Unlike cryptorchidism in children, postpubertal cryptorchidism...

Background Cryptorchidism is defined the failure of one testis or both testes to permanently descend. It is considered as the most common congenital abnormalities. The risk of testicular cancer in men with a history of cryptorchidism increased from three fold to four fold, compared to those without history of cryptorchidism. We aimed to investigate prevalence and pathological features of crypto...

BACKGROUND Cryptorchidism, hypospadias, and testicular germ cell cancer (TGCC) may be symptoms of a testicular dysgenesis syndrome that manifests during fetal life. To address the inheritability of this syndrome, we examined whether family history of cryptorchidism or hypospadias is associated with an increased risk of TGCC. METHODS A total of 2,159,883 men born since 1953, identified through...

Cryptorchidism is the most frequent congenital birth defect in male children (2-4% in full-term male births), and it has the potential to impact the health of the human male. In fact, although it is often considered a mild malformation, it represents the best-characterized risk factor for reduced fertility and testicular cancer. Furthermore, some reports have highlighted a significant increase ...

BACKGROUND Cryptorchidism is a frequent syndrome occurring in 1-2% of males within the first year of age. Autoimmune reactions, particularly directed to testicular elements and/or spermatozoa have been found to be often associated with cryptorchidism. Therefore we investigated in this study the frequency of HLA class II alleles in order to recognize possible genetic predisposition for antisperm...
