Testicular Cancer and Cryptorchidism [PDF]
Frontiers in Endocrinology, 2013 The failure of testicular descent or cryptorchidism is the most common defect in newborn boys. The descent of the testes during development is controlled by insulin-like 3 peptide and steroid hormones produced in testicular Leydig cells, as well as by various genetic and developmental factors.

Cryptorchidism and Fertility [PDF]
Clinical Medicine Insights: Reproductive Health, 2015 Cryptorchidism, the failure of one or both testes to descend into the scrotum prenatally, occurs in 2.4%-5% of newborns. Many of these testes will descend spontaneously shortly after birth, but ~23% will remain undescended unless surgery is performed.

Spermatogenesis and Cryptorchidism [PDF]
Frontiers in Endocrinology, 2014 Cryptorchidism represents the most common endocrine disease in boys, with infertility more frequently observed in bilateral forms. It is also known that undescended testes, if untreated, lead to an increased risk of testicular tumors, usually seminomas, arising from mutant germ cells.

Genomic copy number variation association study in Caucasian patients with nonsyndromic cryptorchidism [PDF]
, 2016 Copy number variation (CNV) is a potential contributing factor to many genetic diseases. Here we investigated the potential association of CNV with nonsyndromic cryptorchidism, the most common male congenital genitourinary defect, in a Caucasian ...

Investigation of the Protective Effects of Amlodipine on the Structure and Function of Testicular Tissue following Experimental Unilateral Cryptorchidism in Rats [PDF]
Iranian Journal of Veterinary Surgery, 2019 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 ...
