The month of birth of boys undergoing orchidopexy in the Oxfordshire Health District during the years 1974-83 was analysed. A significant seasonal variation with a peak in April was found for those boys operated upon by paediatric surgeons at a young age (0-4). Possible causes of this variation and its relationship to the aetiology of cryptorchidism are discussed.

OBJECTIVE To evaluate the clinical and histopathological results of adult unilateral cryptorchidism patients. MATERIAL AND METHODS Data from adult unilateral cryptorchidism patients that underwent orchiectomy in our clinic between between January 2004 and March 2013 were retrospectively evaluated. Patients were divided into three groups as intra-abdominal, inguinal canal and superficial ingui...

BACKGROUND We conducted genital health wellness screens in male kindergarten children between the ages of 3 and 6 years to assess the incidence of congenital abnormalities and their treatment. METHODS We performed genital examinations on 2241 male children in 8 kindergartens. We screened for 4 conditions: phimosis, hypospadias, cryptorchidism, and hydrocele/hernia. We assessed the incidence o...

BACKGROUND The upward trend in industrial nations in the incidence of male genitourinary (GU) conditions may be attributed to increased exposure to endocrine disruptors. Polybrominated biphenyl (PBB), a brominated flame retardant, is one such suspected endocrine disruptor. OBJECTIVE We investigated the relationship between maternal serum levels of PBBs and GU conditions among male offspring e...

Insulin-like factor 3 (INSL3) plays a crucial role in testicular descent. Genetic ablation of Insl3 or its G protein-coupled receptor, leucine-rich repeat-containing G-protein-coupled receptor (Lgr8), causes cryptorchidism in mice. Mutation analyses of INSL3 in humans showed an association with cryptorchidism but led to non-conclusive data about a causative role. In this study, we explored the ...

This review describes the most recent data on the eff ects of endocrine disrupting compounds on reproductive tract development, as well as controversies in the fi eld. One of the most frequent conditions aff ected by endocrine disrupting compounds is cryptorchidism. Recent reports regarding the cause of this disorder continue to increase our understanding of this common and important problem. E...
