It requires surgery in childhood, increases the risk of fertility disorders and cancer. As a major public health objective, it's the subject of numerous recommendations. Its frequency is increasing in some countries faster than a single genetic cause could not explain it. It may occurs in a geographic cluster. The cause of cryptorchidism involves genetic, hormonal and environmental factors. Animal studies suggest that endocrine disruptors interfere with fetal testicular migration. The aim of the study is to find out if some environmental exposition may be associated with cryptorchidism.","Parent of patient with cryptorchidism",[33,37],{"label":31,"type":26,"description":34,"interventionNames":35},"parent exposition of endocrine disruptors",[36],"Other: Measure of the exposure of parent of male with \u002Fwithout cryptorchidism to endocrine disruptors",{"label":38,"type":26,"description":39,"interventionNames":40},"Parent of patient without cryptorchidism","Parent exposition of endocrine disruptors",[36],[42],{"type":6,"name":43,"description":44,"armGroupLabels":45,"otherNames":26},"Measure of the exposure of parent of male with \u002Fwithout cryptorchidism to endocrine disruptors","Measure of the exposure of parent of patient with\u002Fwithout cryptorchidism to endocrine disruptors (job exposure, during pregnancy)",[31,38],[47],{"name":48,"role":49,"phone":50,"phoneExt":26,"email":51},"Nicolas KALFA, MD","CONTACT","00334 67 33 87 84","n-kalfa@chu-montpellier.fr",[53],{"facility":54,"status":55,"city":56,"state":26,"zip":57,"country":58,"countryCode":59,"cosmosGeoPoint":60,"geoPoint":65,"contacts":66},"University hospital of Montpellier","RECRUITING","Montpellier","34295","France","FR",{"type":61,"coordinates":62},"Point",[63,64],3.87635,43.61093,{"lat":64,"lon":63},[67,70],{"name":68,"role":49,"phone":69,"phoneExt":26,"email":51},"nicolas KALFA, MD","334 67 33 87 84",{"name":71,"role":72,"phone":26,"phoneExt":26,"email":26},"nicolas kalfa, MD","PRINCIPAL_INVESTIGATOR",{"type":74,"investigatorFullName":26,"investigatorTitle":26,"investigatorAffiliation":26,"oldNameTitle":26,"oldOrganization":26},"SPONSOR",[76],{"name":77,"class":6},"University Hospital, Bordeaux","100388759",false,"NCT04342026","Role of the Environment and Endocrine Disruptors in Child Cryptorchidism","CRYPTENV","Inclusion criteria:\n\n\\- Parents of male children from the neonatal period to 18 years of age (during surgery) with cryptorchidism\n\nExclusion criteria:\n\n* Parents of children without endocrine disease.
