Normal descent occurs in two steps, with the transabdominal phase controlled by a new testicular hormone, insulin\u2010like hormone 3, and the inguinoscrotal phase controlled by androgens. The latter phase requires a complex process of migration from the inguinal abdominal wall to the scrotum and is commonly defective, leading to the high incidence (2\u20134%) of UDT at birth. The clinical examination of babies and infants aims to confirm the persistence of congenital UDT by 3\u20136 months, so surgery can be optimally timed at 6\u201312 months. For those boys who develop acquired UDT later in childhood, the \u2018ascending\u2019 testis often needs surgery between 5 years and 10 years, so all boys should be screened again for UDT at school entry.<\/jats:p>","DOI":"10.1111\/jpc.13744","type":"journal-article","created":{"date-parts":[[2017,11,17]],"date-time":"2017-11-17T03:00:20Z","timestamp":1510887620000},"page":"1101-1104","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Undescended testis: What paediatricians need to know"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3922-8366","authenticated-orcid":false,"given":"John M","family":"Hutson","sequence":"first","affiliation":[{"name":"Urology Department Royal Children's Hospital  Melbourne Victoria Australia"},{"name":"F Douglas Stephens Surgical Research Group Murdoch Children's Research Group  Melbourne Victoria Australia"},{"name":"Department of Paediatrics University of Melbourne  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaya","family":"Vikraman","sequence":"additional","affiliation":[{"name":"F Douglas Stephens Surgical Research Group Murdoch Children's Research Group  Melbourne Victoria Australia"},{"name":"Department of Paediatrics University of Melbourne  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruili","family":"Li","sequence":"additional","affiliation":[{"name":"F Douglas Stephens Surgical Research Group Murdoch Children's Research Group  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joergen","family":"Thorup","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery Righospitalet  Copenhagen Denmark"},{"name":"Faculty of Health and Medical Sciences University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,11,16]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-25910-9"},{"key":"e_1_2_13_3_1","first-page":"176","article-title":"Germ cell development in the postnatal testis: The key to prevent malignancy in cryptorchidism?","volume":"3","author":"Hutson JM","year":"2012","journal-title":"Front.
