The aim of this study was to analyze the recorded annual birth prevalence of isolated undescended testis (IUT<\/jats:styled-content>) in the population\u2010based large dataset of the H<\/jats:styled-content>ungarian Congenital Abnormality Registry for the period between 1962 and 2011, i.e. during the last 50 years. Cases with IUT<\/jats:styled-content> reported after births were evaluated, and their annual rate per 1000 live\u2010births was calculated. The rates of cases with IUT<\/jats:styled-content> were compared with the so\u2010called true rate of IUT<\/jats:styled-content> measured in a previous clinical\u2010epidemiological study based on the personal examination of 10\u2009203 newborn infants. The birth prevalence of cases with recorded IUT<\/jats:styled-content> in H<\/jats:styled-content>ungary was lower than expected based on the true rate of IUT<\/jats:styled-content>. Thus the two waves in the rate of IUT<\/jats:styled-content> were connected with the different completeness of reporting. In conclusion the birth prevalence of cases with IUT<\/jats:styled-content> in H<\/jats:styled-content>ungary did not indicate a real increasing trend during the last 50 years.<\/jats:p>","DOI":"10.1111\/cga.12106","type":"journal-article","created":{"date-parts":[[2015,2,4]],"date-time":"2015-02-04T06:29:33Z","timestamp":1423031373000},"page":"145-149","source":"Crossref","is-referenced-by-count":4,"title":["No increases in the rate of undescended testis in H<\/scp>ungary during the last 50 years: A population\u2010based study"],"prefix":"10.1111","volume":"55","author":[{"given":"Stelios","family":"Mavrogenis","sequence":"first","affiliation":[{"name":"Department of Uro\u2010oncology National Institute of Oncology Budapest Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N\u00e1ndor","family":"\u00c1cs","sequence":"additional","affiliation":[{"name":"Second Department of Obstetrics and Gynecology School of Medicine Semmelweis University Budapest Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew E.","family":"Czeizel","sequence":"additional","affiliation":[{"name":"Foundation for the Community Control of Hereditary Diseases Budapest Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,7,26]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.2910590108"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.92.1.44"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(04)15998-9"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.305.6854.609"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(84)92697-7"},{"key":"e_1_2_5_7_1","first-page":"1462","article-title":"Increasing trends in congenital malformations of male external organs","volume":"1","author":"Czeizel AE","year":"1985","journal-title":"Lancet"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02343229"},{"key":"e_1_2_5_9_1","doi-asserted-by":"crossref","unstructured":"CzeizelAE.1993.Epidemiological studies of congenital abnormalities in Hungary.
