Abstract

In a study of the incidence of hypospadias the source material consisted of cases of hypospadias continuously reported to two central registers during the years 1965 to 1968. The material was then extended by the addition of hypospadiacs aged 5 to 9 years and admitted to departments of plastic and pediatric surgery, and in a few cases to departments of urology or surgery, who were not reported to either of the registers. During the years 1965 to 1968, 666 live male infants with hypospadias were identified among a total of 480 607 live births of both sexes in Sweden. The incidence of hypospadias was 13.9 per 10000 of both sexes. 13.1 of these were single and 0.8 multiple malformations. A systematic grading of hypospadias showed that the mildest, glandular form was present in 62%. Early neonatal deaths with identified hypospadias was 7.
