Clitoral sizes and anogenital distances in term newborns in Nigeria.

ABSTRACT: Background:Previous studies suggest significant ethnic and racial differences in clitoral sizes and anogenital distances in the newborn. This study aimed to document normative data on clitoral sizes and anogenital distances of apparently normal term female infants in Sagamu. Methods:The study was a multi-center, cross-sectional descriptive research carried out among 317 female term infants within the first 72?h of life. Interviewer-based questionnaire was applied to obtain sociodemographic data, pregnancy and birth history. A sliding digital caliper was used for measurement. Data analysis was with SPSS version 20.0. Results:The mean clitoral length was 6.7?±?1.6?mm while the mean clitoral width was 5.6?±?0.8?mm. The mean fourchette-clitoris distance, anus-clitoris distance and anus-fourchette distance were 21.9?±?2.1?mm, 35.5?±?2.5?mm and 17.0?±?2.6?mm respectively. The anus-clitoris and anus-fourchette distances significantly correlated with the anthropometric parameters while the clitoral measurements did not. Conclusion:The mean values recorded in this study were higher than observed in most previous studies. This simple, affordable and non-invasive evaluation could aid early diagnosis and treatment of female infants with potentially harmful conditions such as congenital adrenal hyperplasia.
