ABSTRACT
OBJECTIVE: To determine clitoral size of Korean newborn and androgen hormone levels in clitomegalic newborn. METHODS: The clitoral sizes of 236 Korean female newborn and mother were measured from January in 2000 to March in 2001. Androgen hormone levels were obtained in 11 infants with clitomegaly in order to evaluate the relationship between clitoral hypertrophy and androgen levels. RESULTS: The mean clitoral size of the 236 newborn was 3.82+/-1.47 mm in length and 2.95+/-1.79 mm in width. The mean clitoral size of the 236 postpartum women was 15.8+/-1.03 mm in length and 3.27+/-1.12 mm in width. In the premature infants the clitoral length and width were 4.45+/-1.79 mm and 3.53+/-1.51 mm respectively. In the normal birth weight infants they were 3.70+/-0.75 mm and 2.02+/-0.84 mm respectively. In clitomegalic infants the clitoral size was 5.8+/-0.7 mm in length and 3.7+/-0.4 mm in width. The serum testosterone level was 1.620+/-0.015 nmol/L and dihydrotestoteronesulfate (DHEAS) level 8.44+/-0.01 nmol/L. CONCLUSION: There was no significant correlation between gestational age and clitoral size, but significant negative correlation was found between birth weight and clitoral size. In 11 clito-magalic infants serum androgen was normal level. Also, there was no different clitoral size between clitomagalic infant mothers and normal infant mothers. These RESULTS: suggest that there would be no significant correlation between infantile clitomegaly and androgen level.
