The incidence of prepucial Epstein pearls was found in 7.3/1000 live born male newborn babies. Gestational age and birth weight were the important determinants as 72.7% babies were term and 54.5% babies weighed 3000 g or more. The formation of Epstein pearl on the prepuce was independent of that of palatal Epstein pearl.
在每1000例存活男婴中，发现包皮埃普斯坦珠的发生率为7.3。胎龄和出生体重是重要的决定因素，72.7%的婴儿为足月儿，54.5%的婴儿体重在3000克或以上。包皮上埃普斯坦珠的形成与腭部埃普斯坦珠的形成无关。
