Examination of the external genital organs is an integral part of the routine physical examination of the newborn. Early recognition of micropenis or clitoromegaly is important as they may be the only obvious manifestation of pituitary or hypothalamic hormonal deficiencies at birth. Studies suggest that differences in penile or clitoral anthropometry may exist between different populations. Therefore, reference values for genital organs dimensions should be available and well known to medical personnel. We aim to establish reference values for the penile length in Egyptian newborn boys and reference values for the clitoral length in Egyptian newborn girls and to define micropenis and clitoromegaly according to Egyptian reference values.

健康足月埃及新生儿阴茎和阴蒂长度参考值

外生殖器检查是新生儿常规体格检查的一个组成部分。早期识别小阴茎或阴蒂肥大很重要，因为它们可能是出生时垂体或下丘脑激素缺乏的唯一明显表现。研究表明，不同人群之间可能存在阴茎或阴蒂人体测量学的差异。因此，生殖器官尺寸的参考值应该可供医务人员使用和熟知。我们的目标是建立埃及新生男孩阴茎长度的参考值和埃及新生女孩阴蒂长度的参考值，并根据埃及参考值定义小阴茎和阴蒂肥大。
