包皮是男性阴茎外面的一层皮肤。做父母的如果仔细观察会发现,男婴小“鸡鸡”的包皮和阴茎头(又称龟头)会稍有粘连现象,到1岁左右这种粘连逐渐消失,包皮和龟头自然分开。这是正常的生理现象,但如果到了孩童时代龟头还被包皮紧紧地包裹,或者到了青春期龟头仍然“藏而不露”,那就得引起注意了。医学上称这种现象为包茎或包皮过长,是先天性发育异常,并可能隐伏着一些疾患。 Foreskin is a layer of skin outside the male penis. A careful observation of parents will find that the baby boy “chicken” foreskin and penis head (also known as glans) will be a little sticky phenomenon, to 1 year old this adhesion gradually disappear, the foreskin and glans naturally separated. This is a normal physiological phenomenon, but if the glans is still wrapped tightly by the foreskin in childhood or if the glans are still “hidden” in adolescence, then it should be noted. Medically called the phenomenon of phimosis or foreskin is too long, is congenital dysplasia, and may conceal a number of diseases.
