Nine male infants who developed scrotal hair with no other signs of virilization were evaluated. Median age for the development of scrotal hair was 4.5 months, and median age at presentation was 7.5 months. Endocrinologic investigations performed in 6 of the infants yielded normal findings. The scrotal hair receded at a mean age of 12 months, suggesting a transient benign event. The development of genital hair in boys under age 9 years is considered precocious, suggesting a possible pathological condition (eg, precocious puberty, congenital adrenal hyperplasia, adrenal or genital tumors), or may be due to premature adrenarche.
对9名出现阴囊毛发但无其他男性化体征的男婴进行了评估。出现阴囊毛发的中位年龄为4.5个月，就诊时的中位年龄为7.5个月。对其中6名婴儿进行的内分泌学检查结果正常。阴囊毛发在平均12个月龄时消退，提示这是一个短暂的良性事件。9岁以下男孩出现生殖器毛发被认为是性早熟，提示可能存在病理状况（如性早熟、先天性肾上腺皮质增生症、肾上腺或生殖器肿瘤），也可能是由于肾上腺功能初现过早。
