The prevalence of some minor abnormalities of the male genitalia was studied in 271 boys born over a period of 2 months. The scrotal insertion on the ventral side of the penis was determined in an objective manner by measuring the ratio of the ventral and dorsal length of the unstretched penis. A scrotal insertion ratio of less than 0.48 defined high insertion of the scrotum which was found in 2.7% of our newborn infants. This anatomical finding has an important clinical significance for the performance of early circumcision. The prevalence of hydrocele in all male newborn infants was 57.9%. Extravaginal (communicating) type was present in 86% of all infants, intravaginal (noncommunicating) in 9.5%, while both types of hydrocele in the same neonate was observed in 4.5%. The relatively high frequency of mobile testes (22%) is of interest. The natural history of this entity is not fully understood and the question of follow-up remains open.
对271名在2个月内出生的男童的男性生殖器一些轻微异常的患病率进行了研究。通过测量未拉伸阴茎腹侧和背侧的长度之比，以客观方式确定阴囊在阴茎腹侧的附着情况。阴囊附着比例小于0.48被定义为阴囊高位附着，在我们的新生儿中占2.7%。这一解剖学发现对早期包皮环切术的实施具有重要的临床意义。所有男性新生儿鞘膜积液的患病率为57.9%。所有婴儿中86%为鞘膜外（交通性）类型，9.5%为鞘膜内（非交通性）类型，4.5%的新生儿同时存在两种类型的鞘膜积液。可移动睾丸的相对高发生率（22%）值得关注。该实体的自然病史尚未完全了解，随访问题仍未解决。
