Urologic diseases affected by testosterone can be associated with smaller penis size compared to the normal population. We sought to compare penile length in children with unilateral cryptorchidism and normative data from a cohort of healthy Korean boys.
This study was performed in 259 Korean boys (212, normal cohort; 47, cryptorchidism) aged 6-24 months, each of whom had been brought to an outpatient clinic at one of five tertiary hospitals (Gyeongsangnam-do Province) between April 2014 and June 2015. Penile length was measured via stretched penile length (SPL) and testicular size was measured using orchidometry (mL).
SPL in children with cryptorchidism was significantly shorter compared to a cohort of healthy Korean boys aged 6-24 months (3.7±0.5 cm and 4.3±0.8 cm, p<0.001), although there were no differences with regard to height, body weight and contralateral testicular size between the two groups. According to the stratified ages (6-12, 12-18, and 18-24 months), SPL in children with cryptorchidism was persistently shorter at their ages than those without.
It might be that the penile length aged 6-24 months of children with unilateral cryptorchidism is shorter than that of a cohort of healthy Korean boys.
与正常人群相比，受睾酮影响的泌尿科疾病可能与阴茎尺寸较小有关。我们旨在比较单侧隐睾症儿童的阴茎长度与一组健康韩国男孩的对照数据。
本研究纳入了 259 名 6-24 个月大的韩国男孩（212 名，正常组；47 名，隐睾症组），他们均于 2014 年 4 月至 2015 年 6 月期间在五家三级医院之一（庆尚南道）的门诊就诊。通过伸展阴茎长度（SPL）测量阴茎长度，通过睾丸测量仪（mL）测量睾丸大小。
与 6-24 个月大的健康韩国男孩队列相比，隐睾症儿童的 SPL 明显更短（3.7±0.5cm 和 4.3±0.8cm，p<0.001），尽管两组之间的身高、体重和对侧睾丸大小无差异。根据分层年龄（6-12 个月、12-18 个月和 18-24 个月），隐睾症儿童的 SPL 在其各个年龄段均比无隐睾症儿童的 SPL 更短。
单侧隐睾症儿童 6-24 个月大时的阴茎长度可能短于健康韩国男孩队列。
