Cryptorchidism is the most common genitourinary disorder of childhood, resulting in 27,000 surgical cases each year in the United States. Of the 3% of full-term infants affected, most will have testes that will descend normally within a few months. The remaining 1%, who have a cryptorchid condition that persists, should consider medical or surgical intervention. In addition, although the effect of cryptorchidism on testicular development and fertility has been studied extensively, the only fact of certainty is that untreated men with bilateral abdominal testes will be infertile. The remaining scenarios (unilateral, inguinal, gliding, and medically or surgically treated conditions) offer unpredictable levels of fertility. Fortunately, based on recent research, the correlation between testis maldescent and infertility may not be as prevalent as previously reported.
隐睾症是儿童期最常见的泌尿生殖系统疾病，在美国每年有27000例手术病例。在受影响的3%的足月儿中，大多数婴儿的睾丸会在几个月内正常下降。其余1%患有持续性隐睾症的婴儿，应考虑医学或手术干预。此外，尽管隐睾症对睾丸发育和生育能力的影响已得到广泛研究，但唯一确定的事实是，双侧腹内睾丸未经治疗的男性将无法生育。其余情况（单侧、腹股沟、滑动性以及经医学或手术治疗的情况）的生育能力难以预测。幸运的是，根据最近的研究，睾丸下降异常与不育之间的关联可能并不像先前报道的那么普遍。
