以前作者根据有限数目的睾丸活检,同意了Robinon和Engle二氏意见,认为男性生殖腺在5岁以前为静止阶段。今天又积累了更多的组织学数据,这个看法必须重新评价。近来Stadtler和Hartman二氏以睾丸的大小、小管的直径和原始精原细胞数目的变化为指标提出:小儿睾丸从生后就连续不断地生长,Salle、Hedinger和Nicole氏等又发现了新生儿每50个小管就有50～100个原始精原细胞。在这些进步的基础上,为了明确找出隐睾开始治疗的合理时间,作者再次检查了所有的组织标本。作者的评价标准是按Hedinger和Hosli的观点:在小管的成熟和小管的直径变化之外,以原始精原细胞含量为评价未降的睾丸功能的决定性指标。
In the previous report, based on a limited number of testicular biopsies, the authors agreed with Robinon and Engle’s opinion that the male gonads are quiescent until age 5 years. Today we have accumulated more histological data, this view must be re-evaluated. Recently, Stadtler and Hartman two’s testicular size, tubule diameter and the number of primitive spermatogonia as indicators: pediatric testicles from birth to continuous growth, Salle, Hedinger and Nicole’s again found that the newborn 50 small tubes have 50 to 100 primitive spermatogonia. On the basis of these advances, in order to clearly identify the reasonable time to start the treatment of cryptorchidism, the author re-examined all the tissue specimens. The authors’ evaluation criteria are based on Hedinger and Hosli’s view that, in addition to tube maturation and small tube diameter changes, the original spermatocyte content is a decisive indicator of undetectable testicular function.
