Shah博士在幼体发育早期没有发现任何睾丸酮受体；这和在胚胎测试中，发育十三天后的胚胎才开始出现睾丸酮激素现象相符合。
Dr Shah could not find them earlier in development either, such as just after the fetal testes first started putting out testosterone in a 13-day-old embryo.
目的：以人胎儿睾丸组织为供体，免疫缺陷小鼠为受体，研究人类睾丸生精细胞异种移植后的继续发育情况。
Objective: To investigate the development of xenografted primitive human germ cells by using fetal testicular tissues as donor tissues and an immunodeficient mouse as the recipient.
前三个发育阶段睾丸精原细胞HSP70阳性率比较在统计学上有显著性差异（P＜0.01），其阳性细胞率在新生猴期最低，童猴后期最高。
There was significant difference(P<0.01)in the ratio of HSP70-positive spermatogonia before puberty, which was lowest in neonatal and highest in late infantile.
