The existence of different stages of postnatal activities in Leydig's cells, as demonstrated in hormone studies, appears to be fully admitted. Such occurrence should have repercussions on the population of those elements primarily entrusted with their production, either in the number of elements or their activities. The present article studies Leydig's cells rate in Wistar rats over the postnatal stage, from birth to adulthood. During this postnatal stage, Leydig's cells population does not actually disappear. There is a decrease immediately after birth and up to the age of 21 days when gonadal drop occurs in this species, and from there on a considerable increase takes place for in a two-month period they multiply by ten. On the other hand, it is highly surprising the great speed of testicle growth up to the age of 60 days, reaching maximum size at 90 days. The increase is due to the growth of the tubular compartment.
正如激素研究所示，睾丸间质细胞产后活动存在不同阶段，这一点似乎已得到充分认可。这种情况应该会对主要负责其产生的细胞群体产生影响，无论是细胞数量还是细胞活性。本文研究了从出生到成年的产后阶段Wistar大鼠的睾丸间质细胞比率。在这个产后阶段，睾丸间质细胞群体实际上并未消失。出生后立即减少，直到该物种出现性腺下降的21天龄，从那时起，在两个月的时间里，它们大量增加，数量增加了十倍。另一方面，令人惊讶的是，睾丸在60天龄之前生长速度极快，在90天达到最大尺寸。这种增长是由于管状结构的生长。
