Summary In the mouse spermatogenesis appears to begin at the time of weaning. The volume of the interstitial cell nuclei remains fairly constant until the age of 15 months, when there is a remarkable increase. The absolute number of interstitial cells increases up to the age of 6 months, after which there is a slight decrease. As the number of interstitial cells relative to the tubules is ten times greater about the time of birth than at any other age, criticism of the iterstitial cell theory based on purely relative figures may be dismissed.
