Number of Leydig cells (HSD3B immunopositive)/testis (top panel), and corresponding changes in their nuclear diameter (bottom panel) during peri-pubertal development in the rhesus monkey. While HSD3B positive cells were absent in the mid-juvenile (MJ) group, their number gradually increased during subsequent pubertal development resulting in a marked elevation in adulthood (AD) (top panel). A significant increase in nuclear diameter occurred during the late-juvenile (LJ) - early pubertal (EP) transition but stabilized thereafter (bottom panel). Note, the nuclear diameter was not determined in the MJ group (bottom panel) since HSD3B immunopositive cells were absent. MP, mid-pubertal. a, P≤ 0.05 from the remaining groups.
