Apossible role of Oxytocin on spermatogenesis and steroidogenesis in mouse: An approach towards
development of precocious puberty

The aim of this study was to evaluate the effects of Oxytocin (OT) treatment on the testis of mice. OT treatment produced
significant changes in the spermatogenic and steroidogenic activity in the pre-pubertal mice. The mice treated with OT
showed increased proliferation of germ cells as indicated by increased accumulation of spermatocytes and round spermatids
in the seminiferous tubules. Dose-dependent increase in expression of Oxytocin Receptor (OT-R), Proliferating Cell Nuclear
Antigen (PCNA) and Androgen Receptor (AR) proteins were observed in the testis of OT treated mice; when compared with
the control further supports the role of OT in spermatogenesis. The pre-pubertal mice treated in vivo with increasing dose of
OT showed significant increase in testosterone synthesis due to stimulatory effects of OT on testicular 3 beta HSD activity and
increased expression of Steroidogenic Acute Regulatory protein (StAR) and Luteinizing Hormone (LH-receptor) proteins.
Further, the in vitro study showed that OT, either alone or together with LH, also promotes testosterone synthesis and StAR
level in the testis. The OT treatment also affects testicular expression of BCL-2 protein, which may be important for germ cell
proliferation and survival. This study, thus suggests the role of OT in regulating testicular activity of pre-pubertal mice to attain
precocious puberty.
