Effect of Photoperiod and Melatonin on Volume and Cellular Parameters of Testis in Pinealectomized Rats

Mammalian reproductive axis is regulated by the combination of three fundamental tissues of neuroendocrine system including hypothalamus, hypophysis and gonads. In recent years, pineal gland has been included in this axis. The aim of the present study was to investigate the effect of 12L (Light):12D...

The aim of the present study was to investigate the effect of 12L (Light):12D (Dark) photoperiod and melatonin administration (0.5 mg/kg/day; subcutaneously) on testicular volume and cellular parameters of testis at the pinealectomized (PE) rats.
