The testicular measurement is important criteria for experimental researches especially in toxicological studies and the prediction of spermatogenesis. In light of this knowledge, we aimed to estimate and compare these parameters in two different kinds of cattle breeds. The gross anatomical measurements were performed by vernier caliper, volume of the testis was estimated by Cavalieri method and seminiferous tubule diameter was measured on the histological sections by software-loaded computer attached to microscope. The mean testis weight, length, width, volume, and tubule diameter of the Simmental bulls and the Holstein bulls measured as 316 g, 12.1 cm, 6.9 cm, 295 cm3 and 226.68 µm and 299 g, 12.1 cm, 6.8 cm, 285 cm3 and 223.44 µm, respectively.

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 (Dark) photoperiod and melatonin administration (0.5 mg/kg/day; subcutaneously) on testicular volume and cellular parameters of testis at the pinealectomized (PE) rats. For this aim, twelve adult rats were firstly pinealectomized and then divided into two groups as GI and GII randomly. The GI rats served as control group and received only normal saline, whereas GII rats were the melatonin administered group. It was found that the total testicular volume,... |
