Melatonin Effect (Under Alternating Light and Injection) On Testicular Tissue

Dr. Maen T Idell

Abstract: The research experience was designed according to the complete random sectors. The applied method was used to determine the relationship between the exposure of the alternating light period and the environment of the organism, the synthesis of melatonin by the pineal gland, and the effect on the reproductive efficiency of male laboratory animals (hamsters). Through a tissue study. The study was conducted at two stages of sexual age (before and after puberty), and two periods of alternating and neutral lighting. The effect of injection of melatonin externally under the skin, it was found that the different concentrations were 6.25 g - 12.5g - 25g with the concentration of the hormone melatonin internal origin produced by the pineal gland to its lower limit) at the previous two stages, on the male reproductive efficiency of this animal. It was found that exposure to long photovoltaic periods had an effect on increased body weight, especially in post-puberty sex, and exposure to long periods of light, has an impact on the male reproductive system, and structure of tissue, and the broadness of the glands of sperm. And large in the cells of Sertoli, and change the form of the interstitial cells to the shape of the spindle, and increase the brightness of the channel conveying the sperm, and the thickness of the thickness of the muscle layer. The hormone melatonin injected has an inhibitory effect on body weight, proportional to the amount of concentration, and the stage of injection, as well as the hormone melatonin injected has an inhibitory effect on the size of the male reproductive system. Atrophy in the testis, lack of dimensions, weight loss, inhibitory effect of the structure of tissue. Appeared larger in the second group, and the injected hormone had an effect on the tissue structure, stenosis of tubular and epidermal ducts and ducts of the sperm. Causes of the disappearance of sperm cells with n1 pigment, and the small size of the cells Sertoli and interstitial cells and increase the thickness of the muscle layer.
