Combined Effect of Environmental Factors and Nutritional Status on the Weight of Testis and Testicular Total Proteins in Albino Rats

Natural selection has provided the mammal with a rich variety of signaling systems, each of which couples environmental variation with appropriate neuroendocrine responses. Therefore the complicated processed of mammalian reproduction occurs in harmony with exhisting dietary factors and different aspects of physical environmental. In recent years the study of low nutrients and their metabolism as well as various environmental factors effect reproductive processes has gained a great momentum., several research articles reveal that environmental factors and nutritional status directly or indirectly modulate reproduction in mammals. In general the male reproductive system show much more resistance to malnutrition and photoperiodic length of environmental factors alone influences the seasonal changes in testicular volume in sheep as earlier reported by Martin (1984).
