ABSTRACT
Plane of nutrition is intimately involved with maintenance of the functional integrity of the vertebrate reproductive system. Inadequate nutrition or nutrient deficiency as well as overnutrition and excess food have deleterious effects on reproductive performance. The mechanisms of action under these conditions may be at least twofold, either through a direct effect on the reproductive organs themselves or through alterations in the synthesis and/or release of the reproductive hormones. In the latter indirect mechanism, hormone levels might in turn regulate or influence nutritional requirements so a type of feedback is established.
