Reproduction is one of the most important biological phenomenons among the organisms. A detailed knowledge about the mechanism(s) behind reproductive regulation will be helpful for us to understand this phenomenon in a better way. With the help of this knowledge we can generate new ideas which can able us to control the fertility of economically important species. Various mechanisms regarding the reproductive regulations have been studied. In the vertebrates, physiology of reproduction is actually controlled through the hypothalamo - hypophyseal gonadal (HPG) axis which comprises of higher brain center, hypothalamus, hypophysis and gonad. All the factors either extrinsic or intrinsic that affect the HPG axis can modulate reproduction. Among many of these factors, specific temporal phase relations of neural oscillations have been suggested in higher vertebrates (especially in some birds and mammals). In general, these temporal phase relationships are time dependent rhythmicity of neural/hormonal activity.
