Abstract: In mammals,the melatonin secreted by pineal gland was modulated according to the photoperiod and season. The hypothalamic-pituitary-gonadal axis accepted the messages from melatonin and integrated both external and internal status and appropriately altered the activity of the GnRH. All these supported mammals to maximize reproductive success and avoid breeding during inappropriate conditions. Reproductive rhythm was formed and fixed in the process of long evolution in mammals and some genes were identified to be related with reproductive seasonality. This review briefly introduced the relationships between MTNR1A,MTNR1B and KiSS-1/GPR54 genes and reproductive seasonality in mammals.

Key words: reproductive seasonality; gene; polymorphism
