Circadian timing system plays a major role in a wide range of reproductive function. However it is plausible idea that other environmental and/or internal cue might be simultaneously participated in the optimal regulation of reproductive system. In the present study we extended the reverse feeding (RF) time regimen up to 8 weeks, then measured the general and reproductive indices of the animals. The animals of ad libitum feeding group (Control, CON) have free access to food for 4, 6 and 8 weeks, respectively. The day feeding animals (reverse feeding, RF group) have restricted access to food during daytime (09:00-18:00) for 4, 6 and 8 weeks, respectively. When the feeding schedules were over, key indices were measured. After 4 weeks and 8 weeks of feeding, body weights of animals were not significantly different. However, body weights of 6 weeks RF animals were significantly smaller than those of control animals (CON : RF = $333.46{pm}12.71$ g : $289.91{pm}8.31$ g, p<0.01). The blood glucose levels of 4 weeks RF animals were significantly decreased compared to the levels of control animals (CON : RF = $161.4{pm}2.7$ mg/dL : $176.7{pm}5$ mg/dL, p<0.01) while the levels of 6 weeks RF and 8 weeks RF animals were not different form those of control animals. Reproductive and non-reproductive tissue weights from 6 weeks RF group were significantly lowered than those from CON group (testis, CON : RF = $1.4714{pm}0.0174$ g : $1.3724{pm}0.0168$ g, p<0.001; epididymis, CON : RF = $0.3574{pm}0.0059$ g : $0.3243{pm}0.0068$ g, p<0.001; seminal vesicle, CON : RF = $0.1655{pm}0.0068$ g : $0.1328{pm}0.0054$ g, p<0.001; prostate, CON : RF = $0.3350{pm}0.0231$ g : $0.2528{pm}0.0143$ g, p<0.01). After 4 weeks and 8 weeks of reverse feeding, sperm counts in RF animals were markedly reduced than those in control animals[CON 4W : RF 4W = $121.17{pm}9.96;({ imes}10^6)$ : $50.86{pm}9;({ imes}10^6)$, p<0.001; CON 8W : RF 8W= $138.69{pm}9.8;({ imes}10^6)$ : $108.94{pm}4.22;({ imes}10^6)$, p<0.001]. Present study indicates that RF may induce an adaptable metabolic stress and cause impairment of androgen-dependent reproductive tissues. On-going longitudinal studies will allow a better understanding of the how does mealtime shift affect the reproductive function and exact nature of adaptation.
