The objective of this study was to monitor the effect of exposing hatching quail eggs to high light intensity on testicular function Quail eggs were distributed into four groups; dark application during the 18-day incubation period (C), light application during the 18-day incubation period (L), 5 days of light + 13 days of darkness (5L), and 5 days of darkness + 13 days of light (5K) and incubated. After the hatch, 40 chicks were selected from each group and placed in rearing cages. On day 42 after hatching the quails were weighed and their testes were removed and then embedded in paraffin. The blood glucose level of the 5K group was higher than the blood glucose level of the L group, but there was no statistically important difference (P<0.05) between the L, C, and 5L groups. The diameters of seminiferous tubules were bigger in the 5L group as compared with the L group. The groups treated with light had bigger tubule diameters than the control group. The number of Sertoli cells was significantly lower in the C group. Incubating quail eggs under five days of darkness and thirteen days of light have a favorable effect on post-hatch male fertility potential.
