In the present study, nine sexually matured Arabian stallions (5-15 years old) were used for recording the sexual behavior. The obtained results revealed that, time to the first mount and latency to mount (seconds) were insignificantly shorter in the Arabian stallions during summer season at 5 years old and were longer during winter season at 15 years of age. Latency to erection (seconds) was insignificantly the shortest during summer at 5 years old and the longest during autumn season at 10 and 15 years of age. Latency to ejaculate (seconds) of the Arabian stallion was insignificantly shorter at 5 years and 15 years old during spring and summer than winter and autumn seasons at 10 years. Number of mounts per ejaculation of the Arabian stallions was significantly (P<0.05) less during spring and summer, while significantly (P<0.05) bigger during winter and autumn seasons. On the other hand, Number of mount per ejaculate was insignificantly lower in the Arabian stallions at 5 years than at both 10 years and 15 years old.
