A study of reproductive behavior has been conducted on long tail macaques (Macaca fascicularis) which have been sterilized by a vasectomy method at Yayasan Inisiasi Alam Rehabilitasi Indonesia (YIARI), Bogor. The purpose of the study is to observe the influence of vasectomy to reproductive behavior of those animals. Observation was conducted on 3 (three) male macaques (the code names are: Jantan1, Jantan2 and Jantan3) which were captive-housed with 2 other female macaques (the code names are: Betina1 and Betina2). The method of observation is a combination of scan sampling and ad libitum methods with 5 (five) minutes intervals without pause. Daily observation were done from 08:00 am to 03:00 pm for 14 days in August 2016 and brought about 1,008 sample points. Results showed all males still actively performed reproductive behavior with Jantan1 in dominant position to all females compared to other males. Male Mounts (MM) of Jantan1 (111 times) was found higher than other males (Jantan2 10 times and Jantan3 21 times). We resume that reproductive behavior was still found in all males because vasectomy methods did not affect spermatogenesis process therefore the hormonal system remain in normal condition. There are differences in the frequency of males' reproductive behavior to all females since all males preferring to mate with Betina1 instead of Betina2. The Female Refuse Sex behavior to males was found higher in Betina1 (111 times) than Betina2 (7 times) as Betina1 assumed to be dominant than Betina2.
