Histology Observation, Anatomy Of Male Reproductive Organ In Slow Lories (Nycticebus coucang)

In male reproductive organs, testes play an important function. The histological structure of reproductive organ can also be used to determine the species. This study used the male reproductive organ of Nycticebus coucang which is distributedin Sumatra and adjacent islands. Materials examined were testicle, baculum and sperm, through histological evaluation. The study showed that histological specimen can be used to identify composition of tubuli seminiferous, including spermatosit primer, spermatosit sekunder, spermatid, and spermatozoa. Baculum length from the tip of anterior to posterior was 16.68 mm, and width from lateral of left to right was 3.45 mm and sperm length was 1.2-1.6 mm. Zoo Indonesia, 2014, 2, 84-91
