This study aimed to determine the effect of taurine on the enhancement of the spermatogenetic process in male mice (Mus musculus) induced by paraquat (PQ). Twenty-five male mice (Mus musculus) aged 2-3 months with a bodyweight of around 35 grams were divided randomly into five groups. The K + and the treatment group (P1, P2, and P3) mice were induced using PQ. PQ was given intraperitoneally (IP) twice a week for 21 consecutive days at a dose of 30 mg/kg BW. Two hours after the administration of PQ, P1, P2, and P3 groups were given taurine at a dose of 250, 500, and 1000 mg/kg BW/day for three weeks (Heidari et al., 2019). K- group was given distilled water (IP) only. On day-29, mice were sacrificed for testicles histopathological preparations with hematoxylin-eosin staining. Results showed that the mice exposed to PQ only (the K+ group) had a reduced spermatogenesis score compared to those of the K- group (p <0.05).  Taurine treatment on PQ-exposed mice was followed by an increase spermatogenesis score. The optimal curative dose of taurine was 500 mg/kg (P2 group). However, a higher dose (1000 mg/kg BW) of taurine resulted in a decline in the spermatogenesis score than those of at the 500 mg/kg. It could be concluded that treatment with taurine could enhance the spermatogenetic process of male mice (Mus musculus) induced by PQ.
