Background: Search for an effective, feasible, and safe male contraceptive has been one of the major public health challenges. The present contraceptive methods are either permanent or impractical. Herbal methods are considered safe, and thus, their acceptability is higher than other prospective methods. Aims: In the present study, oral administration of methanolic extract of Butea monosperma (Lam.) Taub. flower was investigated for its potential role in the modulation of fertility in male albino rats. Materials and methods: Healthy male albino rats were randomly distributed into three groups, i.e., a control and two groups administered with 50 and 500 mg/kg body weight/day of methanolic extract of B. monosperma flower for 30, 90, and 180 days, respectively. Fertility records were maintained throughout the experimental period. At the end of experiment, animals were sacrificed and the weight of reproductive organs, sperm characteristics, and histopathology of testicular and epididymal tissues were evaluated. A 45-day withdrawal period was also investigated for parameters as described above for each group. Results: A 40% decline in fertility rate was evident in rats administered with 500 mg/kg of B. monosperma flower extract for 180 consecutive days. A significant reduction in testicular and epididymal weight was observed in these animals. Sperm count, motility, and viability were also reduced significantly in animals treated for 180 days. Histological evaluation of testicular cells indicated distortions in germ cell arrangements at various stages of spermatogenesis. Following 45 days of withdrawal, the resumption of normal functional and histological characteristics was apparent. Conclusion: Based on the abnormalities present in the sperm characteristics and damages in testicular histology, it was confirmed that methanolic extract of B. monosperma flower contain antifertility potential.
