Effect of an increase in environmental temperature on testicular androgenesis and spermatogenesis in toad (Bufo melanostictus) during hibernating season

Activities of key testicular androgenic enzymes [Δ5, 3β-hydroxysteroid dehydrogenase (Δ5, 3β-HSD) and 17β-hydroxysteroid dehydrogenase (17β-HSD)], plasma levels of testosterone, and testicular gametogenic activities were studied in heat-exposed adult male toads during hibernating season for two consecutive years. Exposure of toads to an elevated environmental temperature for 14 and 21 days resulted in significant elevation of […]
