Objective: Carob (Ceratonia siliqua L.) is an evergreen tree with fruits that have potent antioxidant activity. The aim of this study was to investigate alleviative effects of carob fruit hydro-alcoholic extract (CFHAE) against reproductive toxicity induced by lead (Pb) in male mice. Material and Methods: Forty-two NMRI adult male mice were randomly categorized into 7 groups (N=6). Group ...

Design/methodology/approach: Description main hormones and their application in sheep protocols. The subjects are reviewed based on academic references as well use protocols at Sheep Goat Reproduction Laboratory Colegio de Postgraduados, Mexico. Results: Hormones, socio-sexual s...

Male Japanese black bears (Ursus thibetanus japonicus) have an explicit reproductive cycle. The objective of this study was to clarify the variation of plasma testosterone, FSH, inhibin, LH levels and testicular gonadotropin receptor mRNA expression of male bears associated with their testicular activity. Notably, this study investigated peripheral FSH concentration and localization of gonadotr...

Steroid sex hormones produce physiological effects in reproductive and non-reproductive tissues, such as the brain. In brain, receptors are expressed cortical, limbic midbrain areas modulating memory, arousal, fear motivation between other behaviors. One neurotransmitters system regulated by is dopamine (DA), where during adulthood, promote neurophysiological behavioral on DA systems tuberoinfu...
