Prolactin induces regional vasoconstriction through the beta2-adrenergic and nitric oxide mechanisms.

abstract：:Puberty is a developmental period characterized by a broad range of physiologic changes necessary for the acquisition of adult sexual and reproductive maturity. These changes mirror complex modifications within the central nervous system, including within the hypothalamus. These modifications result in the maturation ...
