Cyclic AMP and Oviduct Contractility
Available evidence indicates that the motility of the oviduct is markedly influenced by adrenergic hormones and ovarian steroids (Coutinho, 1973). The relationship between these two regulatory mechanisms is thought to play an important role in the control of ovum transport. Although the effects of the ovarian steroids on the oviduct are not as striking as those on the uterus, there is a tendency to consider estrogens as activators and progestins as inhibitors of oviduct contractility (Coutinho, 1973). Ovarian steroid hormones also influence the reactivity of the oviduct to adrenergic compounds. Estrogens render the oviduct more sensitive to the α-adrenergic effects of catecholamines, while progestins apparently potentiate the response of the oviduct to β-adrenergic activation (Coutinho et al., 1971; Coutinho, 1973).
