Chronic Ethanol Feeding Impairs Human Chorionic Gonadotropin-Stimulated Testicular Testosterone Responses of Dogs1

Abstract
Total calcium concentrations of cumulus enclosed oocytes in the rat were studied during PMSG-induced LH release. The concentration of total calcium in cumulus enclosed oocytes increased concomitantly with increased serum LH up to and including 53 h after PMSG treatment; thereafter calcium level decreased. These increments in calcium concentrations and serum LH levels occurred at a time of an increase in germinal vesicle breakdown.
