[Sex steroid hormones and brain serotonin in the estrous cycle of silver foxes].
A significant increase in hypothalamic serotonin and estradiol levels was found in silver foxes during proestrus. During estrus, the plasma estradiol concentration was reduced and a significant increase in progesterone level was correlated with a decrease in the brain serotonin content. The data obtained suggest that the brain serotonin plays a mediating role in the control of ovarian hormonal activity and ovulation in silver foxes.
