The serotonin and prolactin content of the blood in women with idiopathic galactorrhoea.

In two groups of women--one group of 12 normal-mammary-gland controls and another group of 10 idiopathic galactorrhoea patients--we determined the blood concentration of serotonin and prolactin. The obtained data show no significant differences between the studied groups either in serotonin or prolactin levels i.e., serotonin is not implied in the pathogeny of idiopathic galactorrhoea. The data are confirming our previous results concerning the functional correlations between the serotonin system and prolactin release, as well as the data obtained by other authors on the normal values of prolactin in idiopathic galactorrhoea.
