[Serotonin contents in the hypothalamus of adult males, females and males castrated during the neonatal period].
The aim of the present work was to study the character of the change in serotonin level in the anterior and medial basal hypothalamus of adult rats after the effect of testicular hormones had been switched off on the first day of postnatal life. It was shown in our work that in males serotonin level was significantly lower than that in females by 67 and 46% in the anterior and medial basal hypothalamus, respectively. Castration of newborn males resulted in a significant increase in serotonin level in both anterior and medial basal hypothalamus-up to the level observed in females. It is supposed that the male sex hormones affect differentiation of serotoninergic system of the brain.
