Abstract
1. Male fiddler crabs, Uca pugilator, received injections of 5-hydroxy tryptamine (5-HT, serotonin). The crabs showed dose-dependent testicul ar development. 2. Like 5-HT, the 5-HT releaser fenfluramine and the 5 -HT potentiator fluoxetine induced testicular maturation also, but the 5-HT receptor blocker LY-53857 did not. 3. The data support the hypot hesis that 5-HT exerts this stimulatory effect on the testes indirectl y, by triggering release of gonad-stimulating hormone.
