Figure 5From: Pheromonal bile acid 3-ketopetromyzonol sulfate primes the neuroendocrine system in sea lampreyDifferential effects of synthesized pheromone component on plasma and forebrain lGnRH-I concentrations in male sea lamprey. (A) Plasma lGnRH-I concentrations showed various effects after 10-10Â M 3kPZS exposure. Exposure to 10-10Â M 3kPZS increased lGnRH-I concentrations in the forebrain (B) but had no effect in the brain stem (data not shown).Back to article page
