From: Pheromonal bile acid 3-ketopetromyzonol sulfate primes the neuroendocrine system in sea lamprey
Sex difference in steroidal responses after exposure to synthesized pheromone component in sea lamprey. Exposure to 3kPZS increased plasma 15α-hydroxyprogesterone (15α-P) concentrations in immature male but not in immature female sea lamprey. Δ15α-P = (post-treatment 15α-P level) - (pre-treatment 15α-P level). * Statistically different from 0 h control group (p < 0.05).
