Testicular Steroidogenesis and Locomotor Activity Are Regulated by Gonadotropin-Inhibitory Hormone in Male European Sea Bass
Fig 1
In vivo effect of sbGnih-1 and sbGnih-2 in male sea bass steroid plasma levels.
Plasma levels of testosterone (T)(A, B, C), 11-ketotestosterone (11-KT)(D, E, F) and 17α,20β-dihydroxy-4-pregnen-3-one (DHP)(G, H, I) were analyzed in sbGnih-1- (B, E, H) and sbGnih-2- (C, F, I) treated animals throughout the reproductive cycle. Vehicle implanted animals represent the control group (A, D, G). Values are expressed as mean ± SEM (n = 12–14). Different lower case letters indicate significant differences throughout the reproductive cycle within each condition (ANOVA, Student-Newman Keuls test, P<0.05). Asterisks (*) denote significant differences between Gnih-treated animals versus controls in a particular month (P<0.05).
