The effects of serotonin, dopamine, gonadotropin-releasing hormones, and corazonin, on the androgenic gland of the giant freshwater prawn, Macrobrachium rosenbergii.

Highlights: [•] The androgenic gland (AG) controls male reproduction in Macrobrachium rosenbergii. [•] The AG cells produce insulin-like androgenic gland hormone (Mr-IAG). [•] 5-HT and l-GnRH-III have stimulatory effects on the AG cell proliferation and Mr-IAG production. [•] DA and Crz have inhibitory effects on the AG cell proliferation and Mr-IAG production.
