In vivo induction of human chorionic gonadotropin by osmotic pump advances sexual maturation during pre-spawning phase in adult catfish

Highlights • hCG induction by osmotic pump advances sexual maturation. • Elevated levels of transcripts related to gonadal growth after hCG treatment. • Significant increase of hormone levels after hCG induction. • Histological analysis confirms hCG-induced advancement of gonadal maturation.
