Role of steriod hormones in sex change of protogynous wrasse

Fish Physiology and Biochemistry volume 28, pages 149–150 (2003)Cite this article

Abstract

The endocrine mechanisms of sequential hermaphroditism were investigated in protogynous wrasse, Halichoeres trimaculatus. Administration of aromatase inhibitor and androgen both stimulated sex change, while estrogen suppressed the induced sex inversion. The results suggest that removal of estrogen is a key step to initiate sex change.
