Early life exposure to environmental levels of the aromatase inhibitor tributyltin causes masculinisation and irreversible sperm damage in zebrafish Danio rerio. Artificial induction of functional sex-reversal in genotypic females of the medaka Oryzias latipes.

The experimental induction of sex reversal in species that do not undergo sex change in nature was first reported in medaka 1. Therefore, it was suggested that oocyte apoptosis plays a significant role in the testicular differentiation of juvenile zebrafish.

Then, cyst structures filled with different stages of spermatozoa-like cells, similar to those observed in the normal testis, were observed in sections from fadrozole-treated fish at 8 weeks after replacing the AI food with the control treatment. Download references.
