Alteration in molecular markers of oocyte development and intersex condition in mullets impacted by wastewater treatment plant effluents

Highlights • Intersex mullets were described in two populations inhabiting downstream WWTPs. • Up-regulation of vtga was detected in both mullet populations. • Transcription of sex related genes showed impaired gametogenesis in mullets from Gernika. • Xenoestrogenicity and exposure to EDCs was demon...

Zusammenfassung:	Highlights • Intersex mullets were described in two populations inhabiting downstream WWTPs. • Up-regulation of vtga was detected in both mullet populations. • Transcription of sex related genes showed impaired gametogenesis in mullets from Gernika. • Xenoestrogenicity and exposure to EDCs was demonstrated in both mullet populations.
