Evolution of cadmium effects in the testis and sperm of the tropical fish Gymnotus carapo

Highlights • The present study shows the Cd effects in the testes and sperm of Gymnotus carapo. • Testis morphology was altered after exposure to progressive doses and exposure times. • Cd affected the germ cells in different stages of differentiation. • Alterations in sperm count and morphology wer...

Zusammenfassung:Highlights • The present study shows the Cd effects in the testes and sperm of Gymnotus carapo. • Testis morphology was altered after exposure to progressive doses and exposure times. • Cd affected the germ cells in different stages of differentiation. • Alterations in sperm count and morphology were also observed. • The work characterizes the Cd-induced pathogenesis in the male reproductive system.
