Definition of hemipenis in English:



  • Each of the paired male reproductive organs in snakes and lizards.

    • ‘Sharks do have paired structures for injecting sperm, called hemipenes.’
    • ‘Despite these anatomical differences, amniote penises and hemipenes share some basic similarities: they are all more or less cylindrical, and they are all hydrostatic.’
    • ‘We sexed each snake by probing its cloaca to detect the presence of hemipenes.’
    • ‘Our studies on gartersnakes (Thamnophis sirtalis parietalis) reveal significant morphological asymmetry in this system: testes, kidneys, and hemipenes on the right-hand-side of the body are larger than those on the left.’
    • ‘Sex was determined by everting the hemipenes of males.’
