Laurer's canal

Laurer's canal

Laurer's canal is a part of the reproductive system of trematodes, analogous to the vagina. In the Digeneans it opens from the dorsal surface of the worm, and in the Aspidogastreans ends in a blind ended sac. Laurer's canal may be used by the flukes during copulation, but more normally sperm enters the female system via the common genital atrium, (into which the uterus opens), either during copulation, or self-fertilisation.
