Dopaminergic neurons in the brain and dopaminergic innervation of the albumen gland in mated and virgin helisoma duryi (mollusca: pulmonata). [PDF]
BMC Physiol, 2001 Dopamine was shown to stimulate the perivitelline fluid secretion by the albumen gland. Even though the albumen gland has been shown to contain catecholaminergic fibers and its innervation has been studied, the type of catecholamines, distribution of fibers and the precise source of this neural innervation has not yet been deduced.

Effect of Bisphenol A (EDC) on the reproductive potential of Helisoma duryi (Wetherby, 1879)
Egyptian Journal of Aquatic Biology and Fisheries, 2015 It has been claimed that bisphenol A (BPA) induces some reproductive potential disorders in the freshwater gastropods worldwide. The adult fecundity and egg hatchability as well as histological effects and embryonic deformities on the exotic freshwater snail Helisoma duryi have been studied to explore the superfeminization phenomena. The results of the
