Mature oysters operate a sexual reproduction. The Hollow Oysters Crassostrea gigas are oviparous, thus the ovule fecundation with spermatozoon happens in the water influenced by the current. This is an alternative sexuality. Oysters may enjoy the rule of the male or the female and change their sexuality the year after. Some hermaphrodite may subsist after the growing step but it is rare.
