Inseminated Drosophila females show two newly released behaviors ; a high rate of oviposition and mating reluctance. Using X/O sterile males, factors affecting these behaviors were confirmed to be contained in the secretion of the male accessory gland. Sterile females showed a remating rate similar to that of fertile females. This suggests that the remating of females is related neither to the number of eggs ovulated, nor to sperm stored in the female reproductive organs. The number of eggs laid and the remating rate of females can be determined by the quantity of secretion from the male accessory gland, which was supposed to have been introduced along with the sperm into the female reproductive organs. Sperm transfer and fertility of the sperm were not found to correlate with the quantity of secretion from the male accessory gland.
