Abstract: Female smooth newts begin egg deposition in spring after hibernation even if they have not been inseminated. All these eggs are unfertilized. This indicates that the sperm from the previous years are either not retained in the seminal receptacles or are incapable of fertilization. A large proportion of females do not lose receptivity after the first insemination and may collect several spermatophores during the egg-deposition period. There seems to be a positive correlation between the number of eggs deposited and the number of spermatophores transferred.
