'These results support the hypothesis that mating behaviors in hermaphrodites are not merely degenerate female behaviors but instead enhance their genetic fitness: young hermaphrodites minimize genetic dilution by avoiding mating while self-sperm are present but can then increase total progeny number by allowing cross-fertilization after self-sperm are depleted'
