Male age influence on fecundity and fertility has been studied in monomorphic (inversion free) and polymorphic (with inversion) strains of Drosophila ananassae. It was noticed that in both monomorphic and polymorphic strains, females mated to old males showed greater fecundity and fertility than females mated to young or middle aged males. Thus, in D. ananassae male age effect on fitness is ind...

These findings represent the first report in any organism of lifespan extension ...
