• Resumen

  • In their recent comprehensive review in TREE, Wedell et al. [ 1. ] demonstrate convincingly that, consistent with theory, males have evolved a diverse suite of strategies to allocate sperm strategically according to the reproductive value that is associated with individual inseminations. As the authors point out, strategic sperm allocation by males has important repercussions for female fitness. When a male limits his sperm investment in a female to save sperm for novel partners, he might inseminate too few sperm to fertilize all of her eggs, thus limiting the reproductive success of individual females [ 1. ], or forcing females to seek more copulations.
