- 摘要：
- e about the exact stage(s) at which such benefits are gained. Here, we measure whether offspring fitness is influenced by mechanisms operating solely between sperm

- 摘要：
- o measuring sperm velocity of the individual males in the individual ovarian fluids. We found large effects of males, but no effect of females (i.e., eggs

- 摘要：
- of gametes produced, and gamete quality (sperm velocity and egg mass) of males and females. Our results reveal pronounced differences between the sexes in age

- 摘要：
- In some taxa, males perform multiple ejaculations, which may function in sperm competition or in maintaining a baseline density of spermatozoa

- 摘要：
- tilization success increased after FSS, driven by a change in male paternity share across broods. This change was positively associated with sperm velocity (measured before FSS
Data from: Sperm competition, but not major histocompatibility divergence, drives differential fertilization success bet
