Mate Choice and Genetic Quality: A Review of the Heterozygosity Theory (2007, background): “(3) Experiments where sperm velocity of different male Arctic charr (Salvelinus alpinus) was measured in the ovarian fluid of different females, showed a highly significant male–female interaction, suggesting that females can differentially stimulate sperm depending on male characteristics (Urbach e”
