Sperm choice and the female reproductive fluid: paternity biases after matings

Abstract:
The role of non-gametic components of the ejaculate, the seminal fluid, in fertility and sperm competition is now well established. Surprisingly, however, we know far less about the non-gametic component in females, the female reproductive fluid (FRF). This fluid exerts differential effects on a range of sperm traits, including chemoattraction and sperm velocity, and has been therefore pointed out in recent years as a widespread mechanism for cryptic female choice, with an important role in determining the outcome of postmating sexual selection. I’ll cover what we know so far and the new avenues for research on FRF in the context of sexual selection and sperm choice.
