Both A and B pose challenges to the hypothesis that increased sperm production in bats is solely due to female promiscuity. Female bats have the ability to selectively eject sperm from certain males after mating and also have control over which male they mate with last, which may affect the likelihood of fertilization with a particular sperm. Thus, other factors aside from female promiscuity may play a role in the evolution of increased sperm production in bats.
