Background: Sperm motility is a key parameter of male fertility in both animals and humans. We know that sperm parameters change with many parameters such as diet and nutrition, male age or mitochondrial haplotype but also with the medium the sperm is kept in. Be the first in the world to investigate sperm motility in insects in your thesis. More interesting (i.e., relevant for a MSc project) is the question how sperm motility can evolve through males if it is driven by sperm mitochondria but mitochondria are only inherited through females. And it is not clear how well the mitochondria work in different nuclear background. Interested? Get in touch.
