WebOct 1, 2024 · Mutations in genes involved in formation of the sperm tail cause motility defects and thus male infertility. Therefore, it is crucial to understand the protein networks required for sperm differentiation. Sperm motility is produced through activation of the sperm flagellum, which core structure, the axoneme, resembles motile cilia. WebEukaryotic Flagella. In Eukaryotes, like sperm cells, the flagella is closely similar to the cilia, which is a hair-like strand responsible for sensory functions. They are similar structurally.
