P < 0.05 compared to wild-type;

**

P < 0.001 compared to wild-type (unpaired Student’s t-test).

Mouse sperm were collected from the cauda epididymis unless otherwise noted.

Only spermatozoa with head and flagellum attached were counted for motility measurements.

Periaxonemal defects of the sperm flagellum were counted in EM micrographs of tissue cross-sections.
