© 2015 Elsevier Inc. The proctodeal gland of the male Japanese quail produces thick foam that accompanies semen when it is transferred to the female. It is thought that this foam enhances fertilization by improving the motility of the sperm, but reports are conflicting because the effect of foam on sperm motility has only been assessed subjectively The velocity of individual sperm was not able to be measured accurately, variations were large, and small changes in motility could not be accurately evaluated. So, we tested the hypothesis that foam affects the motility of spermatozoa of Japanese quail by analyzing motility objectively using computer-assisted semen analysis and determining changes in sperm kinetics in the presence of different concentrations of proctodeal gland foam. The addition of 5% or 10% foam to the sperm suspension increased (P
