  1. Female llamas (n = 4 per group) were given whole seminal plasma (SP, positive control), Fractions A or B (isolated by hydroxylapatite column chromatography), Fractions C1 or C2 (isolated by gel filtration chromatography), or phosphate buffered saline (PBS, negative control).
  2. * No significant differences among groups.
  3. a,b Proportions with different superscripts are different (P < 0.03).
