Ipasaphor
The ipasaphor was a yellowish mucilaginous substance secreted from the palms and fingers of Ocampa females who had begun the elogium. Appearing very soon after the other signs of elogium (such as the appearance of the mitral sac), the ipasaphor made the mating bond possible.

With the appearance of the ipasaphor, mating needed to begin within approximately fifty hours. The female and her mate had to remain bonded for six days to ensure conception.

As elogium only occurred once in Ocampa females, it was critical that the rolissisin be performed soon after the appearance of the ipasaphor, and mating soon after. ()
