Input: Abstract: We have demonstrated an in vitro secretion of inhibin by human OCCC, not related to subsequent egg cleavage. A putative signal, released by OCCC, that could modulate inhibin secretion by granulosa cells has not been discovered. Inhibin secretion by OCCC has no predictive value concerning the further fertilization and cleavage of the oocytes.

Inhibin concentration in the culture media of human oocyte-cumulus-corona cell complexes is not related to subsequent embryo cleavage.
