Mean estradiol 17β (± sd) production by cumulus cell monolayers coincubated with spent media from immature (GV) or properly matured pig oocytes (M+H). Control wells were challenged with medium alone (for baseline E₂ production, TCM 199) or medium containing FSH (positive control, for gonadotropin-stimulated production). *P < 0.01 (Student t-test).
