Table 1 Mouse oocyte in vitro maturation and fertilization

From: Mammalian oocytes are targets for prostaglandin E2 (PGE2) action

  Vehicle (%) PGE2 (%)
MII at 16 hours 53 69
MII at 18 hours 95 84a
Fertilization (2 cells) 71 71
Blastocyst 57 63
Hatched blastocyst 29 37
  1. Each observation represents the percentage of all oocytes in the indicated treatment group. Oocytes were pooled from 2 animals, n = 36-69 oocytes per treatment group. aPercent of cohort which progressed to MII by 18 hours was lower with PGE2 treatment, p < 0.05 by Fisher's exact test.
