Figure 4From: Mouse oocytes fertilised by ICSI during in vitro maturation retain the ability to be activated after refertilisation in metaphase II and can generate Ca2+oscillationsMean number of [Ca2+]i transients generated in MII oocytes in response to spermatozoa during 60 min after fertilization. Differences between "ICSI + IVF" variant and "sham+IVF" and "IVF" variants are statistically significant (p < 0.05).Back to article page
