卵細胞內之空泡多為平滑內質網sER所形成
其成因可能與E2太高，Ca signal 異常有關
施行ICSI後胚胎之著床率較差

Figure 3. Appearance and growth of the sERCs in cultured oocytes. The denuded oocytes in which no sERCs had been seen were cultured for 2–5 days. A large sERC appeared after 4 days in the cortical area (A), and three medium sized sERCs appeared after 3 days (B). The light microscopic images (left) and the confocal images stained with DiI (right) are shown. An oocyte in which a medium sized sERC had been observed during the denuding procedure was cultured (C). The time course images of this oocyte are shown. The size of a growing sERC indicated by the arrows was measured during incubation (0–30 h).
