When sperm heads are injected into rat oocytes at the germinal vesicle stage the sperm heads remain intact until the germinal vesicle breaks down. Then they decondense but do not form pronuclei. This observation agrees with the results reported for in vitro fertilization of immature oocytes from rats, mice and hamsters.
当精子头部在生发泡期被注入大鼠卵母细胞时,精子头部在生发泡破裂之前保持完整。然后它们解聚,但不形成原核。这一观察结果与关于大鼠、小鼠和仓鼠未成熟卵母细胞体外受精的报道结果一致。
