第一种假说认为，LH对颗粒细胞的刺激作用终止减数分裂抑制因子流 向 卵母细胞 ， 从而 使 卵母细胞 隔 离 这些抑制因子并进而促使减数分裂恢复，第二种假设认为LH刺激颗粒细胞产生一种减数分裂诱导信号，该信号进而克服或者破坏减数分裂抑制因子的作用。 actazool.org | The second hypothesis is that LH stimulates the generation of a meiosis inducing signal by the granulosa cells that overcomes or destroys the meiosis arresting factor(s). actazool.org |
