Abstract/OtherAbstract:
|
Mouse oocytes were fertilized by intracytoplasmic sperm injection (ICSI) and reinseminated after the removal of zonae pellucidae at pronuclear stage or at the 2-cell stage. Although these oocytes were activated normally by ICSI, as evidenced by resumption of meiosis and cortical granule exocytosis, they did not develop oolemma block to sperm penetration. They could be penetrated by spermatozoa at pronuclear stage and even at the 2-cell stage. This supports the notion that incorporation of sperm plasma membrane into oolemma contributes to the changes in oolemma that block sperm penetration. |
