| we used ICSI but very few eggs fertilized (severe MF)-- has this happened to anyone else? did you try anything or change anything and get a high amount of fertilization in another cycle? appreciate any thoughts. |

| No identified male factor but only two of six fertilized. But one of them was a keeper! |

| Fertilization with ICSI has more to do with egg than the sperm. Sperm's importance gains after the fertilization. Were all 6 eggs mature? |

| Actually my re at Cornell (Owen davis) says fertilization failure is generally tied to problems with sperm rather than egg |

| Depends, if the sperm have high DNA fragmentation (you can test for this) and ICSI was used, then it probably is the sperm. |

Yes, and they were young donor eggs, so it seems like it could have been the sperm. |

We have severe male factor and used ICSI and had consistently a 50% or 60% fert rate but always only a few made it to day 3 or 5. Had 3 three day transfers (never any 8 cell) and two five day transfers. In our experience the probable issues w the sperm came through after fertilization. How many of
Yours made it to day 3 or 5? |
