Comments on injection scenes:
1 - this is a polyspermic egg (2 or 3 fertilization cones) and you probably shouldn't inject near the fertilization cone like this because it may damage the sperm nucleus / sperm aster.
2 - injected in the early period (just after the ruffled stage). Needle penetration seems to cause disruption
3 - early period, needle removal causes disruption
4 - needle removal causes disruption
5 - probably injected too shallow
6 - probably injected too shallow
7 - needle didn't penetrate, injection doesn't go into embryo
8 - injection of an older egg (>7 min after fertilization) - needle removal causes disruption
9 - puncture causes disruption
10 - success! But this isn't necessarily typical, the needle entry is somewhat more difficult than usual here. Unfortunately, these scenes don't show when the picospritzer was activated. It seems to work better if you wait a few seconds after the injection is finished before pulling out the needle.
