Thaw for 3 minutes in an ice bath.
Wipe off ice that will form around the outside of the ampule.
Dry thoroughly.
Pop the top off...some are pre-scored and are fairly easy, some will need to be scored with a glass cutter in order to snap them off.
If you have the old bulb and pipette setup use that. The last one that I did, I used a hard plastic infusion pipette with a syringe.
Draw up semen into pipette and AI.
Note: Be careful around the thaw bath and when snapping the top off. If ampule was improperly sealed, ampules can blow up and shards of glass can fly.
