Trauma or hemorrhage

In IVF, there is a minimal risk of traumatizing internal organs or major blood vessels during oocyte retrieval. However, this risk practically negligible in experienced hands and when all clinical precautions have been taken. Also, small hemorrhage is possible to be caused by the passing of the oocyte retrieval needle through the vaginal wall. However, it is small, harmless and stops after the oocyte retrieval without complications.
