|According to the WHO:
- If the mother is circumcised
- For fetal distress
- For complications (breech, forceps, etc.)
In the first case, isn't always necessary - it depends on what type of circumcision and how much the mom has been sewn up.
In the last instance, I think a lot of it depends on the skill and training of the provider and whether or not the baby is in distress. I have seen a vacuum extraction that didn't involve an episiotomy, but I think forceps might be more invasive. And somebody who is trained to attend breech births probably would not find it necessary to cut a woman birthing a breech baby.
