Short answer...There aren't any!
At least, none that have been clearly documented.
Scientists at the National Institutes of Health in the US have very
recently (March 2006) looked into this very question. You can see the
outcome of their efforts here:
NIH State-of-the-Science Conference: Cesarean Delivery on Maternal Request
Note that the second question (of the four questions addressed) specifically asks:
--What are the short-term (under 1 year) and long-term benefits and
harms to mother and baby associated with cesarean delivery by request
versus attempted vaginal delivery?
Any identifiable risks to the infant from either method of delivery
are largely due to the time of delivery, and the fact that some
cesarean deliveries appear to occur too early to allow for full
development in utero.
However, for the long-term risks, the NIH scientists were unambiguous
in their need to be vague:
"Neonatal Outcome Which Favors Neither Planned Delivery
Route...Studies of neonatal mortality lacked statistical power. Poor
data quality limited interpretation of studies on long-term neonatal
In other words, they simply do not know if there are any long term
implications to the health of the baby that relate to the type of
delivery the baby experienced.
Note that, though the NIH is based in the US, their state-of-science
reviews typically cover the world-wide literature on the topic at
The full document, which NIH ironically calls an 'abstract' (119 pages
of it!) can be viewed here:
If you search for the term [ long term ] in the document, you'll come
across only a few mentions that have to do with long term outcomes for
the infant, and none of them are conclusive, or even strongly
I trust this very recent, very comprehensive review of the literature
fully meets your needs.
