Sorry, c-sections don't do anything to you hormonally - you really don't even get anywhere near the ovaries. Pregnancy and the postpartum hormonal changes though - that's another matter. Lots of women seem to experience libido problems after they start having kids. Could be the obvious - it's the KIDS. Could be hormonal - whatever hormonal shifts do to cause postpartum depression could also affect libido. Thyroid problems also often crop up in the time period and frequently go undiagnosed.
But sorry - you can cross the c-section off your list.
