I need to know last year i had tubal ligation and i i want to have another baby is it possible.? if so how and does medical aid cover it?

It's possible: An operation which is called "tubal ligation reversal" is often possible. Insurance doesn't generally cover the procedure. I suggest having an exam at a medical clinic to determine whether or not this procedure may be appropriate for you. And if you receive medical aid please ask your social worker to check on any possible coverage for such a procedure.
