Can you take birth control pills if you have your tubes tied?

Answer 1

No, there is no harm in doing so. Using Birth Control pills may be helpful in other conditions, such as endometriosis, polycystic ovarian syndrome, or certain bleeding disorders. Some women will also do so to control irregular or excessive bleeding during perimenopause. That may be true even if pregnancy prevention is not a concern.
Yes. But not for the sake of birth control. Having your 'tubes tied' does not effect hormone production. If you have a heavy or irregular period, you may benefit from taking the pill. Talk with your doctor. I guess the question for you would be - why do you want to take the pill if your tubes have been tied?
Yes, having your tubes tied only prevent ova from entering the uterus. Other biological functions will remain the same
Women who have a tubal ligation can use the birth control pill for other purposes.
