If you have had your tubes tied and you decide you want another child?
can you get artificially inseminated with your BF's sperm and have healthy child?
The tube tying sterilizes you, not the man. It prevents eggs from entering the uterus. So it's not the sperm that's the problem, it's your lack of eggs.You need to have another surgery to reverse the tube tying. Although I'm not sure, it may be possible to use in vitro fertilization (they implant a fertilized egg). AI definitely won't work though.
Not a good idea
Yes you can. In Vitro Fertilization was designed for someone who has had tubal blockage for various reasons, but is otherwise healthy. Just remember it is not inexpensive, and the hormonal injections can make PMS look like good day.
