Fertility treatment

My name is Stephanie and I had a tubal ligation in 2015. In 2019, I got a divorce and I met a man who has no children and in 2020 I ended up having a ectopic pregnancy and having to have a salpingectomy to save my life. I regret getting a tubal ligation and I really want to give my man a baby boy to carry on his family name as he is the only son.
