For those of you out there who don't want to be parents ever/ever again, there is a non surgical female option. I recently talked to my doctor about tubal ligation (getting ones tubes tied) and he told me about Essure. It is a procedure where tiny coils are placed into the falopian tubes through the vagina and then the tubes scar around them preventing pregnancy.
I checked out the website and even though it is a very new procedure, the results sound really great. A lot of the stories involved women who ended up pregnant after their husband had a vasectomy. The men didn't go to their follow up exams to make sure the procedure was successful. A lot of people don't realize that men have to follow up and there is something like a three month period after the surgery that you have to use other forms of birth control.
Similarly, you have to use alternate birth control for a couple of months after this procedure to ensure that the scarring successfully blocks off the tubes before having unprotected sex. I know a lot of men get pressured to have a vasectomy because it is easier than tubal ligation. Now there is a procedure that's easier than both.
