This happened to me in the USA. I told the doctor I want to be sterilized and neither my husband nor I wanted kids.
He told me it would be unethical. My husband might die and then my new husband would want children. I told him I would not change my mind, and such a man would be incompatible for marriage with me. He told me I’d change my mind. So basically, yes some hypothetical future man would want to use me for a baby factory, that’s why I can’t be sterilized.
I was 30. I’m older now, still don’t want them. I’m too ashamed to ask again for sterilization. My husband has a vasectomy scheduled soon (weird how a doctor had no problem doing that for him. Wonder what the difference is????)
I think the doctor thinks of your husband as a baby factory manager and as he wants the baby factory out of operation it is his choice. Now if he died a new manager could start up the factory again. I know this is extremely fucked up and there is no reason you should not be able to get sterilised but it is a fucked up world we live in.
When I got sterilized, the doctor asked me if I was in a committed relationship. Told him I was. Then he said that I need to treat this as permanent. Told him it wasn't a problem. He pushed a little more but inevitable told him that if things changed and I ended up with a woman who wanted children, adoption was an option. That ended it for me, and I was able to get the procedure done. I don't know if this is typical for men, but that was my experience.
I got a vasectomy when I was 31 and have never looked back. Would highly recommend it if you're committed to being child free. Was a simple discussion with my (male) GP and after a few questions to make sure I understood the implications and that I had thought it through he gave me the referral.
I really feel bad for women - they have so much more stigma and a harder time with this in general, even in progressive countries.
