You don't even have to have a partner to have "assisted reproduction" here. If you are a woman and you want a baby and can afford it you just go to a sperm bank and get knocked up. Is this article saying that you can't do that if you aren't married in France?
Well gay women can conceive. They just have to go to a sperm bank. Or suck it up and get drunk and have sex with some guy they meet in a bar or something.
