Has anyone heard of the word adoption? If you absolutely want a specific gender, it's about the only guaranteed way to get it.
It's similiar as women who want an abortion and the fathers sometimes succeed at getting an injunction against it.
In the modern world, we forget that men also desire children. Some want to be fathers as badly as women want to be mothers.
There is something about the law in question that digs under my skin; reminds me a little too much of the days when husbands controlled everything about their wives. I doubt men need the premission of their wives to have vas. done.
Yet, it is meant as a means to get these husbands involved in the process. They do have a say in the decisio, as it will affect them and their dreams as well. As a woman, if you don't like that, then leave him or compromise.
I don't think there should be a law like this, no. But, it obviously brought up a huge issue in your friends' marriage. Makes me wonder how many husbands showed up during the surgeries, cursing at the doctors, yelling that they didn't want the surgeries done.
Just because a man can't give birth, that doesn't mean he isn't allowed to have an equal share in the decision-making process. Both sexes are required to make a child; both sexes get equal say.
In closing, yes, they should work it out on their own. Anyone 18 or older should be allowed to have elective surgery on their own accord.
If your friend forces her husband into signing, their marriage is over. If he forces her to have another child that she doesn't want, their marriage is over. So, they had better do some serious talking, compromising, and soul-searching, or they are going to head downhill fast.
