CMV: Men should also have a say when it is about their children being aborted or not.

First: I don't particulary mean that they can force a woman to carry to term or for an abortion.

A woman has all the power when it is about childbearing and conceiving. There are probably countless men in the world who got "tricked" by their partners into long term commitment or just locked as a source of income by woman who lied about their birth control or got pregnant in some other way.

Thus it would be just reasonable to allow men, to give their opinion about the child. Of course the woman can not be forced to perform an abortion or to carry to term. But the man should be able to get free from every engagement if he doesn't want to be the father. This should be tied to the same rules as the mothers decision to keep a baby or not. After the first trimester you are out of luck and are locked.
Maybe a woman would be even willing to carry to term, when she get rid of the responsibility for the child when the father wants to take care after birth.

This might be still open to abuse, since someone could know to be pregnant and just not tell, but it would be an improvement imho.

Edit: my view changed a lot when getting comments, thanks everyone.

I think some form of legislation is still necessary to make the system less prone to abuse. I really don't know a suitable solution. Easy way would be to offer sperm-banking at some non-profit and cheap vasectomies for everyone to be affordable. But I guess some people would have some problem with that too.

Edit: This is also applicable for every situation where one party is tricked into pregnancy by the other one. Also to "fix" a relationship or what other obscure reasons there are. Usually men are without options then. Thus why this was focused on men in the beginning.

It sounds like you're not really in favor of men having input on abortions themselves, as you say that a woman should not be forced to carry to term if she does not want to.  It's really hard to say men have any inpit on the matter when the final decision still falls to the mother.

What it sounds like instead is what some mens-rights types call "financial abortion" where the father absolves himself of any and all responsibility for a child he does not want.  The problem with that, is that child support and related systems don't exist to benefit the mother or to teach the father a lesson, they exist because, following birth, there is a being that is unambiguously a living person with great material needs.  In short, child support is for the child.
