(Minnie, I added you to provide support for your points using the links to medical procedures below)
The woman's absolute right to choose comes from HER absolute right to control over her own body. Thus,
not only is the choice to abort within her control, but also whether or not to have sex and under what conditions she will allow it. The following support a man's right to avoid the responsibility of HER choice.
First, as has been stated by other members, not all sex leads to pregnancy. That's because a woman is not always "ripe" for pregancy. A woman is well-aware of her monthly cycle and can pretty much avoid sex when she is at greatest risk of unwanted pregnancy. Remember, the woman is in control of whether to have sex or not.
Second, (in voluntary sexual activity) the woman can always refuse to have sex unless the male conforms to her requirements. She decides if she wants to take contraceptives and/or if he must wear one himself before she will engage in the activity. Again, the woman is in control of whether to have sex or not.
Third, in the event she does get pregnant she has the absolute right to decide whether to abort or not. This we all already know, whether we agree with abortion or not. It does not matter if the male wants to be a father or not, is willing to marry her or not; SHE has the final decision. Thus SHE gets to decide what happens to ALL parties (man, woman, and child)
for the rest of their lives!
Under our current system if a woman decides to have the baby the male is then obligated to financially support the child until it's 18th birthday. This also often carries with it the social onus of parental responsibility, i.e. both society at large as well as his unwanted family (woman and child) expect some emotional support; holding the father accountable if he is unwilling to provide it.
There is intense social pressure to marry, or at least "take responsibility" as we see repeated in this thread over and over. This leads to anger, resentment, hatred of this unwanted burden. Such emotions then lead to domestic abuse, child abuse, alcoholism or drug abuse, etc., etc., etc. none of which is good for anyone caught in this situation, least of all the unwanted child.
So not only are the initial consequences NOT clear, but people seem perfectly willing to ignore the very real consequences we see repeatedly when a couple is forced to deal with an unwanted child because of a unilateral decision made by the woman. Remember, it is only the WOMAN who has the absolute right to choose.
Finally, I would like to point out that
during the first nine weeks of the pregnancy there are non-surgical MEDICAL methods of aborting the developing fetus. That means there is time to inform the male, find out how he feels about things, and if he does NOT wish "marriage and family" the female can assess the situation and simply take some medicine to induce the abortion. No invasive surgery required.

Men should have the option of "opting-out" of responsibility for the woman's absolute choice.
