It's uncontroversial that women should not be forced to have abortions against their will. For one thing, this follows from a general right of veto against invasive medical procedures. But we may also think there is a second reason, namely that it would be a great harm to a prospective mother to kill her cherished "unborn child" (her "baby", as she thinks of it), and all her plans for their future together -- plans which may have taken on a central role in her life story and 'identity' as she conceives of it.
This second reason would also seem to apply to the prospective father, though perhaps in a slightly muted fashion. The father is not so intimately acquainted with his "unborn child" -- though if he has felt its kicks through its mothers belly, seen ultrasound images of its little fingers and toes, or even simply observed the growing bulge over the weeks and months of pregnancy, such experiences might conceivably nourish the initial blossoming of paternal love and attachment. I'm unsure how significant an effect this is likely to have, though. Perhaps the greater impact, for the father, is at the level of abstract knowledge: that there exists a particular little human organism that, if properly nourished and protected, will grow into his future son or daughter. It is easy to understand a prospective father investing a great deal of meaning and significance in this fact, and thus feeling harmed - even violated - if he is unable to protect his unborn child--if others terminate it against his will.
Does this then also justify granting a paternal right of veto against abortion? It is some reason in favour, at least, but it may be outweighed by considerations of the unhappy mother's bodily autonomy. What do you think?
