Yes......but the final say should always rest with the woman. Whether she is married or unmarried is irrelevant ...the father should always respect her final say and support her even if he disagrees....and if the pregnancy is the result of rape or incest it goes without saying that the father should have no say at all. There should be proper counselling and support so that the woman can be helped to make the best decision given her circumstances. All that said in most cases unwanted pregnancy could be avoided with proper sex education. We should be trying to stop unwanted pregnancies by promoting a proper sex education program at schools and colleges...the only ethical way to reduce or stop abortion.
