> On the other hand, the mother doesn't have total control over whether she becomes pregnant or not.

The ONLY cases in which the mother has no control over whether she gets pregnant or not is in cases of rape or incest. Other than that, every woman can easily avoid pregnancy by not being sexually active. When women do become sexually active, they should know the potential consequences and pregnancy is one of them. Anyone who participates in consensual sex MUST take responsibility for whatever consequences come, and terminating their pregnancy is not a responsible way to deal with the consequences of sex.
