Well transhumanism could be considered somewhat of an ethos and generally wouldn't be all that supportive of "designer" breeding. And quite honestly, it's generally not all that easy or safe for a woman to have an abortion, so I really wouldn't worry about that. That's not to say that the ease of the process couldn't improve with technology, but this is something that the culture needs adapt to ahead of time; for example, our society needs to become more open to and knowledgeable about contraceptive measures. At the moment, however, if someone is really willing able to use abortion as they would any form of birth-control on a regular basis, maybe this type of person shouldn't be breeding anyway.
Also, consider pregnancies that are known to have some sort of disorder such as downs: The parents go ahead and "choose life," and they go through with the birth. Now they've got a child that can never amount to anything more than a fast-food employee, and who they will eventually leave in a home for the mentally disabled until they die the early death that's in-store for them. That's about the height of irresponsibility. What about rape? What about incest? Even something as simple as being completely incapable or unwilling to be a decent parent should qualify abortion. There's too many lives going nowhere, simply because of a lack of proper family planning. There are more adoptive children than the world can cope with already. Certainly there are exceptions, but why should a society bank on exceptions?
Certainly science should not be solely responsible for devising the answers to our problems. Most these choices need to be made on the individual level, but science must be able to facilitate these choices. For the larger problems, we need to be able to adapt our culture well enough to devise sustainable solutions, but again, science must be able to facilitate the decision-making process and the implementation of these solutions.

I am a bit curious what you guys mean by transhuman though. Like what humans will evolve into?
Transhumanism amounts firstly to self-enhancement. Large-scale human enhancement would generally stem from this individual enhancement. Eventually, this may have an evolutionary impact, but with humans, we can see a sort of personal evolution occur within a lifetime, and would say that transhumanism is primarily concerned with this.
