This has some pluses and minuses.
Of course, I support any endeavour to improve the well-being of the unborn child (as well as newborns). And I do believe such a society will help promote the idea that a fetus is a human being. After all-- you don't treat a woman's body part as a patient.
On the other hand, fetal-maternal medicine units are often the ones that perform late-term abortions after the discovery of malformations, diseases and chromosomal abnormalities. Will they produce more prenatal tests, and therefore, more reason to have abortions?
Will they save more babies than they kill?
I hope so. Probably so in the long term, if only because the fetus is treated as a patient, and that bolsters the idea that the unborn child is a human being.
