Iowa has also had a lot of trouble attracting doctors in general, but especially OBGYNs. This isn't just because of the abortion ban, of course, but it certainly doesn't help.
This is one issue which really needs to be addressed, and soon-hospitals are closing, especially in rural areas but also in poorer urban neighborhoods. Where I grew up the nearest hospital was 30-45 minutes away, and if that closed, the next nearest one was even farther away.
