HRC---where Dr. Potter works has a state to state list and you can call the individual clinics to see what services they may provide....not all will do the IVF/PDG just for gender selection but I know that some do in the southern states.....and some even use HRC to microsort...
This is the list of states with clinics----http://www.infertilityspecialist.com/fertility_clinic_directory.html
This is a North Carolina clinic-----they offer family balancing...which is the term Ive seen a LOT when they offer services to couples just seeking a specific gender.....

When I hear back on the specific link to the Alabama clinic I'll post it. Google "family balancing" and you will get quite a few hits for a selection of clinics.....some may not offer the extreme IVF/PDG/MS but most will offer the IVF/PDG.....or IUI/PDG....IVF/MS.....Just check under their services and most of the site list their fees as well.
