oomis1105, the stigma is since most colleges have co-ed classes. SO in my typical real BY type class, not a single girl goes to college for that reason. Many pple that want to further their education either opt to take the Sara Schenirer course or Raizel Rite college courses, since these are done in frum, only female classes and I believe the professors are all female as well.
Some friends have taken accounting or other college courses online, for the same reason, to avoid sitting through endless co-ed classes and mingling with boys. These friends have gotten very recognized degrees landing them up with lucrative jobs.
I understand that you cannot become a dentist, surgeon or sonographist this way, but many pple are willing to give up those titles to avoid spending many years in college type enviroments.
