HOUSTON -- One recent day at Dr. Natalie Carroll's OB-GYN practice, located inside a low-income apartment complex tucked between a gas station and a freeway, 12 pregnant black women come for consultations. Some bring their children or their mothers. Only one brings a husband.

Things move slowly here. Women sit shoulder-to-shoulder in the narrow waiting room, sometimes for more than an hour. Carroll does not rush her mothers in and out. She wants her babies born as healthy as possible, so Carroll spends time talking to the mothers about how they should care for themselves, what she expects them to do -- and why they need to get married.

Seventy-two percent of black babies are born to unmarried mothers today, according to government statistics. This number is inseparable from the work of Carroll, an obstetrician who has dedicated her 40-year career to helping black women.
