BOSTON -- Fertility clinics have put a new twist on how to make babies: A "two-mom" approach that lets female same-sex couples share the biological role. One woman's eggs are mixed in a lab dish with donor sperm, then implanted in the other woman, who carries the pregnancy.
A New York doctor described 18 of these cases Tuesday at a fertility conference in Boston that featured other research on ways to help same-sex couples have children. Dr. Alan Copperman is medical director of Reproductive Medicine Associates, a New York City clinic that does the "two-mom" approach.
A New York couple — Sarah Marshall, 40, a recruiter for law firms, and Maggie Leigh Marshall, 35, a real estate broker — used it to have their daughter, Graham, now 18 months old. Maggie's eggs were used to make embryos that were implanted in Sarah, and both women are listed as parents on the birth certificate.
"It allowed us both to participate," Sarah Marshall said. "I had to mentally and psychologically give up the idea of, is she going to look like me or my family. But from the time I started carrying her up to now, she is definitely mine."
