The couple were told about the IVF procedure by a friend.
Reciprocal effortless IVF is a combination of two IVF treatments that allows two women to take part in carrying their child at different stages. Ashleigh and Bliss stumbled upon the option when they were hunting for a way to have a child that was biologically connected to both of them, rather than pursuing the option usually utilized by lesbian couples of using a sperm donor.
But instead of placing the eggs and sperm into an incubator, they were placed inside the INVOcell device immediately after the eggs were retrieved. Once the eggs have been retrieved from the female, the sperm and egg are placed in a test tube for 5 minutes. During IUI, sperm is inserted directly into the uterus, with the goal of making it easier for a sperm cell to reach and fertilize an egg.
Embryos do not have livers, kidneys or lungs, with lab incubators normally used to remove toxins and perform other vital functions performed by the unformed organs.
"The way that Mr. Stetson came into this world was pretty special", Ashleigh, who gave birth to the baby, told CBS.
The Coulters are very happy with their new family, and find that their baby truly does carry a little bit of both of them.
Bliss explained that even though she never meant to carry her own baby, she said it was important for her to raise awareness for "the LGBT community as a whole, to let everybody know there are other options out there and different ways to start a family".
Ashleigh Coulter delivered baby Stetson in June. Only the second woman is actually pregnant.
The Coulters have already informed the media that they are receiving an "overwhelming amount...of questions from other prospective same-sex couples and they are glad they were able to help provide them with this opportunity".
Bliss Coulter and her wife Ashleigh were desperate to have a child, although Bliss did not want to carry a baby to full term.
After five days, the embryo was removed from Bliss and frozen.
But fertility doctors Kathy Doody and her husband Kevin offered the Coulters the chance to try out a revolutionary technique that would let Bliss act as a temporary incubator, before Ashleigh gave birth to him.
That's why it ended up costing them nearly 50% less than what it takes for a traditional IVF. It starts like traditional IVF.
This procedure is not much of a departure from regular IVF, according to Dr. Richard Paulson, a professor of obstetrics and gynecology and chief of the division of reproductive endocrinology and infertility at the University of Southern California.
The Coulters were tipped off about Dr. Cathy Doody.
Dr. Anna Jackson is a psychiatry resident at Vanderbilt University Medical Center and a member of the ABC News Medical Unit.
