INVOcell is basically a form of IVF, but instead of the egg being fertilized in a lab, the egg and sperm are put in a small vial that's inserted into a woman's vagina, along with a diaphragm to ensure it stays in place, according to a 2012 study that outlines the procedure.
Ashleigh and Bliss said they feel blessed to be able to share this experience together and more children are in their future.
A same-sex Texas couple Ashleigh Coulter (left) and Bliss Coutler each carried their 5-month-old son Stetson, a case that doctors believe to be the first in medical history, according to reports.
It started with the stimulation of Bliss's ovaries and the egg harvest. In this case, Ashleigh was implanted with an egg contributed by Bliss and fertilised using donor sperm, with the other partner adopting the child.
"I think many have been excited about the thought but Kevin is correct, doctors in general, we don't like change so I think that their ability to share their story is phenomenal", Kathy said. "I think that was surprising to us but also exciting".More news: Nintendo Switch Surpasses GameCube, But …
While they came up with the idea during early conversations about starting their family, they weren't sure it was medically possible until a friend suggested they meet with Dr Kathy Doody, a fertility specialist in Bedford.
"Obviously, us being two women, we were like, 'How can we make this happen?'" Ashleigh said.
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. Then, the device was placed into Bliss' body for five days to start developing the embryo.
"It turns out, not surprisingly, that the woman's own body is a very good incubator", Kathy Doody told WFAA. "It's more accessible, it's more affordable and it's truly more natural".
The embryo was then removed and placed in Ashleigh's uterus. They got pregnant on the first try.More news: Mueller's Office Notifies FBI Of Alleged Scheme Involving Harassment Claim
"She got to carry him for five days and was a big part of the fertilization, and then I carried him for nine months", Ashleigh Coulter said. Doody had the idea to involve both mothers, which instantly appealed to the Coulters.
Ashleigh called Stetson 'our miracle baby, ' with Bliss branding him 'perfect...our little cowboy'. This was accomplished by a procedure called "Effortless Reciprocal In Vitro Fertilization" or Effortless Reciprocal IVF.
They said the process typically costs about half as much as traditional IVF.
Since Ashleigh's delivery, a second same-sex couple in North Texas chose reciprocal effortless IVF at CARE Fertility, got pregnant and delivered a healthy baby girl in September.More news: Mexico's president-elect to scrap $13bn airport project
