A Baylor University Medical Center surgeon has earned a spot on this year's TIME 100 list, the magazine's annual assessment of the most influential people in the world.

Dr. Giuliano Testa, Baylor's chief of abdominal transplantation, was honored for leading a team in the hospital's groundbreaking uterine transplant clinical trial.

The hospital was one of the first in the country to explore transplantation for women whose uteri don't function or were nonexistent.

In November 2017, a baby delivered at Baylor hospital was the first in the U.S. to be born to a mother with a transplanted uterus. That mother, who chose to remain anonymous, wrote about Testa for TIME.

The woman said she learned as a teenager she had been born without a uterus and was told she would never be able to carry her own child. Then, she wrote, she met Testa, and within a few months, she had a functioning transplanted uterus.

"The experience was not without setbacks. But through it all, Dr. Testa was a pillar of strength and assurance," she wrote. "And that confidence was contagious."

The patient said it was the honor of her life "to be a small part of his miracle."

Plans are underway for a second uterine transplant research study that will enroll 10 more patients, the hospital said in a news release.

"This is truly an incredible honor and a testament to the team and process we have in place at Baylor University Medical Center," Testa said in the news release. "I am proud our work is contributing to the body of knowledge on transplantation across the world and that we have been able to achieve our goal of helping women who have been previously unable to have a baby."

Testa was honored as a "titan" on the list, which included Amazon.com founder Jeff Bezos, NBA player Kevin Durant and SpaceX founder Elon Musk.

A second baby was born to a mother with a transplanted uterus in February. Testa said the baby girl's birth was "proof that this was not a clinical stunt."

"We want to make this a reality for all the women who have this kind of problem, and we believe even more that this is the right way forward," he told The Dallas Morning News at the time.
