About Us

Since 2003, the National Embryo Donation Center (NEDC) has been the country’s leading comprehensive non-profit embryo donation program.

Our Mission

Our mission is to protect the lives and dignity of human embryos. We do that by promoting, facilitating and educating about embryo donation and adoption (ED/EA). We’re also the only clinic-based organization that works with families of all races, faiths and ethnic backgrounds. Our office is in Knoxville, TN.

Our Vision

To share the love of Christ through the life-affirming process of embryo adoption while striving to place every donated embryo into a loving home. We will be a beacon in the darkness showing the love and respect due to these cryopreserved human embryos since they represent the very least of us. We look forward to the day when the responsible practice of reproductive medicine will render our services unnecessary.

What Led to the NEDC’s Formation

So why are we here? When couples go through in vitro fertilization (IVF), there are often remaining embryos.  Those are frozen and stored for later use. An estimated 1,000,000 human embryos are stored in the U.S. right now.

When couples decide that their family is complete but still have embryos remaining, there are a few options. They can donate the embryos to research or let them thaw, losing any potential for them to develop into children. Couples can keep them frozen. Or they can donate them to a couple who is unable to conceive. A lot of people share our belief that embryo donation is the life-honoring solution.

How We Live Out the Mission & Vision

The NEDC provides for all the medical, legal and social aspects of ED/EA. When someone donates embryos to us, we become the interim caregiver and our medical partners at Southeastern Fertility store them at no charge to donors.

From there, our team works hard to match the right embryos with the perfect family. You can choose from a huge number of available embryos with no waiting list! We also offer varying communication options between donating and receiving families. Those range from closed to a fully open relationship. Mediation is available for open relationships.

Thanks for visiting. We invite you to explore the website. Maybe the NEDC is the right choice for you!

    John Gordon, M.D.


    Dr. John David Gordon is an NEDC physician and co-director of Southeastern Fertility. He was born and raised in suburban Boston where he attended Milton Academy. He matriculated at Princeton University and graduated summa-cum-laude with a degree in Biology. Following Princeton he attended medical school at Duke University. Dr. Gordon was an intern in Obstetrics and Gynecology at the University of Texas Health Sciences Center in Houston. He then completed his residency training in Obstetrics and Gynecology at Stanford University Medical Center and his fellowship in Reproductive Endocrinology and Infertility at the University of California San Francisco. Dr. Gordon is board-certified in Obstetrics and Gynecology and subspecialty board certified in Reproductive Endocrinology and Infertility.

    From 1996-1999 Dr. Gordon was Associate Director at Long Island IVF. In 1999 he became the Co-Director at Dominion Fertility in Arlington, VA. Over the next 20 years Dr. Gordon was consistently voted as one of Washington’s Top Doctors in Washingtonian, Northern Virginia and Arlington magazines. While in Virginia, in addition to his busy clinical practice, Dr. Gordon served as the Division Director of the Division of Reproductive Endocrinology at Inova Fairfax Hospital and held the titles of Associate Clinical Professor of Obstetrics and Gynecology at VCU as well as Clinical Professor of Obstetrics and Gynecology at The George Washington University. Dr. Gordon is the author of many scientific articles and several books but he is best known to health professionals as the Editor-in-Chief of “Obstetrics, Gynecology, and Infertility,” a best-selling handbook with over 150,000 copies in print that is used worldwide by medical students, residents, physicians, and women’s health care providers. Dr. Gordon has been honored on numerous occasions for his educational activities and is a three-time recipient of the Council on Resident Education in Obstetrics and Gynecology (CREOG) National Resident Teaching Award.  Dr. Gordon is the coauthor of the patient friendly and informative book, “100 Questions and Answers About Infertility, 2nd Edition.”

    Dr. Gordon is committed to reducing the problem of the creation of too many embryos in IVF and he was very enthusiastic about the development of the Natural Cycle IVF (NC IVF) program at Dominion. In NC IVF the single egg produced each month is retrieved, fertilized and transferred. There are no extra embryos produced so the issue of abandoned embryos is avoided. While practicing in Virginia Dr. Gordon was very supportive of embryo adoption in general and the work of the NEDC in particular. After prayerful consideration, Dr. Gordon made the decision to leave his practice of 20 years in order to follow God’s call and relocate his family to Knoxville in order to work with Dr. Keenan and the NEDC.

History of NEDC

The first in vitro fertilization (IVF) or “test tube” baby, Louise Brown, was born in England in 1978 and the first IVF baby in the United States, Elizabeth Carr, was born in 1981. Since that time, the fertility industry has grown enormously and because of that, the number of remaining frozen embryos has significantly increased.

As laboratory technology and techniques improved, the ability to safely freeze and thaw embryos opened the possibilities for families to make additional attempts at becoming pregnant without having to repeat the egg retrieval process. It also allowed them to return for a sibling when they were ready to try again.

While no one truly knows when the first embryo donation occurred, they were usually performed in fertility clinics where the physician facilitated anonymous transfers between patients. In 1997, Nightlight Christian Adoptions expanded their services to include embryo adoption and began to educate the public regarding this option for infertile couples.

In the late 1990’s, the Christian Medical and Dental Association (CMDA) approached Dr. Jeffrey Keenan, a Knoxville, Tennessee, Reproductive Endocrinologist, with the idea of creating a medically-based non-profit embryo donation clinic. The clinic would accept all embryos regardless of number or grade and store them on-site. The clinic would also actively match willing recipients with donors and, then, conduct the actual transfers.

Originally part of the Baptist Health System in Knoxville, the new organization began assembling their grassroots staff and formulating the processes, parameters, and protocols needed to create the most beneficial program for both donors and recipients.

By 2003, the NEDC had received several sets of donated embryos from fertility clinics around the country and began to match them with hopeful families. In addition, they pursued and received federal grant funding to educate the public and create awareness of the embryo donation and adoption process.

By 2010, the NEDC had significantly increased their transfer/success rate, continued to receive grant funding, and moved to a permanent, independent location.

Since its inception, the NEDC has assisted in over 1,000 births and received over $3,900,000 in federal funding. It has become the premier center for ED/EA services and has been featured in multiple national media stories. The most important story, though, is the one that we can help write for you. We look forward to helping you complete your fertility journey.

While the NEDC is open to couples of all race, religion, creed, and background, our own Christian faith is the overriding principle upon which we operate.  As an organization guided by our religious faith and protected by the Constitution of the United States, the NEDC firmly believes in the sanctity of life beginning at conception and recognizes marriage as a sacred union between man and woman as defined by scriptures of the Holy Bible.
