For over 20 years, as the founder and medical director of the Fertility Center of Dallas, Dr. Putman and his dedicated team of professionals at the state-of-the-art in-vitro fertilization facility utilize the latest technology and scientific advancements to address infertility issues.

His in-vitro fertilization success rates are, and continue to be, among the highest in the nation. National and international patients travel to Fertility Center of Dallas to be evaluated, tested, and successfully treated by Dr. Putman and his associates. A frequent lecturer, he is considered an expert media resource. He teaches resident physicians and produces teaching videos, and has authored numerous journal articles. He is a Clinical Associate Professor in the Department of Obstetrics and Gynecology with Texas A&M Health Science Center College of Medicine, and University of Texas Southwestern Medical Center. He has medical appointments at Baylor University Medical Center Dallas, Baylor Surgicare, and Presbyterian Hospital, Plano. Dr. Putman has been named one of the Top Doctors in America and named a Super Doctor in Texas Monthly. He is a recipient of the Patient’s Choice Award, Living Magazine’s Best of Rockwall & Rowlett, Readers’ Choice 2016, and selected by his peers as Best Doctor in Dallas in D Magazine from 1999-2016.

Dr. Edward D. Tarnawa, a native Texan, graduated from Southern Methodist University and received his medical degree from the University of Texas Health Science Center at San Antonio, where he finished first in his class and was elected to the Alpha Omega Alpha national medical honor society. Dr. Tarnawa returned to Dallas for fellowship training in Reproductive Endocrinology and Infertility at the University of Texas Southwestern Medical Center following his residency in Obstetrics and Gynecology at the Medical University of South Carolina. A member of the American Society of Reproductive Medicine and American College of Obstetrics and Gynecology, Dr. Tarnawa’s professional interests include in-vitro fertilization, recurrent pregnancy loss, polycystic ovary syndrome, endometriosis, male factor infertility, preimplantation genetic diagnosis, fertility preservation, and minimally invasive gynecologic surgery.

Li (Lilly) Zhang, PhD, HCLD, ELD earned her doctorate degree in Reproductive Physiology from Louisiana State University. An expert in reproductive technologies and highly advanced reproductive systems, Dr. Zhang serves as both the certified high-complexity laboratory director and the certified embryology laboratory director. Her expertise includes in-vitro fertilization (IVF), embryo transfer (ET), intracytoplasmic sperm injection (ICSI), embryo biopsy for preimplantation genetic screening (PGS) or diagnosis (PGD), all aspects of andrology, and embryology, sperm, and embryo cryopreservation (freezing). She consistently helps the Fertility Center of Dallas in achieving impressive IVF success rates. She has published numerous articles and journal abstracts, and has developed an endometrial cell co-culture system to help embryo development in the IVF lab. Dr. Zhang is an active member of the American Board of Bioanalysis (ABB) and the American Society for Reproductive Medicine (ASRM). She is fluent in Chinese.

Equally matching the team’s scientific and medical talents are the warm, personal relationships they have with each patient. “We offer individualized treatments that are tailored to meet each patient’s specific needs,” Dr. Putman said. “We perform complete and thorough diagnostic testing and develop a personalized treatment plan for women and couples who are experiencing infertility issues.”

As women age, the number and quality of eggs decreases. “The sooner you find out you haven’t achieved a successful pregnancy, the better the chance that we can help you,” Dr. Putman explained. “We believe in an aggressive approach to discover why you haven’t gotten pregnant. Once identified, we can sit down together and strategize a plan that offers the best chance for success now, as well as for future pregnancies.”

In-Vitro Fertilization (IVF)

“IVF is the ultimate strategy for treating infertility,” Dr. Putman explained. Outside the human body, eggs are combined with sperm in the embryology laboratory and grow and develop under the exact same conditions found inside the body, until they are ready for placement or frozen for future pregnancies.

Age matters when you are considering pregnancy. A woman is born with all the eggs she will ever have–approximately one million. By puberty, her egg count has been reduced to 300,000, and by age 31, that count is 100,000. By age 38, only 35,000 eggs are left, and those remaining eggs continue to age with her. Past age 38, chances of achieving a successful pregnancy may involve higher levels of medical technology, as well as increased time and expense. “IVF can preserve future fertility by freezing eggs or embryos,” Dr. Putman said. Detection of inherited (sometimes fatal) genetic diseases can be accomplished through IVF, thus preventing passing on the abnormal genes. For the most successful outcomes, seek a fertility specialist as soon as you discover you are having difficulty getting pregnant or maintaining a pregnancy.
