Update: We now have a beautiful daughter! 🩷 Our fertility journey was not easy. Before finding Fertility Center of San Antonio, we visited two other clinics in Texas, one in Dallas and one in Lubbock, and the difference in our experience was remarkable. From our first contact, the FCSA team made us feel supported and cared for. Their communication was always prompt and clear, which meant so much during such a heartbreaking time. The clinic is beautiful—modern, clean, and welcoming—and the doctors and nurses are highly skilled and exceptionally kind. They never made us feel like just another patient. They genuinely cared about our fertility journey and celebrated every step with us. We are thrilled to say that our first transfer at FCSA resulted in a successful pregnancy! This clinic gave us hope when we needed it most, and we are deeply grateful. If you are looking for a compassionate, responsive, and professional team to guide you through the process, I wholeheartedly recommend FCSA. ❤️

Amazing experience and excellent staff.

My husband and I began exploring IVF options with another provider in December 2023, but poor communication, vague information, unexpected billing issues, and multiple cancellations made the experience frustrating. We decided to try Fertility Center of San Antonio and wish we had contacted them sooner. From the moment we scheduled our consultation, the staff and Dr. Neal were incredibly supportive. They provided many details our previous clinic had failed to give us, making us better informed and more confident in our decisions. We are delighted to work with this clinic. *Update 02/06/25* Our due date is September 4! We are very excited and grateful to them 🖤

This clinic helped us build our family. The staff was discreet and kind, and the doctors were a pleasure to work with. The clinic felt like a cohesive unit, with everyone working together to keep your treatment on track. We are deeply grateful to Dr. Retzloff, Dr. Neal, and Dr. Adams for helping us have our baby boy and girl.

The doctors, front desk staff, phlebotomists, and nurses here are wonderful. They are all very friendly and informative and made our process so easy. I highly recommend them for IVF or infertility treatment.
Feb 25, 2025
This is all new and frightening to me, but everyone at the center has been wonderful, patient, informative, and kind so far. I am ready to begin my IVF journey with these excellent staff members and doctors.

I truly believe FCSA's reproductive medicine team is the best in Texas, if not the country. They are simply incredible. After one round of IVF, I had 6 healthy embryos, and my first transfer gave me my precious son, who is now 2.5 years old. When we moved away from Texas, we took our remaining 5 embryos with us. After unsuccessful treatment at several clinics in our new state, we now have only 2 embryos left. This speaks volumes about the extraordinary expertise and meticulous care I received at FCSA. If I have only one child in my lifetime, I have Dr. Neal and Dr. Retzloff to thank. I am in tears writing this because I sincerely hope they know how many lives they have touched. Thank you!!!

We would like to express our gratitude to Fertility Center of San Antonio for giving us a wonderful experience and helping us conceive a child to complete our family. From the beginning, they showed genuine care. Office staff Susie, Sylvia, and Evelyn were exceptionally attentive, and the nursing staff were professional and thoughtful. Dr. Adams and Dr. Relzloff were also wonderful. They created a comfortable environment that made the challenging process of trying to conceive easier. We ultimately became pregnant and are now at 13 weeks. God led us to Fertility Center of San Antonio, and we remain grateful for everything they did to help make our dream a reality.

Alyssa, Roz, Susie, Evelyn, and Sylvia provide excellent reception service. They are very attentive and kind.

Communication was very smooth. We consulted with the entire team, including Dr. Neil, nurse Irene, and Sylvia regarding finances. The whole process was organized and focused. Thank you.

I was not the one asking about IVF; I went in with my daughter because she was nervous. As soon as we entered, a woman greeted us with a warm smile. I believe her name was Alyssa. When we asked about an appointment, she directed us to Susie and again smiled and kindly asked, ‘How may I help you?’ My daughter had many questions, and Susie was very patient and answered all of them. If she was unsure, she asked Evelyn, who would also come over to answer. I know this will be a very expensive journey, but Sylvia explained several options that could help us manage it. I am very grateful that everyone was so kind to us. I believe my daughter will feel comfortable, and perhaps the decisions will be easier. Thank you for having such a wonderful team.

Words cannot express how grateful we are to Susie. My husband and I came here to learn about the IVF process, and Susie was truly wonderful. She answered all my questions, including some I had not thought to ask. This is a major decision for my husband and me, and with Susie’s help, I feel confident and well informed about the process and the next steps.

My husband and I had the best experience at Fertility Center of San Antonio! after both going through infertility issues and learning we’d have to go through the IVF process, I 100% felt like I was in the best hands at this facility. The doctors, nursing staff and front desk staff were all amazing, so kind and comforting, and helped us feel at home when going through one of the scariest journeys we’ve ever been through. I am happy to say that our first round of IVF was successful and we are expecting our first little bundle of joy in April! All thanks to God and everyone at FCSA!

Alyssa is amazing. She always greets me with a smile when I check in. She is the best!

Today was our second visit in our journey and the entire staff has been wonderful. I want to give a special shoutout to Alyssa who greets us with the brightest smile every time and makes sure the atmosphere is nice, calm and relaxing at the start of every visit.

This is by far the best clinic I have ever seen. I cannot say enough good things about the Fertility Center of San Antonio and its outstanding team. IVF is one of the most emotional and challenging journeys anyone can experience, but the care, compassion, and professionalism of everyone here made an enormous difference for us. From day one, we felt genuinely supported and cared for—not just as patients, but as people. They treated us like family. Every staff member we met went above and beyond to make the experience as smooth and hopeful as possible. Heartfelt thanks to Mariela, Monica, Irene, Sandra, Diana, Alyssa, Roselyn, Evelyn, Susie, Sylvia, and Ashley—your kindness, encouragement, and patience meant so much to us. You made every appointment feel welcoming, and your positive attitude helped us through the hardest moments. Thank you to the entire lab team for your hard work behind the scenes. We know how important your role is and are deeply grateful. And of course, thank you to two exceptional physicians, Dr. Neal and Dr. Retzloff, for your expertise, guidance, and genuine care. Your confidence and compassion gave us hope when we needed it most. Thanks to this amazing team, we successfully completed our IVF cycle—none of it would have been possible without each of you. We will always be grateful for your support, professionalism, and care throughout the process. We look forward to seeing you again in the future 🥰

Dec 15, 2025
Give the clinic 5 stars because overall I think they care about their patients. IVF was physically, emotionally, and financially exhausting, but I would probably do it all again if our chances were better. IVF did not go as we hoped. We only made 1 embryo and sadly that baby did not survive. The only aspect of the clinic that I would give 1 star is the after care. When they called me to tell me the heartbreaking negative results of the pregnancy test over the phone I was obviously devastated. No follow-up was offered. No support or resources were offered. I was genuinely surprised that a fertility clinic of this size doesn’t offer grief support recourses such as support groups in the community or a list of recommended counselors. 9 months later and the grief still comes in waves. If that embryo had survived, its due date would’ve been last week.

Susie is wonderful! I appreciate how carefully and thoughtfully she scheduled my appointment.
Dec 5, 2025
Many thanks to San Antonio Fertility Center. Everyone, from the nurses to the doctors, was wonderful, especially Susie. Thank you for making my wife and me feel comfortable as we begin this journey. All the women at the front desk are excellent. See you at our next appointment!

I would like to take this opportunity to thank the entire staff at Fertility Center of San Antonio for making my wife’s and my dream come true. Our treatment began last March, and now we have a beautiful daughter.
Dec 30, 2025
The staff are amazing! Everyone is very kind, compassionate, and helpful. Thank you for making our journey so easy and pleasant.

Mariella Segura is another ignorant person in healthcare who does not understand that the delivery fee goes to the company, not the driver. Please do better next time and show some appreciation to the people providing you a service because you could not be bothered to do it yourself.
Nov 6, 2025
From your first phone call through every appointment, you feel extraordinary warmth and care. From Susie at reception 🫶🏼 to the checkout staff, doctors, and nurses, their thoughtfulness is unmatched. Everyone at Fertility Center of San Antonio goes above and beyond to make you feel cared for and supported. To every woman and couple facing fertility challenges: remember that you are not alone. This team will accompany you throughout and help you through difficult moments. I highly recommend Fertility Center of San Antonio.

Excellent care team, including Dr. Neal, nurse Chris, and Ms. Sylvia. Highly recommended!

Choosing the right IVF clinic is a crucial decision, and we are so glad we chose Dr. Retzloff and Dr. Neal. We evaluated about five clinics before deciding, and they stood out for their clear, honest information—including an open discussion of the pros and cons—which gave us confidence about treatment. They genuinely care about every patient and never treat you like a number. Over time, we developed a wonderful relationship with them, and their guidance and support meant so much to us. Special thanks to Monika, Sandra, Ms. Sylvia, Evelyn, Irene, and the entire staff for their attentive help throughout treatment. Today was our “graduation day,” and we are incredibly grateful. We highly recommend this clinic to anyone seeking compassionate, professional care in San Antonio.

I love this clinic! Everything is extremely clean! I would definitely recommend it. Sally, Alyssa, Evelyn, and Sylvia are all wonderful—professional, kind, and helpful! 😇
Mar 31, 2026
We wish we had come here sooner. Dr. Neal and Dr. Reitzloff are truly wonderful. We felt comfortable and were never dismissed or treated like just a number. They worked with us to develop a treatment plan and offered their recommendations. The clinic staff were also excellent and greeted us by name as soon as we entered. The nurses, the phlebotomist, and even the ultrasound technician were all wonderful. We never imagined we would reach this point. After our September 25 transfer, we had a positive pregnancy test, and we will soon welcome our baby boy, due in June. If we decide to have another child, we will definitely return. I will continue recommending this fertility center to anyone considering IVF.

Alyssa and Sally are amazing! I was nervous beforehand, but I felt much better after speaking with them. ❤️❤️

Unfortunately, my first IVF procedure ended in an ectopic pregnancy, and Dr. Retzloff was one of the doctors who assisted Dr. Neel with my surgery. He was very kind and answered all my questions. He is one of the best doctors.

Dr. Retzloff and Dr. Neal helped us achieve our dream. Words cannot express how precious that is. Highly recommended.

Dr. Retzloff and the entire Fertility Center team in San Antonio are wonderful! I thank them for giving us two miracle babies during our reproductive endocrinology care from 2016–2020! He, Dr. Neal, Dr. Martin, Dr. Adams, and the talented nurses and staff never gave up on us despite our difficult diagnosis of dual-factor infertility. Our difficult case probably lowered their overall SART rating and required multiple IUI and IVF cycles before we finally succeeded. He and the team are knowledgeable and compassionate! Dr. Retzloff always answered every question, even when I brought 4 pages of questions or submitted them through the portal. If I wanted to try something new, he would adjust my treatment and educate me about whether a treatment, supplement, or random silly 'why not try this' idea I brought him might or might not help my DOR and my husband's male-factor infertility. Because of him and their expert team, I can hold my children today and share our success story on infertility podcasts and in support groups. I will always be grateful to him and the team. Thank you, Dr. Retzloff and FCSA!

Dr. Retzloff is incredible—a compassionate, knowledgeable, and highly skilled physician. I had a wonderful experience with him and his entire staff. Highly recommended.
Jun 9, 2024
Dr. Retzloff and his team are wonderful! I used to think I could not have children, and now I have three healthy, adorable children. Fertility treatment can be very stressful, but Dr. Retzloff and his team were extremely helpful and attentive throughout treatment. I love this team!
