    Zhang Heng and Zheng Shuang chose this place, so it should be good.

    My partner and I cannot express how grateful we are for Dr. Kumar's exceptional care and support. He took time to understand our unique situation and explained all our options, risks, and potential outcomes clearly. His ability to put us at ease and provide reassurance transformed our fertility journey. The staff were always friendly, helpful, and sensitive to our needs. Thanks to his expertise, I delivered the child we had long awaited, and we are deeply grateful for his care.

    I am extremely grateful to Western Fertility Institute for caring for me at every step of IVF. After disappointing experiences with local fertility clinics, I chose them. From our first meeting with Dr. Kumar, we knew we were receiving excellent care at a completely different level. Because I traveled from Canada, the clinic was very flexible and even helped with my medication needs. Our physician assistant, Lena, was always just an email away. We highly recommend them. Thanks to WFI, we are fortunate to have a healthy baby girl!

    Dr. Kumar is the best! He cared deeply about us, and I genuinely looked forward to appointments just to see him and his lovely staff. Everyone in the office was friendly and welcoming. We are so grateful for our success, all thanks to the outstanding WFI team!

    Unfortunately, I had a truly terrible experience. My transfer at this clinic was physically traumatic and caused bleeding because the procedure was careless and rough, making implantation less likely. The room looked like something from the developing world, and the so-called medical assistant was cruel, rude, rough, indifferent, and disrespectful, making the process even more painful. I later checked the laboratory and found it was not accredited, despite the clinic's heavy promotion. When the transfer failed, they requested about $7,000 for another transfer without telling me when it would begin. I also paid over $45,000 for 12 donor eggs but received only two alleged embryos. Someone needs to alert authorities to the fraud occurring at this clinic.

    I am so grateful to Dr. Kumar and everyone at WFI for helping us grow our family! WFI was my second opinion while dealing with secondary infertility, and after the initial consultation it was easy to decide to stay with WFI. Dr. Kumar proposed an action plan and a reasonable timeline; my nurse Jessica was always supportive and patient with my questions and concerns. My IVF journey was successful and relatively short thanks to this excellent team!

    We highly recommend this office! Dr. Kumar and Jessica, our nurse, were outstanding and went above and beyond to provide personalized, thoughtful care throughout the process. Even the office staff were friendly, professional, and never missed anything. It felt wonderful to work with a center that truly cares about its services and patients. We are so glad we ultimately came to Western Fertility Institute and highly recommend them. We had a terrible experience at another clinic near Encino: poor service, no attention to detail, and incompetent office staff who constantly apologized while continuing to make mistakes. It was extremely stressful, especially because this was our first time going through the process and we needed their support. Finding Western Fertility Institute was the best change we ever made, and my wife and I are so grateful we did! The difference was night and day, and we had peace of mind going through the process with an excellent team that cared about its patients.

    Thank you to Dr. Kumar, Quiana, and the entire team at Western Fertility Institute. IVF has many ups and downs and is emotionally difficult, but they reassured us throughout the journey and were very accommodating of our busy work schedules. We are now delighted to be expecting our first child and deeply grateful that we can have a family.
    Nov 27, 2024
    Dr. Kumar is the best, as are his clinical and administrative staff. We like being in control of our lives, and infertility takes that away. Dr. Kumar provided the perfect balance of information, compassion, and guidance. He made recommendations, offered perspective, and answered questions without making us feel rushed or like a number. His staff are also wonderful. I was impressed that they remembered who we were from one appointment to the next. They truly made the process feel personal. IVF obviously cannot guarantee a positive result, but even during our challenging moments, the staff and Dr. Kumar patiently answered our questions and showed compassion. I would absolutely recommend this clinic to anyone facing difficulties on their path to parenthood.

    Taiwanese + British combination was successful, thank you.
    Jun 13, 2025
    What a wonderful practice! Thanks to them, I was able to experience the joy of pregnancy. They know how to make you feel like more than a number and give your individual journey personal attention. Even after hours, the nursing team promptly responds to any questions!

    A wonderful team that always made me feel welcome.

    I just want to thank Western Fertility Institute. From beginning to end, everyone was wonderful and very understanding toward my husband and me. We are deeply grateful to the team for helping us through this journey. We cannot wait to bring our baby girl to meet Dr. Kumar, nurse Jessica, and the entire team. We already miss you.

    Before the embryo transfer, I felt extremely uncomfortable and even cried. Despite drinking so much water, my bladder was not completely full. He said, ‘I guess you cannot follow the rules.’ I had pushed myself, and I felt my own experience had been ruined. I was excited to help another mother have a child, but he completely took away my smile in one visit. If I could give no stars, I would. I did my best, but my own friend had to comfort and calm me before they returned to begin the transfer.

    Dr. Kumar is a knowledgeable and caring OB-GYN. All the staff here are excellent and attend to all your needs. Highly recommended!

    I had just turned 41 when I came to Western Fertility Institute and met Dr. Kumar, after several failed IVF attempts elsewhere. I was discouraged and felt I had lost all hope. Dr. Kumar did not sugarcoat my situation or make unrealistic promises. He clearly explained the treatment plan and immediately started medication to prepare me for the next retrieval cycle. For the first time in a long while, I felt hopeful again. After three egg retrievals and one embryo transfer, I am now holding my three-week-old baby. Our nurse Jessica was incredible. She stayed with us throughout, patiently answered every question, and made us feel deeply cared for. Everyone at Western Fertility Institute felt like family. Graduation day was emotional because I knew how much I would miss them. At 42, Western Fertility Institute helped fulfill my deepest wish, and I cannot wait to return when we are ready for a second child. Thank you to Dr. Kumar and the outstanding team at Western Fertility Institute for giving us this miracle.

    My experience at Western Fertility was wonderful. Before coming here, I went to a much larger clinic where I often felt like just a number. Since transferring to Western Fertility, everything has been completely different. I feel genuinely cared for as a person, not merely as a patient. Lens is an excellent nurse: knowledgeable, compassionate, and always supportive. Dr. Kumar also took plenty of time to understand my situation and made me feel reassured and cared for at every step. I am very grateful to share that, with Western Fertility's help, we now have a beautiful daughter.

    At this time last year, having a child was still a distant dream. Our journey to Western Fertility Institute began with a difficult reality and several devastating diagnoses. We immediately understood that building our family would require specialized medical care, so we chose a clinic carefully. We visited fertility clinics across the country—we live in Alabama—including clinics in Alabama, Georgia, Minnesota, California, and elsewhere. No doctor impressed us like Dr. Kumar. From our first consultation, Dr. Kumar was calm, direct, and confident. He clearly explained our options, detailed what would be required to achieve pregnancy, and developed a practical plan. What set him apart was not only his expertise but his conviction. When I told him how much this meant to us, he said, “It is not a question of whether I can get you pregnant, but when. I do not accept failure.” After the call, I looked at my husband and said, “He is the one. This is the clinic.” We immediately decided to work with this team, even if it meant traveling across the country. IVF is no small undertaking. The anxiety, fear, and emotional strain can be overwhelming, and you cannot anticipate how many questions you will suddenly have about your body. Western Fertility Institute stands out because of its communication. They clearly explained every step and set clear expectations. Everything felt transparent, with no concealment or confusion. I never felt like a number. I was a person. We both were. My emails were answered. Every question, even small or repeated ones, received a response. I was assigned a dedicated nurse and coordinator, Courtney, whose importance to this journey cannot be overstated. She answered questions, addressed concerns, calmed me when I was anxious, and skillfully brought Dr. Kumar into the discussion when I became overwhelmed. Communication was consistently thoughtful and caring. During a journey often filled with fear and anxiety, Western Fertility made us feel calm, secure, and supported. We initially had five good-quality, PGT-tested embryos. The first transfer failed. Dr. Kumar did not give up; he listened carefully to our concerns. He agreed to every possible test to help us find answers and gain peace of mind. That decision produced an unexpected diagnosis: adenomyosis, which had caused no symptoms and is easily missed. Dr. Kumar immediately adjusted the treatment plan, assured us we could still become pregnant, and guided us through several months of suppression with clarity and confidence. We trusted and followed the plan exactly. For the second transfer, I flew to California feeling nervous but hopeful. Five days later—earlier than I was supposed to test—I saw a faint line. Now that line is in my arms. Our daughter, Olivia Grace, entered the world healthy and perfect, everything we dreamed of. She is here because of the clinical skill, effective communication, and unwavering support of Dr. Kumar, Courtney, and the entire Western Fertility Institute team. Perhaps the best evidence of our experience is that only four days postpartum, I was already excitedly discussing our next embryo transfer with my husband. We know we will give every remaining embryo a chance. We know Dr. Kumar found the right protocol for us. We sincerely believe this team gives us the opportunity to bring more beloved children into the world. To anyone considering fertility treatment and unsure whom to trust: we would choose Western Fertility Institute again without hesitation. In fact, we already have. With gratitude, Jennifer and Dan

    I am incredibly grateful to Dr. Kumar. My first two pregnancies went smoothly, and I am about to deliver my third! Dr. Kumar is patient and kind and listens carefully to my concerns. The staff are also wonderful! Leslie is my favorite; she makes you feel at home and has a great sense of humor. We will always be grateful to Dr. Kumar and his team for making this beautiful dream come true! We would gladly return if we could!

    We had a wonderful experience at WFI, and I am now 26 weeks pregnant with a boy. From the beginning, Dr. Kumar explained our options in detail and recommended the approach with the highest chance of success. Because he honestly told us that intrauterine insemination (IUI) was unlikely to work for us, we went directly to in vitro fertilization (IVF). I believe this saved us considerable money and heartache, and we are very grateful for his honesty. Throughout the process, Jessica and the entire WFI team were thoughtful, communicative, and answered every question. Dr. Kumar is the best—he helped us become pregnant on our first attempt. We will always be grateful to him!

    A year ago, I was searching for what many readers may be seeking now: hope. After a series of disappointments, I longed for hope. Even walking down the street past smiling faces felt incredibly difficult. When another phone call reminded you that a gathering was “children only” and you were excluded, I longed for hope. During that difficult time, Western Fertility Institute and its exceptional team became a true beacon of hope. Their compassion, professionalism, and unwavering faith in science helped us through one of the hardest periods of our lives. To everyone still searching, hurting, and hoping: I sincerely hope you receive the same opportunity we did. If science can make your dream possible, the Western Fertility Institute team will do everything they can to help make it real. Wishing Western Fertility Institute continued success, and heartfelt thanks for everything you do for families like ours. 💙

    I had an excellent experience at WFI! The doctors and nurses were attentive, kind, and patient. Appointments started on time and were easy to schedule or change. I felt well cared for, and they always explained my condition in easy-to-understand terms with complete transparency and honesty. Highly recommended! Thank you!

    The best! We began IVF at a local clinic but quickly realized its chaotic atmosphere was not right for us. We consulted USC and Acacio Fertility, but ultimately trusted our instincts and chose Dr. Kumar and Western Fertility. They have been a blessing to our family! After one highly successful egg retrieval—something our local clinic somehow never achieved—two successful IVF cycles, and one successful reciprocal IVF cycle, I can confidently say we made the right choice. I have worked in women's health for 15 years and referred many friends and relatives to Western Fertility, all with successful outcomes. We have now seen 11 healthy, happy babies and children enter the world who would not be here without the excellent care of Dr. Kumar and his team.

    For several months, I worked closely with registered nurses Courtney and Caitlin. They were kind, responsive, and helpful, and it was a pleasure working with them. I had my embryo transfer today, and Dr. Kumar completed it before I could even ask whether he had started! He was very kind, and I felt nothing during the procedure. It was a wonderful experience. The nurses brought me a photo of the blastocyst and an ultrasound image of the transfer, memories I will always cherish. Dr. Kumar’s humor also created a relaxed atmosphere, which meant a great deal to me. The entire team was professional, compassionate, and reassuring. I am very grateful for their care and highly recommend them to anyone on the same journey. I had a wonderful experience and will continue working with them in the future.

    After trying for several years, my partner and I decided to pursue IVF, and Dr. Kumar was unquestionably the best person we could have found. Although the process was not always smooth, I never lost hope, largely because of Dr. Kumar’s steady guidance. He was always honest and kind and shared information at the right time. He helped me focus on the present instead of becoming overwhelmed by “what ifs” or what might happen in the future. This approach made an emotionally difficult journey feel manageable and supported. Our second IVF cycle was successful, and I am now 29 weeks pregnant. Transitioning to my obstetrician-gynecologist brought mixed emotions because it meant saying goodbye to Dr. Kumar and his exceptionally caring nursing team, who supported me throughout.

    我被转诊到西医生育中心,虽然我和丈夫最终没有选择他们(原因与此无关),但他们的入院指导(由Cailtin协助)以及与Kumar医生的会面都给了我们极大的支持。他们的沟通非常及时、有效、体贴周到。在这样的过程中,良好的后续跟进和检查是多么重要,我再怎么强调都不为过。非常感谢你们的关心和体贴。

    I followed Nurse Sofia's recommendation and traveled from London to see Dr. Quinn, and I am very glad I did. Although there were minor issues during treatment, Dr. Quinn's expertise, patience, and compassion helped me overcome every challenge. She always took time to listen, explain, and reassure me, which meant a great deal. Her nurse Sofia was also wonderful—supportive, caring, and always available when I needed help. Thanks to Dr. Quinn and Sofia, I achieved the result I dreamed of, and I am deeply grateful for their dedication and care.

    Caring, beautiful, clean, and friendly, with excellent customer service. I would recommend it to friends without hesitation.
    Mar 14, 2026
    Terrible. Before treatment began, I had 5 follicles. The doctor prescribed an extremely high medication dose, and after 8 days all 5 follicles had degenerated. At the first visit, I already had a 16.6 mm follicle, but he did nothing and did not perform another ultrasound to see whether it matured over the next few days. If you are over 40, do not waste your time and money here. This doctor is only at the clinic on Thursdays.

    This was an amazing experience, and everyone's support was incredible. Sarah was by my side throughout, as were many others, and they made the entire process so wonderful.

    Words cannot express how grateful I am to Dr. Kumar for giving me the most precious gift of my life—my baby girl. After multiple miscarriages and countless difficulties, he never gave up on us. He guided me through every step with patience, expertise, and compassion. Because of him, my family is complete. He is the finest doctor and one of the kindest people I have ever had the privilege of knowing. My heart is full of gratitude. May you always be blessed with peace and joy, Dr. Kumar.
    Mar 6, 2021
    I heard about Dr. Kumar through one of my mother's clients, whom he helped conceive twice. I did extensive research myself, and there is no doubt that he is the best, with a very high success rate. I cannot express how grateful I am to Dr. Kumar and his team, Rosie and Quiana, who were wonderful and patient with me. Thank you to this amazing team.

    The best place and doctors you can find in the United States. I have completed two amazing procedures, and I am grateful for everything I received and for how smoothly the process went. Highly recommended!!!
