    About our process
    Jul 27, 2025
    Dr. Cakmak was incredibly caring and thorough. He took the time to explain everything he was doing during my embryo transfer and made sure my husband and I were well informed every step of the way. His attention to detail and clear communication really put us at ease - especially meaningful with this being our fifth embryo transfer. His calm and compassionate approach helped us feel both hopeful and excited about the experience.

    Dr. Cakmak is extremely patient and methodical in explaining terms. He has the gentleness and respect amongst his staff and also just prepared answers even with consults that most common questions have been answered.

    I was impressed with the detailed explanation all through the procedure about what would happen and was going on. The doctor made sure I understood and could follow along at each step.

    Dr. Cakmak was incredibly talented at being able to explain the medical side of things in a way I could easily understand. He was clear, he explained everything by writing it down for me (and gave me the notes to keep after), he was very prepared at having looked in-depth at my file before I arrived. He was very kind and courteous, especially for such tricky and emotional situations.

    The visit with Dr. Cakmak was good. Only reason some of these are a 3 is because he's not the most friendly and for something as personal as trying to conceive, could be nice to have someone who's a bit friendlier / more empathetic. But not a reflection of the content and care he provided

    Dr. Hakan Cakmak exemplifies the highest standards of excellence in patient care. His expertise and professionalism are evident in every interaction, and his ability to blend clinical precision with genuine warmth and kindness makes a profound difference in the patient experience.From the initial consultation through every step of the IVF process, Dr. Cakmak demonstrated a deep commitment to patient-centered care. He took the time to explain complex medical information clearly, answered all questions with patience, and provided unwavering support during what can be a challenging journey. His compassionate approach not only instilled confidence but also created a sense of trust and reassurance that was invaluable. He valued my thoughts and opinions throughout my treatment care, Integrating them Into his clinical decision making. I felt like a partner or colleague during my IVF cycle. UCSF is incredibly fortunate to have Dr. Cakmak as part of its team. His dedication, empathy, and outstanding clinical skills make him a truly exceptional provider.

    Wonderful team

    Dr. Cakmak is the only doctor I've ever worked with who knows all about PCOS and insulin resistance, as well as other issues surrounding these two unique problems. He is incredibly knowledgable and I always feel like I'm getting extremely crystal clear information about my issues when I speak with him. I wish more doctors would approach healthcare in the way that he does. He provides straightforward information that is factual with no room for "what if." I very much appreciate his honestly and clarity and the care he is providing me.

    My experience with UCSF has been positive in all interactions. The staff here has been amazing. I have used other facilities and UCSF far exceeds other experiences.

    Dr. Cakmak showed support during my last miscarraige and made sure I was informed and felt confident about this current FET attempt.

    Dr Cakmak makes me feel like I am in very capable hands in a situation where I have very little control, so that is really important.

    Dr Cakmak is exceptional. He did our transfer on a day that someone else had scheduled to do it just to ease our mind about the uncertainty and stress of this process. He is skilled, trustworthy, informed and thorough

    I feel so lucky to have Dr. Cakmak as my reproductive endocrinologist. He is so patient, warm, and never seems rushed during the visit. He makes sure to answer every question and provides excellent anticipatory guidance.
