    Dr. Hakan Cakmak received his medical degree from Istanbul University, Cerrahpasa School of Medicine, Turkey. He completed his residency in Obstetrics and Gynecology at Yale University. He subsequently received his fellowship training in Reproductive Endocrinology and Infertility at University of California, San Francisco. Dr. Cakmak is board certified in Obstetrics and Gynecology, and is a member of the American Society for Reproductive Medicine and Society of Reproductive Endocrinology and Infertility.

    Dr. Cakmak has special interest and clinical expertise in assisted reproduction, fertility preservation, endometriosis, pelvic pain and minimally invasive surgery including laparoscopic/hysteroscopic surgery. He has over 40 publications in leading scientific journals in the fields of infertility, assisted reproduction, fertility preservation, assessment of egg quality, endometriosis and implantation. His current research is focused on the investigation of the regulation of gene expression during egg and early embryo development, and the prevention of toxic effects of cancer treatments on the ovary.

    Dr. Cakmak is the recipient of multiple awards for clinical excellence and research including: the American Society for Reproductive Medicine Fertility Preservation Special Interest Group’s Prize Paper Award, Yale University John J. Meehan–Clifford R. Miller Award for academic excellence, Yale University “Resident of Excellence Award” for research, and the The Society of Laparoendoscopic Surgeons’ Outstanding Laparoendoscopic Resident Surgeon Award. In addition, his work on infertility has received two President’s Presenter Awards from the Society for Gynecologic Investigation.
