Dr. Oktay’s professional life has been dedicated to the science of fertility preservation and infertility treatments.   As a clinician-scientist, he is a leading expert in fertility preservation, as well as in ovarian stimulation and in vitro fertilization.

Dr. Oktay conducted key research on ovarian follicle and embryo development, as well as on controlled ovarian stimulation and in vitro fertilization. Following his first description of the relationship between BRCA mutations and low ovarian reserve, his work led him to discover a key role for DNA repair efficiency in oocyte aging.

Dr. Oktay was invited to serve on the President’s Cancer Panel as an expert on fertility issues of cancer patients and fertility preservation. In attestation to his recognition as a leading clinician-scientist in infertility field, he has been continuously funded by the National Institutes of Health to study various aspects of ovarian biology and fertility preservation.
