Research

Dr. Martin Keltz, M.D., has been involved in clinical research in reproductive medicine for over 30 years. The majority of his research has focused on the optimization of evidence-based fertility diagnostics, including sonohysterography, chlamydia antibody testing, and semen testing. More recently, his research focus has been on outcomes-based assessments of assisted reproduction
protocols and techniques, as well as reproductive surgery. His areas of investigation have included IUI preparations, stimulation protocols in IVF, preimplantation genetic screening, laparoscopic procedures for pelvic pain, endometriosis, and infertility, and most recently, a focus on a variety of hysteroscopic procedures and their impact on live birth rates following spontaneous or IVF conceptions. Dr. Keltz is the first or senior author and principal investigator on about eighty percent of his publications.
