Patient Care Location



I am very pleased to be part of the Yale Fertility Center. I look forward to providing the best clinical experience for each of my patients while utilizing one of the most advanced reproductive facilities in the U.S. My approach is to provide the most compassionate and contemporary infertility services available to meet the individual needs and personal values of my patients. Areas of special clinical interest include optimizing age-related infertility, pre-implantation genetic diagnosis, male factor infertility, recurrent pregnancy loss, polycystic ovarian syndrome and fertility preservation. I am also the Program Director of the Yale REI Fellowship responsible for the mentoring, advanced training and organizing of post-graduate physicians who become board eligible in this sub-specialty after their 3 year experience at Yale.

My research includes the mechanisms of reproductive aging. This work has led to a simple blood test, antimullerian hormone (AMH), used worldwide today that helps determine the health of a woman’s ovaries, a rough estimate of her egg count and real time assessment of her biological clock.

I am currently co-editing two books entitled "Optimizing the Management of Fertility in Women Over 40" to be published by Cambridge University Press scheduled for publication in Fall of 2022 and "Polycystic Ovary Syndrome - Current & Emerging Concepts: An Individualized Approach to Management" which was published by Springer in May of 2022.

I also have had a research focus in population-based health outcomes research to gain better understanding of the trends of reproductive aging, health care disparities in IVF, vitamin D deficiency in reproductive health and a global improvement in the clinical practice of reproductive medicine. This has been achieved through collaborative studies and analysis of large clinical data sets from well characterized populations through the Assisted Reproductive Technologies Clinical Outcomes Reporting System (SART CORS), the Women's Interagency HIV Study (WIHS), the National Assisted Reproductive Technology Surveillance System (NASS) registries and the Reproductive Medicine Network (RMN).

I am a past-president of the Society for Assisted Reproductive Technology (SART), the primary, national organization that sets clinical and laboratory guidelines as well as the standards for safety and quality metrics for the practice of IVF in the US. As such, I am interested in using patient-physician advocacy to move toward expanding insurance coverage for infertility treatment for those who are without such benefits as well as moving toward strategies of closing the gap in disparities of access and outcomes in the utilization of IVF. I am also actively encouraging and mentoring young Yale faculty to bring their energy and insight to a national level within SART.

As Co-Editor-in- Chief of Reproductive Biology and Endocrinology (RB&E) I am actively involved in encouraging the publication of quality and novel research in the reproductive sciences.
