Dr. Bat-Sheva Lerner Maslow

Dr. Bat-Sheva Lerner Maslow, MD, MSCTR, FACOG

Reproductive Endocrinologist

Dr. Bat-Sheva Lerner Maslow is an accomplished reproductive endocrinology and infertility specialist. Dr. Maslow graduated magna cum laude from Barnard College with a bachelor’s degree in history before attending the Albert Einstein College of Medicine, where she earned a medical degree with distinction in reproductive endocrinology. After medical school, Dr. Maslow completed residency training in obstetrics and gynecology at the University of Pennsylvania and subspecialty training in reproductive endocrinology and infertility at the University of Connecticut. Additionally, she completed a master’s program in clinical and translational research at the University of Connecticut, focusing on both medical research and the communication and application of scientific findings.

Prior to joining our team, Dr. Maslow was an associate physician at a top-ranked private infertility practice, Gold Coast IVF, in Long Island. There she treated women and couples with a wide range of medical and surgical issues. Dr. Maslow’s research on fertility preservation, age-related infertility, genetics, and other issues in fertility and women’s health has been published in Obstetrics & Gynecology, Fertility & Sterility, the Journal of Assisted Reproduction and Genetics, and other nationally recognized medical journals. Additionally, Dr. Maslow writes and lectures on topics related to the intersection of Jewish law and reproduction. She serves as the Director of medical education for Nishmat’s North American Yoatzot Halacha Fellowship Program, which trains female scholars to address questions in Jewish law related to women’s health.

Dr. Maslow’s professional and academic choices reflect her strong belief that knowledge is power, especially when it comes to women’s health. Many highly educated women go through life without ever understanding the basic nature of their fertility. Dr. Maslow views this as a great injustice. It is her personal mission to take steps toward empowering women through education, clear and contextual information, and accessible, affordable healthcare.
