The Division of Reproductive Endocrinology and Infertility (REI) offers a robust educational program for residents and fellows. The second year resident REI rotation is five-weeks, during which time the residents participate in the clinical services at Boston IVF, the principal clinical site of the REI Division of BIDMC, which includes consultations, ambulatory surgery, and advanced reproductive technology procedures. Residents are also responsible for REI patient activities that take place at BIDMC, including medical management of inpatients, gynecologic surgery, and in ambulatory patient care for the fellow-led Reproductive Endocrinology ambulatory clinic at the Beth Israel Deaconess Medical Center.

The academic program available to residents and fellows is robust, with residents encouraged to become involved in clinical and/or basic research projects that are conducted jointly with members of the division. Residents and fellows regularly attend national meetings, where they have the opportunity to present their research. The Division sponsors monthly conferences at BIDMC, in addition to monthly Boston IVF Grand Rounds, a lecture series held at Boston IVF featuring invited leaders in the field who speak on a variety of
reproductive endocrinology and infertility topics, as well as monthly Boston IVF journal club.

Clinical Care

The REI division includes eleven board-certified reproductive endocrinologists. The Division's full service clinical reproductive endocrine and infertility unit at Boston IVF delivers state-of-the-art fertility care. It is one of the largest assisted reproductive technology (ART) programs in the United States. Over the years, the faculty have
assisted in the birth of over 25,000 babies. Clinical services include ovulation induction, intrauterine insemination, in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), blastocyst culture and embryo freezing. Additional services include pre-implantation genetic diagnosis and screening (PGD), egg donation and gestational carrier programs, as well as fertility preservation (oocyte and sperm cryopreservation) for patients who desire to preserve their reproductive options. Surgical procedures performed include diagnostic and operative endoscopy (laparoscopy/hysteroscopy) for developmental and acquired abnormalities of the reproductive tract, procedures to correct developmental uterine anomalies, uterine fibroids and severe endometriosis.

In addition to the main facility in Waltham, Massachusetts, Boston IVF has sites in Boston, Quincy, Maine, Rhode Island and satellite clinics throughout New England.

Recognizing the impact that stress has on fertility, the Division offers complimentary care through the Domar Center, a Mind/Body medicine program that utilizes a treatment approach that is complementary to conventional medicine. The Mind/Body medicine program includes a wide range of specific mind/body techniques designed to elicit the relaxation response, as well as acupuncture, yoga and nutritional counseling. In addition, the Domar Center for Complementary Medicine offers a full range of mental health counseling services.
