Ellen C. Hayes, MD

About

Read this page with one fact first: when the Aurora and Advocate physician directories were searched in August 2026, no profile for Ellen C. Hayes appeared at Aurora Fertility Services - West Allis, the clinic this page belongs to. Public listings place Dr. Hayes instead at Kindbody on North Broadway in Milwaukee and at an Ascension obstetrics and gynecology practice in the same city, with a Wauwatosa address also appearing in physician-directory coverage. Confirm the current practice location before booking, because this profile documents credentials rather than an active appointment slot at West Allis.

The credentials themselves are documented. An MD from Loyola University Chicago Stritch School of Medicine in 1997 led to obstetrics and gynecology residency at the Medical College of Wisconsin, then to a reproductive endocrinology and infertility fellowship at Emory University Medical Center in Atlanta, where research work during that training received the John D. Thompson Award in 2004. Board certification follows the same two-step pattern: Obstetrics & Gynecology, then the Reproductive Endocrinology & Infertility subspecialty, both through the American Board of Obstetrics & Gynecology, plus election as a Fellow of the American College of Obstetricians and Gynecologists.

Our dossier captures no Aurora patient-satisfaction record for this physician any more, because the profile that carried the practice listing is gone from the directory. That leaves third-party listings spanning 2012 to 2026 as the only external signal in our sources, and they are magazine and directory selections rather than clinical grading.

Clinical Expertise

• IVF: stimulation, monitoring, retrieval and transfer for patients whose path runs through assisted reproduction
• Diminished ovarian reserve: ovarian response assessment and protocol planning for patients with reduced reserve or a poor response to stimulation
• Recurrent pregnancy loss: systematic evaluation after repeated miscarriage, run as a diagnostic sequence rather than one more attempt
• Fertility preservation: egg freezing for planned delay of parenthood, and preservation before a treatment that threatens fertility
• LGBTQ+ family building: assisted reproduction for LGBTQ+ patients and couples building a family
• Clinical documentation available for this profile covers specialty scope and training, not procedural technique, so ask about specific surgical or lab roles directly

Why Choose Dr. Ellen C. Hayes

Awarded research inside fellowship training. The John D. Thompson Award at Emory, recorded for 2004, is the one research distinction in this record - a subspecialty fellowship that produced published recognition, not only clinical exposure.

A focus on the hard-to-answer cases. Diminished ovarian reserve and recurrent pregnancy loss are the two areas where patients most often want a physician willing to talk about probability rather than possibility, and both appear in this profile’s listed specialties.

Recognition repeated over more than a decade. Milwaukee Magazine listings for 2012, 2020, 2022, 2023 and 2025, plus a Castle Connolly listing from 2021 and an MKE Lifestyle listing from 2022, are third-party selections - magazine and directory choices, not clinical grading - but a pattern repeated across that span reflects standing in the local referral market.

A known availability constraint. The Aurora directory no longer lists this physician at West Allis, which means the practical question is not whether to consider this profile but where an appointment would actually take place. Patients choosing a doctor at this specific clinic should plan around Dr. Shanti as the West Allis-listed physician and treat this page as background on the practice’s history.

Suitable For
