Expanding the Prelude Network to 4th Largest IVF Market in the U.S.


Acquisition Adds Presence in a Top Metropolitan Area to the

Fastest Growing Network of Fertility Centers in the U.S.


NEW YORK (March 6, 2018)—Today, Prelude Fertility announced the addition of Advanced Fertility Center of Chicago, S.C. (AFC) to its rapidly growing network of fertility centers, now with 31 locations, following partnerships developed last year with Pacific Fertility Center and Vivere Health. It also marks Prelude’s entry into the 4th largest market for in vitro fertilization (IVF) procedures and will lead to strategic synergies between AFC’s proprietary frozen donor egg bank and Prelude’s MyEggBank, which is one of the largest of its kind in the country.


“Partnering with AFC delivers on our strategy to create a strong presence in the country’s largest metropolitan areas. It also enhances our efforts to unite the country’s top fertility experts and centers boasting the best outcomes, as well as best practices that expand our ability to help patients,” said Prelude Fertility Chief Executive Officer Susan Hertzberg. “As one of the largest fertility clinics in the Midwest, AFC brings nationally-recognized excellence and industry leading success rates to the Prelude Network. They will also help us grow our resources offered to partner clinics through MyEggBank.”


AFC operates three centers, with its headquarters in Gurnee, IL and satellite locations in Chicago and Crystal Lake. It is one of the nation’s leading infertility practices, providing advanced fertility, IVF, and egg donation services to the Chicago market for over 20 years. AFC’s IVF and egg donation success rates are consistently among the highest in the country and exceed national averages. In 2015, according to the Society for Assisted Reproductive Technology (SART), AFC achieved the following live birth rates based on preliminary primary outcome per egg retrieval cycle using a patient’s own eggs: <35 years of age = 57.9%, 35-37 years of age = 57.3% and 38-40 years of age = 36.4%. The 2015 national averages were: <35 years of age = 40.9%, 35-37 years of age = 30.9% and 38-40 years of age = 20.1%.  Additionally, per 2015 SART data, AFC achieved a live birth rate of 83.1% per cycle for women using fresh donor eggs compared to the national average of 50.4%.


Collins Ward, Partner at Lee Equity said, “The partnership with Dr. Sherbahn, Dr. Catenacci and Dr. Jones, along with the outstanding team at Advanced Fertility Center of Chicago further extends and enhances Prelude’s mission for clinic excellence. AFC will offer individuals and families the benefit of Prelude’s national network of premier physicians, medicine and egg freezing capabilities in an accessible and affordable way.”


AFC was established in 1997 by Dr. Richard Sherbahn, an accomplished reproductive endocrinologist and researcher who serves as the center’s program and laboratory director. The center currently maintains a staff of 33 full-time employees at AFC’s three locations, led by Sherbahn and fellow reproductive endocrinologists and infertility specialists Dr. Michelle Catenacci and Dr. Gary Jones.


“Since we founded Advanced Fertility Center, our goal has been to pair clinical excellence with expanding patient reach,” said AFC Founder, Dr. Richard Sherbahn. “For us, it’s about delivering on our promise to help make patients’ childbearing dreams a reality. Joining the Prelude Network is going to significantly expand that potential and impact in ways that weren’t previously seen to be possible.”
