About
The Center for Reproductive Endocrinology (CRE) is an independent fertility practice in North Dallas. It was formerly the Dallas office of the Sher Institutes for Reproductive Medicine (SIRM-Dallas) and now operates under the CRE name. Reproductive endocrinologists Dr. Walid Saleh and Dr. Stephen Collins see patients there.
The practice is at 7777 Forest Lane, Suite C-638, near Medical City Dallas. Its accredited facility of about 8,000 square feet includes a clinic-owned embryology lab on site, supervised by an HCLD-certified laboratory director. Because the lab and clinic share one location, patients do not have to go to an outside laboratory. CRE serves patients from Dallas-Fort Worth as well as Oklahoma and Louisiana.
Services include fertility testing and rapid fertility screening, IUI, IVF, genetic testing of embryos, donor egg IVF, and cycles with gestational carriers. CRE also offers family-building care for LGBT couples, elective egg freezing, fertility preservation for patients facing medical treatment, gender selection, and nitrous oxide sedation for gynecologic procedures. Staff can also help patients with financing and insurance questions.

Success rates depend heavily on which patients a clinic accepts, so these numbers should not be used to rank clinics against one another. Cells CDC suppressed for small sample sizes (1-4 cycles) are shown as a dash.
