Esteban O. Brown

About

Dr. Esteban O. Brown is an obstetrician-gynecologist associated with the Reproductive Institute of South Texas, which does business as The Valley's Fertility Center, in McAllen, Texas. Since August 2025 the practice has stated that he no longer offers infertility consultations or treatment. He continues to provide supporting services on the orders of a referring physician, including cycle monitoring for clomiphene, letrozole and natural cycles, baseline and midcycle ultrasounds, hormone testing, intrauterine and donor insemination, and surrogacy monitoring, while the clinic also offers semen analysis. Consultations and IVF care for the practice's patients are now handled by a separate reproductive endocrinologist through telemedicine and a San Antonio laboratory.
