Dr. Rey is a Spanish obstetrician–gynecologist with a long-standing focus on minimally invasive gynecologic surgery, assisted reproduction, and academic research. She earned her MD (Medicine and Surgery) and completed her residency in Obstetrics and Gynecology at Hospital Universitario Virgen del Rocío (Seville, Spain), receiving an Excellent evaluation each year and the Best Resident Award in 2004. This distinction enabled an external rotation with Professor Magrina at the Mayo Clinic (Arizona, USA), an experience that consolidated her commitment to minimally invasive surgery.

During medical school, she was awarded a scholarship by the University of Seville to join a research project in the Department of Physiology, collaborated on forensic medicine initiatives, and completed a one-month clinical internship at the Civil Hospital of Guadalajara (Mexico), where she developed a strong interest in gynecology.

Following her U.S. training, Dr. Rey pioneered laparoscopic surgery at the hospital where she trained and earned a PhD from the University of Seville. Her doctoral thesis, Repercussions of Hysterectomy on Quality of Life, Urinary and Sexual Function, was awarded Summa Cum Laude and received the Best Doctoral Thesis Award from the Seville Medical Association.

In 2006, she founded a specialized clinic in Seville dedicated to assisted reproduction and minimally invasive gynecologic surgery, which has since received multiple national awards for excellence. In 2015, she developed a radiofrequency approach for uterine fibroids (the VREY method), initially driven by the clinical need to improve pregnancy outcomes in women with fibroids. The technique has been adopted internationally, supported by training programs hosted at her clinic and publications in high-impact peer-reviewed journals, including reports of pregnancies achieved after treatment.

She currently combines her clinical work and the leadership of her Seville-based clinic with teaching in the MD program at Loyola University Andalusia.
