Doctor: Prof. M.D. Hakan Seyisoğlu Hospital: Acibadem Bakirkoy Hospital

After 12 years of unexplained secondary infertility and three heartbreaking miscarriages, my journey felt hopeless until I met Dr. Hakan Seyisoğlu. What sets him apart isn't just his surgical skill—though his laparoscopic myomectomy was flawless—but how he treated our case like a complex puzzle. He spent 45 minutes with us before any procedures, mapping my entire gynecological history on his tablet, connecting dots previous doctors missed. He discovered a subtle uterine septum and mild adenomyosis that others overlooked. His approach was multidisciplinary; he coordinated with a reproductive immunologist in Germany via teleconference during my planning. Now 24 weeks pregnant with our miracle baby, I credit his detective-like thoroughness and refusal to settle for easy answers. At Acibadem Bakirkoy, his team remembered my name every visit, and he gave me his personal WhatsApp for after-hours concerns—a level of care I've never experienced.

Doctor: Prof. M.D. Hakan Seyisoğlu Hospital: Acibadem Bakirkoy Hospital

As a 68-year-old widow, discussing vaginal prolapse felt humiliating, but Dr. Seyisoğlu transformed the experience. He didn't just see a medical case; he saw my dignity. During examination, he kept me covered with warm blankets and explained each step in gentle Turkish, though I'm fluent in English. His solution was unconventional: instead of immediate surgery, he designed a 3-month pelvic floor rehabilitation program using biofeedback devices at the hospital's physiotherapy unit. When we proceeded with minimally invasive sacrocolpopexy, he used a novel mesh alternative from biocompatible material he'd researched himself. Post-surgery, he visited me twice daily, once bringing a diagram showing exactly how he'd anchored everything. Six months later, I'm gardening again without discomfort. His respect for elderly patients as whole people, not just bodies needing repair, restored my confidence in medicine.

Doctor: Prof. M.D. Hakan Seyisoğlu Hospital: Acibadem Bakirkoy Hospital

Our 14-year-old daughter developed sudden severe pelvic pain during a family vacation in Istanbul. As foreigners in emergency at Acibadem Bakirkoy, we were terrified. Dr. Seyisoğlu was called in at 11 PM and immediately recognized it wasn't appendicitis but a complex ovarian torsion. He spoke directly to our daughter in calm, simple English, showing her ultrasound images to explain the 'twisted ovary' like a tangled garden hose. What amazed us was his consent process: he used 3D-printed models to show both conservative detorsion and possible oophorectomy scenarios, involving our daughter in the decision. During surgery, he preserved her ovary against odds, and post-op, he created a 'pain map' coloring sheet for her to track recovery. He followed up for months via secure portal, even consulting with her pediatrician back home. For a teen facing her first major health crisis, he made her feel empowered, not scared.

Doctor: Prof. M.D. Hakan Seyisoğlu Hospital: Acibadem Bakirkoy Hospital

My routine checkup turned surreal when Dr. Seyisoğlu, during a standard transvaginal ultrasound, noticed microscopic vascular patterns suggesting early endometrial pathology—nothing visible to the untrained eye. He called it 'reading the uterine weather map.' Rather than alarm me, he framed it as preventive detective work. Over three weeks, he performed an office hysteroscopy with such minimal discomfort I barely felt it, using a new narrow-caliber scope I'd never seen. His biopsy revealed complex hyperplasia with atypia, but his approach was revolutionary: instead of immediate hysterectomy, he prescribed a targeted hormonal IUD combined with metformin for insulin sensitization, monitoring with monthly 3D ultrasounds. He explained this as 'giving the uterus a chance to heal itself.' Eight months later, repeat biopsy shows complete reversal. He turned what could have been a traumatic cancer journey into a masterclass in organ-preserving precision medicine.
