Mr Hussain Alnajjar's patient interactions are professional, reassuring, and clear. He provides thorough explanations for diagnoses and various procedures, including treatments for Peyronie's disease, varicocele, and urological cancers, with many patients reporting successful outcomes.

His expertise covers a broad range of general urology and andrology issues, including circumcision.
Mr Hussain Alnajjar is simply a top class urological/andrological consultant and a phenomenal human to boot. He knows the disciplines inside out, is methodical, kind, very skilled and surrounded by the best team. If you have a urological or androlological issue he is the consultant to go and see. I was incredibly lucky to come across him.
I had micro-TESE surgery with Mr Alnajjar and the entire experience was exceptional. He successfully retrieved sperm for us, which has now given us the chance to move forward with IVF next year. What stood out most was how personal and reassuring his approach was. We had met him a few times before the procedure and he always made both me and my wife feel calm, confident, and fully informed. The follow-up care has been outstanding — nothing felt rushed, and every question was answered clearly. His PA and the communication throughout have also been first-class. A genuinely brilliant surgeon and a top professional. Highly recommended.
I cannot thank Mr Alnajjar enough. Having suffered with erectile disfunction and my relationship with my partner becoming strained, my partner found Mr Alnajjar. After three consultations over a period of 7 months, my relationship with my partner has been reignited. Everything is now working. At 66 I'm a very happy man.
Excellent and professional care
I had a inflatable penile prosthesis and I am extremely satisfied with the outcome. It has given me my life back. Mr Alnajjar is an excellent surgeon and human being. From the first consultation he demonstrated deep medical knowledge and precision and empathy. I want to express my deepest appreciation and gratitude to Mr Alnajjar for the exceptional care and surgical expertise. The surgery itself was carried out flawlessly and the result has by far exceeded my expectations both functionally and in terms of restoring my confidence and quality of life.
Very knowledgeable and professional. Recommended surgery and undertook within a month.
I recently had a consultation and procedure with Mr. Hussain Alnajjar, Consultant Urological Surgeon and Andrologist, and I couldn't be more pleased with the care I received. Mr. Alnajjar was thorough, reassuring, and highly professional throughout the entire process. He explained everything clearly, made me feel at ease, and the procedure went smoothly with excellent results. I highly recommend him for anyone seeking expert urological care.
Mr Alnajjar was the most welcoming, sympathetic, warm and helpful consultant I could wish for. His manner and general bonhomie put me at ease and I found his advice clear and understandable. I felt like he was on my side! I would recommend Hussain to anyone as a kind, knowledgeable and gentle doctor.
Excellent colleague to work with. Very experienced and knowledgable Andrologist who takes care of his patients.
