    I believe in providing my patients the type of care that I would want provided for myself or my family. I believe in quality of life being most important in managing my patients’ problems.I believe in giving my patients time to tell their story, and value and appreciate their time, waiting to see me. I want to give my patients all the information they need to make a truly informed decision in their treatment. My role is to navigate them through all the complexity of medical decision making, not to tell them what to do. I try to talk to them as a friend or neighbor, and avoid a lot of medical jargon.If I can fix their problem with a surgical approach, then I will do so with greatest care to detail, to maximize the success and minimize the likelihood of harm. I always remember the Hippocratic Oath, of “do no harm” to my patients.After doing this for over 30 years, I truly believe, that building a relationship with my patients, so that they build trust in me as a person and as a doctor, so that they are more likely to follow my advice and recommendations, is the way to practice good medicine.I was born to two parents who were both doctors. So I have been around medicine all my life. Ever since I can remember, that’s all I wanted to do. What drew me to a career in medicine, especially surgery, was the immense satisfaction that I felt when I was able to make a difference in someone’s life. Everyday I get this feeling when I am taking care of someone, either in the office or in surgery. This has kept me going for over 30 years, and has made it easier to bear the burden and fatigue on some days when it seems overwhelming. If I had to do it all over again, I certainly wouldn’t change my career choice.Special Clinical Interests: I am currently focusing on minimally invasive procedures to treat enlarged prostates. I also focus on urinary incontinence in men and women, as well as sexual dysfunction in men.

His top areas of expertise are Urinary Tract Infection in Children, Urinary Tract Infection (UTI), Neurogenic Bladder, Ureteroscopy, and Reconstructive Urology Surgery.

    What is the definition of Leydig Cell Testicular Tumor?

    A Leydig cell tumor is a tumor of the testicle. It develops from Leydig cells. These are the cells in the testicles that release the male hormone, testosterone.

    When should I see a Leydig Cell Testicular Tumor doctor in California, US?

    There are various reasons why you may want to see a specialist, such as: 

    • Your primary care provider recommends it. 
    • Your condition requires expert knowledge and specialized care. 
    • Your symptoms persist or worsen despite treatment. 
    • You need specialized testing or procedures. 
    • You want a second opinion.  

    What should I consider when choosing a Leydig Cell Testicular Tumor doctor in California, US?

    It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

    How does MediFind rank Leydig Cell Testicular Tumor doctors in California, US?

    MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

    What types of insurance are accepted by Leydig Cell Testicular Tumor doctors in California, US?

    Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

    How can I book an appointment online with a Leydig Cell Testicular Tumor doctor in California, US?

    MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Leydig Cell Testicular Tumor doctor search results page. 

    Why is it important to get a second opinion from a different Leydig Cell Testicular Tumor doctor?

    Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

    How can I prepare for my appointment with a Leydig Cell Testicular Tumor doctor in California, US?

    Prepare for your appointment by gathering the following items: 

    • Copies of medical records (dating back at least one year) 
    • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
    • Family history of disease 
    • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
    • Allergies to medications, food, latex, insects, etc.  
    • List of questions and concerns 
    • Your insurance card 

    You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

    What questions should I ask my Leydig Cell Testicular Tumor doctor?

    Here are some sample questions: 

    • Can you explain in simple terms what this condition is and how it’s treated? 
    • What symptoms or side effects should I watch for? 
    • What tests will be involved, and when can I expect results? 
    • Are there other specialists I need to see? 
    • What’s the best way to reach you if I have follow-up questions? 

    How can I learn about the latest clinical trials and research advances my Leydig Cell Testicular Tumor doctor may know about?

    MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

    MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

    Can I filter my search to show male or female Leydig Cell Testicular Tumor doctors in California, US?

    Look for the filter feature on the left side of the Leydig Cell Testicular Tumor doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

    Can I filter my search to find a Leydig Cell Testicular Tumor doctor that offers video calls?

    Look for the filter feature on the left-side of the Leydig Cell Testicular Tumor doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
