Preparing for your appointment

If you notice symptoms of Klinefelter syndrome in yourself or your son, talk to your health care professional. You may be referred to a specialist for testing and diagnosis.

Here's some information to help you get ready for your appointment. If possible, bring a family member or friend with you. A trusted companion can help you remember information and provide emotional support.

What you can do

Before the appointment, make a list of:

  • Signs or symptoms that concern you
  • Medications, including over-the-counter medications, vitamins, herbs or other supplements, and the doses
  • Ages when you or your son reached certain puberty milestones, such as the development of pubic and armpit hair, growth of the penis, and increased testicle size
  • Questions to ask the doctor to make the most of your appointment

Questions to ask might include:

  • Do the symptoms indicate Klinefelter syndrome?
  • What tests are needed to confirm the diagnosis?
  • What are other possible causes for the symptoms?
  • Is a specialist needed?
  • What treatments are necessary?
  • What are the side effects and expected results of treatment?
  • What kind of special therapies do you recommend?
  • What kind of support is available?
  • How can I learn more about this disorder?

Don't hesitate to ask other questions during the appointment.

What to expect from your doctor

Your doctor may ask questions such as:

  • When did you first notice that something may be wrong?
  • What signs and symptoms have you noticed?
  • When did you (or your child) meet growth and developmental milestones?
  • Do you have problems with fertility?
  • Have you had any previous tests or treatments?
