Does anyone know much about klinefelter syndrome (XXY chromosome)?

I just got diagnosed with klinefelter syndrome, my doctor told me my testicles are tiny and don't produce sperm or much testosterone. Therefore im completely infertile. Im on a waiting list to see a specialist about getting on testosterone replacement therapy. Has anyone else been on TRT and can share with me their experiences.
