See urologist: You need to have a fertility evaluation by a urologist. This typically includes semen analysis (usually 2 samples) and blood tests for testosterone, lh, fsh, prolactin. With this information, your urologist will be able to make a diagnosis and hopefully offer treatment.

Hormone Blues: If you are hypo gonadal then hormone replacement can help you to produce sperm. I assume you have had treatment since you imply failed attempts. Having sperm is not the same as having functional sperm. You may have poor quality sperm that cannot fertilize an egg. Ivf with icsi (sperm injection into the egg) is very effective if hormone therapy alone is not. See specialist for details.
