###Human: I am a male suffering from infertility. Please advise. ###Assistant: Hi. You are suffering from azoospermia. Pre and post-testicular azoospermia are frequently correctible, while testicular azoospermia is usually permanent. Go for serum prolactin level, a testicular biopsy may be required to find out the exact cause so I would advise you to consult local urosurgeon as physical examination is also required.
