Varicocele repair and Zero sperm

Selene

Hi, my husband was diagnosed with azoospermia 4 years ago. He had genetic testing and everything normal. The only thing that came back not normal was his testosterone levels and he had Varicocele vein. He went into surgery on April 19, we should be retesting this month to see if the surgery was a success. Has anyone Husband had a Varicocele repair surgery and it be successful?
