The cause of obstruction can be a former sterilization, an infection of the epididymis or congenital absence of vas deferens. When the testicles make no sperm cells at all, of course TESE or MESA is not possible. If sperm cells are obtained, an ICSI procedure (Intra Cytoplasmatic Sperm Injection) will follow.
