Sperm retrieval is only possible if at least some sperm production is present. Some images are of models, not actual patients. Usually enough sperm can be obtained to freeze for multiple cycles of IVF. Options then include using a sperm donor and intrauterine insemination IUI or IVF, or having pre-implantation genetic diagnosis PGD performed on the embryos to select ones that carry the normal gene. Acquired ductal obstructions account for most of the cases of obstructive azoospermia and can sometimes successfully be treated by microsurgery. If the problem that underlies poor sperm production is physical rather than genetic, or if a couple wants to have children after the male partner has had a vasectomy that cannot be reversed, surgical sperm retrieval can go ahead.
