Etymology: Gk, a, zoon, not animal, sperma seed
lack of spermatozoa in the semen. It may be caused by testicular dysfunction, cancer chemotherapy, or blockage of the tubules of the epididymis, or it may be induced by vasectomy. Infertility, but not impotence, is associated with azoospermia. Compare oligospermia.

azoospermia

Complete absence of sperm in the semen, with resultant infertility.

Azoospermia
• Pretesticular—due to absence of FSH secondary to hypopituitarism, hyperprolactinemia and FSH suppression by exogenous androgens.
• Testicular—The most common cause, in which the testes are atrophic, typically due to cryptorchidism or Sertoli cell-only syndrome, but also orchiditis, cancer, surgery, trauma or radiation.
• Post-testicular—due to vasectomy, agenesis of vas deferens or ejaculatory dysfunction.
