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.
