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.

The use of testicular spermatozoa for ICSI has, since its introduction in 1992, been very successful in enabling men with azoospermia to achieve genetic fatherhood.10 The first successful pregnancy was achieved after testicular sperm extraction (TESE) from patients suffering from obstructive azoospermia.11 The same year, a pregnancy was reported after a simplified fine needle aspiration technique, called testicular sperm aspiration (TESA).12 In cases of non-obstructive azoospermia (NOA) the outcome is more unpredictable and the sperm recovery rate lower than in obstructive cases.13,14
