lack of live spermatozoa in the semen; see also aspermatogenesis.

a·zo·o·sper·mi·a

azoospermia

/azoo·sper·mia/ (a-zo″o-sper´me-ah) lack of live spermatozoa in the semen; classified as obstructive or nonobstructive depending on whether cause is blockage of the tubules or ducts.

azoospermia

[āzō′əspur′mē·ə]
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.

azoospermia

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

a·zo·o·sper·mi·a

(ā'zō-ō-spĕr'mē-ă)
Absence of living sperms in the semen; failure of spermatogenesis.
[G. a- priv. + zōon, animal, + sperma, seed]

azoospermia

Absence of spermatozoa from the seminal fluid, a cause of male sterility. Sperms may still be being produced in the testes.

azoospermia

absence of spermatozoa in the semen, or failure of formation of spermatozoa.
