Study of AZF Microdeletions in Men with Non-obstructive Azoospermia or Severe Oligospermia with Normal Karyotype Short Title: AZF and Infertility [PDF]

Armaghane Danesh Bimonthly Journal
Background & aim: Microdeletions of the long arm of the Y chromosome cause approximately 6-8% of cases Non-obstructive azoospermia and a smaller percentage of severe oligospermia cases.

Cryopreservation of testicular and epididymal sperm: techniques and clinical outcomes of assisted conception

Clinics, 2013
The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of

Laboratory processing and intracytoplasmic sperm injection using epididymal and testicular spermatozoa: what can be done to improve outcomes?

Clinics, 2013
There are two main reasons why sperm may be absent from semen. Obstructive azoospermia is the result of a blockage in the male reproductive tract; in this case, sperm are produced in the testicle but are trapped in the epididymis.

A comprehensive review of genetics and genetic testing in azoospermia

Clinics, 2013
Azoospermia due to obstructive and non-obstructive mechanisms is a common manifestation of male infertility accounting for 10-15% of such cases. Known genetic factors are responsible for approximately 1/3 of cases of azoospermia. Nonetheless, at least 40%

Testicular macrophages in patients with non-obstructive azoospermia

, 2003
Within the testicular interstitial compartment there is a number of immunocompetent cells like macrophages, neutrophil leukocytes, monocytes, eosinophils and lymphocytes (1, 2). Among them, macrophage population is the largest one and is supposed to influence the function of the neighbouring Leydig cells and the production of testosterone (1, 3).
